Metric Measures Mat

(0)
Students use this one page mat as an aid when making metric conversions. You can laminate several copies and make them available for student use. Or, do as I do, purchase heavy weight sheet protector sleeves ($20 for 100)and have students slip various papers inside. Using a erasable marker they can write information of the protector, erase, and reuse an unlimited number of times. Saves laminating and paper cost.
Finding the Least Common Multiple (LCM) Pack

Finding the Least Common Multiple (LCM) Pack

(0)
Students use the "M" method when finding the LCM! Each year my 5th grade students always confused Least Common Multiple and Greatest Common Factor. In an effort to help them keep the two straight, I try to make the way I present one very different from the way I present the other. For LCM, I use what I call 'The M Method'. Using a large M as a visual greatly helps my students distinguish between LCM and GCF. I created this pack to introduce the method to my students. The pack includes a LCM matchbook fold-up. A poster, a half sheet copy of the poster for a student resource and a two page worksheet. This pack INCLUDES the Least Common Multiple Poster, which is listed separately in my shop. If you buy this, there is no need to purchase the visual. To learn how to print a poster visit my Making Posters blog post. When assembling the matchbook fold-up, run a two-sided copy--the front cover (upside down intentionally for easier copying) and the inside. With the inside facing you, bring the top of the paper down to the bottom horizontal line and fold. Then bring the bottom of the paper up and fold on the bottom horizontal line. The result will look like a giant matchbook.
Canceling to Multiply Fractions - "Cross-Eyed Method" Fold-Up and Practice Pages

Canceling to Multiply Fractions - "Cross-Eyed Method" Fold-Up and Practice Pages

(0)
Students love the silly name! After teaching my students how to multiply and divide fractions, I have students practice both skills until they have them mastered. Over the course of this process, students experience how unappealing multiplying larger numerators and denominators can be...not to mention how tedious reducing ‘large’ fractions to lowest terms can be. This product also contains a 2-sided practice page as well as answer keys. Once the above has been accomplished, I share what I like to call “The Cross-Eyed Method”. Most textbooks call this "Canceling before Multiplying Fractions". Essentially this method reduces the fractions before multiplying. Therefore, not only are the numbers you multiply smaller, but if done completely your final answer will be in lowest terms! This packet contains the materials needed to introduce the “Cross-Eyed Method” as well as practice the method. • The first product is a matchbook fold-up. This fold-up explains how the method works and gives several examples. This would be a great resource for a math journal. Pictures of assembled fold-up is included. • The second product in this packet is a ‘quirky’ fold-up that allows the students to practice the ‘cross-eyed’ method. This fold-up includes a front, inside and practice problems cards. I have included several pictures, as well directions, on assembly and use of the this product.

Multiplication Strategies - Lattice Method

(0)
Students have fun multiplying with this method! I am always looking for a variety of different strategies my students can use to solve a multiplication problem. One of those ways is the Lattice Method (aka: Gelosia Method). I am currently teaching this method to my students and they LOVE it! I created this 5 page packet to use with my students. The packet includes a 1 page handout that lists the steps, a 2 page fold-up that can be inserted in a math journal, and a two page worksheet. The single page handout works great as a stand alone resource or could easily be made into a poster. For directions on how to make a poster visit my blog post on making posters.
Identifying Composite and Prime Numbers

Identifying Composite and Prime Numbers

(0)
Students learn about composite and prime numbers! This fold-up gives the definitions for both Composite and Prime Numbers. It also includes an example of each. The fold-up is a half sheet two-flap resource that would fit well in a math journal or stand alone. A second inside page option is also included. This inside has a definition for both prime and composite numbers that does not use the word divide but factor instead. I have chosen to include this second option, not because the first set of definitions was incorrect, but because some teachers may prefer using the word 'factor' instead of divide. Also, included is a double-sided worksheet that requires students to list factors for a given number and then check if the number is composite or prime. An answer key is also included.

Fraction Attraction Pack: Three Strategies to Compare and Order Fractions

(0)
Students tackle fractions with confidence while using Fraction Attraction resources! This packet contains: • A Fold-up which would fit well in a math journal or as a stand alone resource. The fold-up explains and gives an example of three different strategies that can be used to examine fractions. Once one of these strategies is used, fractions can be compared or ordered. • A full-sheet handout. This handout contains the same information as the fold-up, just in a full-sheet format. I find this format works well as a quick reference sheet. In addition, many students like to take it home and share with their parents. This page could also be made into a poster. • A two page worksheet. The worksheet focuses on comparing two fractions. Students are provided a workspace for each problem. Students are also asked to indicate which strategy they chose to use to solve the problem. • A one-sided cut and paste worksheet is also included. The cut and paste sheet focuses on ordering three fractions from least to greatest. • Answer keys for all worksheets are also included.

Making the Distributive Property Work for You

(0)
Help students and parents understand the distributive property! The new Common Core Standards promote teaching students a variety of ways to solve a problem. Using the various properties of math are utilized a great deal. Most of my students catch on to the Communative, Associative, etc. But the Distributive really causes a great deal of frustration. I created this tri-fold handout for my students to use as a resource they can refer to when asked to use the Distributive Property. The original handout has two different type of problems: Example One and Example Two. I have taught my 5th graders both. It, however, dawned on me that not all teachers may want to delve into Example Two since it is a bit more in depth. So, I created two covers for this handout: One which includes both examples and a second that separates the two examples. This allows the teacher to only teach one or the other or perhaps teach them at different times. The covers are upside-down for easier front and back copying for the tri-fold finished product. Please visit my blog post for additional pictures of this handout and instructions on how to use the fold-up.

Flip for Math: Adding and Subtracting Fractions with Unlike Denominators

(0)
Help your students understand how to add and subtract fractions! The purpose of a ‘We Flip for Math’ Flip Book, is to provide a struggling student witha step-by-step guide to take them through the process they are struggling with. I have various flip books available in my classroom, but only after I’ve taught the concept and we have practiced it a number of times. The complexity of some skills can be quite challenging for some students. Being able to remember all the steps can become overwhelming for some. A flip-book can help walk these children through the process. In addition, I have found flip-books can be helpful when sending home homework. Including a flip book can make for very happy parents! This packet contains two flip-books. • Adding fractions with with unlike denominators. • Subtracting fractions with unlike denominators. To assemble simply run single-sided copies of both pages. Laminate for durabillity. Cut on the dotted line. Put the pages in sequential order--cover should be on top. Bind or staple (binding works best) across the top!

Mean, Median, Mode & Range Fold-Up Resource

(0)
Hands-on resource they will use time and time again! This fold-up includes definitions and examples of minimum and maximum value, mean, mode, median and range. It will fit perfectly in a math journal or as a stand alone resource. When I create a new fold-up, I try to imagine all the possible ways a classroom teacher may want to use it. This fold-up has a number of possibilities. 1) You can choose to run a complete fold-up. The fold-up will have words on the outside and definitions and an example inside. 2) A complete fold-up, but you could choose to only have definitions on the inside (perhaps both definitions and example is too 'busy' for you students). 3) You can have the students assemble either of the two fold-up types mentioned above--just run the appropriate template for them to glue the parts on. 4) Run the cover only and have the students glue the inside in appropriately...or vice-vers-a. I also included two 'squares' of information on how to find the median when you have two middle numbers and what to do when you figure that median and have remainder 1. If you do run a complete fold-up, be sure to do a trial print to make sure the front and inside fold up correctly.

Perfect for a math journal! This Numerical Expressions Tri-Fold Up will fit nicely in a math journal or as a stand alone resource. The cover of the tri-fold is intentionally upside down for easier assembly. I would recommend running just one copy to make sure it folds up properly, before running multiple copies. Included with this product: • A definition of what a numerical expression is as well as what it means to evaluate a numerical expression. • Examples accompanied by a 'think aloud' script to demonstrate how to write a numerical expression from a given 'story'. • 2-sided practice page, as well as answer key.

A flip-book can help walk these children through the process. In addition, I have found flip-books can be helpful when sending homework home . Including a flip book can make for very happy parents! This packet contains a ‘four-in-one’ flip-book. • Section 1 provides a step-by-step guide for dividing a fraction by a whole number. • Section 2 covers how to divide a whole number by a fraction. • Section 3 demonstrates how to divide two fractions. • Section 4 focuses on how to divide mixed numbers. • Ready-made index tabs for marking each of the four sections. I intentionally chose to combine all four types of problems into one flip book, as I feel it is important that students be able to identify which type of problem they are trying to solve and then turn to that desired section.

Converting Customary Measures Fold-Up & More

(0)
Students master customary measurements! Converting Customary Measures can be challenging for many students. I created this packet with those students in mind. Included in this packet are two fold-ups. The first fold-up is a tri-fold fold-up which when assembled lists the basic conversions for customary length, capacity and weight. The second fold-out is a matchbook fold-up. This fold-up explains how to make conversions between two measurements. Two examples are also give. A 2-sided practice page is also included. The questions on the practice page are written is such a way that requires the students to show their thinking while solving the problem. An answer key is provided. I also included two pages of pictures and instructions on how to assemble the fold-outs. These materials are aligned to Common Core Standards required for 5th grade.

Two Methods to Teach Prime Factorization - Foldables and More

(0)
Two different visuals...you choose! This packet explains two methods for prime factorization--The ‘tree method’ works from the top down and focuses on factors. The ‘birthday cake method’ works from the bottom up and focuses on division. The tree method is most widely taught and used. It is the way you and your parents will be most familiar with. I have found, however, that the ‘birthday cake method’, while not as widely used, seems to be the method my students prefer and have the most success with. I have created a packet that will provide you with the necessary resources, regardless of which method you decide to use with your students, Included in this packet are two matchbook fold-ups--one for each method, a mini-book for each method and a two-sided practice page for each method. Detailed answer keys for practice pages and both mini-books are included as well.

Working with Decimals - Fold-Ups Galore

(1)
FOUR fold-ups for one GREAT price! This packet contains four different decimal fold-ups. Each fold-up is designed to fit perfectly in a math journal or be used as a stand alone resource. • The first fold-up divides adding and subtracting decimals into an easy to follow three step process. Run front cover on one side of paper and inside steps on other side. Trim on grey line for a nice fit in any math journal. • Fold-up number two is a half sheet, two-flap fold-up that shows multiplying decimals in two easy steps. Two fold-ups per sheet. Again, run cover on one side of paper and inside on the other side. Note that the cover is upside down for easier assembly. • Fold-up number three shows three types of division with decimals: Dividing a decimal by a whole number, dividing a decimal number by a decimal number and finally, dividing a whole number by a decimal. Don't teach all three? Just cut away the type you don't want. Think all three in one fold-up is too much for your students? Cut all three apart and present one at a time. Run cover and inside as described above. Trim on grey line for a nicer fit in a math journal. • The fourth (and final) decimal 3 flap fold-up, explains rounding decimals, comparing decimals and converting a decimal to a percent. Run copies as stated above. Trim on grey line for a nicer fit in a math journal. As always, I recommend you run a test copy just to make sure you have the front and back on right and the fold-up folds up correctly.

Knowing how to use Compatible Numbers is very helpful when tackling a long division problem! The purpose of a ‘We Flip for Math’ Flip Book, is to provide a struggling student with a step-by-step guide to take them through the process they are struggling with. I have various flip books available in my classroom, but only after I’ve taught the concept and we have practiced it a number of times. The complexity of some skills can be quite challenging for many students. Being able to remember all the steps can become overwhelming for some. A flip-book can help walk these children through the process. In addition, I have found flip-books can be helpful when sending homework home . Including a flip book can make for very happy parents! This packet contains a 3-part flip-book that focuses on using compatible numbers to estimate division . • In the first section, the definition and examples of compatible numbers are given. Also, in the first section is a step-by-step guide for using compatible numbers to estimate division problems with a single-digit divisor. • The second section, shows how to use compatible numbers to estimate division problems with a double-digit divisor. • The third section, demonstrates how compatible numbers can be used to ‘jump-start’ the solving of a double-digit division problem. • Also included is a 2-sided practice page. Answer key is also provided.

Division Strategies: Decomposing the Dividend Strategy Foldable & Practice

(0)
Give your students the tools they need for tackling long division The new Common Core Standards for Math prompted me to create this Decomposing the Dividend Strategy pack for use with students and with parents. The Decomposing the Dividend Strategy encourages students to break the dividend into parts that can be divided easily. The long-term goal of this method is for students to solve the division problem mentally. In my experience, it will take a great deal of practice before students will master the ability to solve the problem mentally using this method. I have found that many higher achieving math students will pick up on the strategy and choose to use it. This packet contains: • A tri-fold fold-up (front and back) that shows how the strategy works. It would make a wonderful resource for both students and parents. • A 2-sided practice page as well as a detailed answer key.

Knowing Divisibility Rules gives students an advantage! This pack includes Individual Divisibility Rules Fold-Ups (2 per sheet--just cut apart on grey line and present one at a time). Once printed and assembled you will have 10 individual divisibility rule fold-up for 2, 3, 4, 5, 6, 7, 9, 10, 11, and 12. The inside of all of these fold-up could be enlarged and used as a poster for your classroom. To learn how to make a poster be sure to visit Mrs. B's Best Blog Also included are two fold-ups that summarize five divisibility rules each. These fold-ups would work if rules have already been taught and the student just needs a resource to refer to. I have also included ten 18 question worksheets to accompany each divisibility rule. An answer key is also provided. As always, when printing be sure to run a test copy to make sure the fold-ups fold up properly. Want to see pictures of the product? Stop by Mrs. B's Best Blog.
Fractions - R.E.D. (Review Every Day)

Fractions - R.E.D. (Review Every Day)

(0)
Give students the review they need to master the skill! If there is one thing I have learned since I began teaching math to 5th graders 10 years ago, it is that students must practice a skill repeatedly. Just because a student is able to change an improper fraction to a mixed number for the chapter test, does not mean they will remember the skill a month later. With this in mind, each day I set aside a portion of time to practice previously taught skills. From this practice, RED, Review Every Day, was born. This packet contains 28 quick half-sheet reviews focused on fractions. This Review Every Day includes the following fraction skills: Reducing fractions to lowest terms, comparing fractions, ordering fractions, writing equivalent fractions, finding the least common denominator, adding & subtracting fractions with alike and unlike denominators, multiplying and dividing fractions with a whole number, multiplying and dividing two fractions, multiplying and dividing mixed numbers, changing improper fractions to mixed numbers and changing mixed numbers to improper fractions. Please note that this packet does NOT teach the skill, but only serves to review the skill after you have taught it to the students. Each review has anywhere from 8 to 12 questions. In my classroom I spread the 28 lessons out and usually do not use them one day after another. I have other RED lessons that I would mix and match. So, for instance, Monday might be Fractions 1 and Tuesday might be Decimals 1. By Friday, I may be ready to use Fractions 2. Each review is a half-sheet. Lesson 1 and Lesson 3 are on page 1. Lesson 2 and Lesson 4 are on page 2. I do this intentionally. If you run page 1 on the front and page 2 on the back and then cut the sheet in half, you will have Fractions 1 on the front and Fractions 2 on the back. The entire document is set up this way. This saves paper, and allows the teacher to teach the lessons in order and in a more efficient way. At the back of the packet you will find the answer key which provides the answers to all questions.

Change a Mixed Number to an Improper Fraction & Back Again and Practice Pages

(0)
Teach your students fraction basics! This product is a two part fold-up. Part one is "How to Change a Mixed Number to an Improper Fraction". Part two is "How to Change an Improper Fraction to a Mixed Number". Also included with this product is a 2-sided practice page and answer key. Each fold-up defines how to make the conversion and shows an example. As the teacher, you can decide if you want to cut the two apart and present each at different times or leave the two together and present at once. The choice is yours. Either way, the fold-up will fit nicely in a math journal (just trim on the grey line before distributing to students for a better fit) or work as a stand alone resource. The top portion of the fold-up was intentionally left blank and could be used as a place for students to record a few examples of their own. The front cover is intentionally upside down, this makes for easier printing. I would recommend, however, that you run a test copy to make sure everything folds up properly.
