Place value is the corner stone for building numeracy. Having a base ten mat that shows the verbal – both the place value and the name for the manipulative, the numerical, as well as the pictorial helps students build stronger connections and deepen their understanding as they work with place value. This is a mat for units, rods, flats, and cubes. There is a version also for legal paper.

One of the gold standard resources for mathematics is NCTM’s Navigating Through…series. Each grade band series includes books for Navigating through - Algebra, Data Analysis and Probability, Discrete, Geometry, Measurement, Number and Operations, and Problem Solving and Reasoning. For Middle School and High School there is also a Connections book in the series. The investigations in the series provide opportunities for students to reason, conjecture, and communicate about mathematics. Having used the series for years, I saw a need to quickly be able to locate potential lessons and activities. This compilation includes the lesson title and the goals. On a PC use “Ctrl F” and on a Mac use “Command F” to search for lessons and activities by key word.

Do trade books have a place in today’s mathematics classroom? Yes! Incorporating literature into the mathematics classroom at any level can increase student engagement, can make mathematics come alive and give meaning, and can help to differentiate instruction as well as support ELL/ESL students. See several samples of the mathematics that can be experienced by students through well-known pieces of children’s literature. Experience how the way mathematics is presented can make mathematics more accessible and understandable for students at all levels. This resource contains eight suggested activities plus "Domino Math" activity to engage students AS YOU READ, for students to experience BEING A MATHEMATICIAN, and provide students authentic OPPORTUNITIES FOR WRITING. The suggested activities can be adapted for large and small groups, centers, learning stations and for intervention. Domino Addition A MUST HAVE book for all teachers. This resource is good for students with and language-based learning deficiencies. We'd like to hear about your experience with our resources.

The number three is the next number for the 12 Days of Christmas. Students from kindergarten through high school work with the number three in one of the most representative of formats – the triangle. The focus for today is triangular numbers. Triangular numbers are polygonal numbers where the number of vertexes in a figure formed by a certain polygon is three.

Day five has students writing about circles. The “Writing About…” activity has proved very popular in all disciplines as it supports making writing about mathematics accessible to many students who might otherwise be challenged. The facilitation notes are provided below. As an alternate task (or additional) there is a discrepant activity. They then write about the investigation and the outcomes as well as their prediction.

The number five is the next number for the 12 Days of Christmas. Secondary students can choose from a variety of investigations all relating to circles. The most basic task is the classic circle in a square. I have also included a figure with various points still shown that some students may find beneficial as they are working. For an alternate task a circle has been circumscribed as well as inscribed in the square. For an interesting twist, have students study the figure and generate a list of questions that might be of interest based upon the figure. Again a figure with selected points has also been provided. Other tasks can be given to students based upon any of the other figures that have been included as well as researching Descartes' Circle Theorem.

Five golden rings inspire tasks that involve writing about circles to working with circles. There are several options depending upon the needs of your students. • The first task is writing about what makes zero special. Zero is framed in a circle as a visual prompt for students to think about a circle not having any sides. • The second task has students going on a “Circle Hunt”. • The third task has students using circle counters to decorate a Christmas tree (work mat provided) while composing and decomposing numbers. Facilitation notes for the task are provided.

The activities in this 20 page packet on A Study of the Real Number system include two application probes, 2 investigations, 7 tasks to probe students deeper into their study of this topic, and several pre-assessment and writing activities that support the development of the language of mathematics. Student activity and investigation sheets are provided as well as teacher facilitation notes. Many of these activities can be extended into the Complex Number System as well.

Patterns anyone? Mathematics has at its heart patterns. Students must be provided multiple opportunities to discover and find patterns on their own if they are to make meaning and develop understandings. See how various types of patterns can be explored using the TI-15.

One Duck Stuck, by Phyllis Root, is a beloved children’s book. Not only does the story engage children it can also serve as a foundation for many mathematical investigations for primary mathematicians. Using doubles is one of the foundational strategies for primary mathematicians as they are building number sense. Connecting this study to a familiar story makes these activities more engaging for students. Additional literacy connections are suggested for use with introducing the concept of doubles. Questions are provided that can be used during the development of the activity to determine the desired focus of the lesson. It is very important that young mathematicians understand that numbers are quantities represented by numerals, pictures, numerals, etc. Materials are listed for each of the activities. The 12 pages include both black line masters as well as color masters have been provided. Suggestions for preparing the materials have been noted as well to facilitate making classroom sets for long term use.

The number 9 is considered by many to be lucky and to be magical. Students of all ages can enjoy any of the vast selection of activities centered around the number 9 found in the K3 and Intermediate/MS packets. For secondary students I am taking this opportunity to share one of my favorite problems from a famous historical mathematics document: The 9 Chapters on Mathematical Art.

The number 9 is considered by many to be lucky and to be magical. Students of all ages enjoy working with the number 9 and experiencing its magic firsthand. Check out the K3 packet for introductory activities that may be appropriate for some students. For intermediate and middle school mathematician’s, multiplication patterns and division patterns will be extended. We'd like to hear about your experience with our resources.

Today is all about the wonderful number 10! Our number system is base 10. There are activities in the K3 and Intermediate/MS packets that you may find meet the needs of some of your students as well. For secondary students, I had fun scouring my notes and files pulling together a collection of puzzles that involve 10 in some form! You can pick and choose based upon the needs of your students! The fifth puzzle is a classic puzzle via Japan. We'd really like to hear about your experience with our resources. Just give it a star rating then tell us what you think, simple as that!

Today students of all ages will play will working with one of my favorite mathematical topics of all time: Pascal’s Triangle! Intermediate and middle school students, if they are not familiar with the triangle, can investigate the basic structure of the triangle using the 12 Days of Christmas as the backdrop. See the K3 activity for some questions/patterns that are appropriate for introductory work with the triangle. Blank triangles and work mats are also provided in the K3 activity pack. Be sure to have students first investigate the triangle and discover the basic pattern of creating the triangle before they move forward. This activity is also great for students with dyslexia and language-based learning deficiencies. Please leave a review.
