Day 7 provides the opportunity for younger mathematicians to investigate patterns on the calendar. There are a series of tasks that can be posed. The current December 2015 calendar is used but this activity can be easily adapted for any calendar month. There is also a place for the children to create their own riddles that can be saved and used later for centers and learning stations. This activity is also good for students with dyslexia and language-based learning deficiencies. Please review the activity.

Understanding multiple representations are one way that students show evidence of fluency with a topic. See how using multiple representations while investigating place value can help students deepen their understandings of this foundational topic. Several pieces of children’s literature will be shared as well.

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. 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.

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.

Today students of all ages will play will working with one of my favorite mathematical topics of all time: Pascal’s Triangle! Beginning and young mathematicians will be introduced to the triangle. Students can spend a lot of time “tinkering with” the triangle as they discover more and more patterns. The following is an adaptation of one of the chapters in the Primary Activity Packet for Rooster’s Off to See the World, eBook by Tammy L Jones that can be found here on TES USA or TES UK. This activity is great with students with dyslexia and language-based learning deficiencies. Please leave a review.

Eleven is the first “teen” number beginning mathematicians encounter. Eleven is also the first 2-digit prime number. Older mathematicians will study other 2-digit prime numbers using the Sieve of Eratosthenes. 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!

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. For younger mathematicians studying the patterns in the 9s column on a numbers chart can reveal some mysteries of the number 9!

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! A few activities are given for you to choose from to meet the needs of your students. First students can create a Christmas tree using their pattern blocks. There is a triangle template provided for younger mathematicians who would benefit from having a work mat to follow.

Today is all about the wonderful number 10! Our base 10 number system has the number 10 at its heart! Today there are a few activities to choose from to meet the needs of your students. First is a writing prompt that gets students thinking about very large and very small numbers. We'd really 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!

Eleven is the first “teen” number beginning mathematicians encounter. Today’s activity employs children’s literature and manipulatives. If possible, use the children’s book 12 Ways to Get to 11 by Eve Merriam. Have Cuisenaire rods, unifix cubes, or other manipulatives on hand for students as needed. Based upon the individual needs of your children show them the title and allow them to work in pairs to see how many of the 12 ways they can discover to make 11. Alternatively, as you read the story allow the children time to model the various compositions of 11 that are shown in the story. Encourage children to use various representations for their models – drawings, words, equations, sketches of their manipulative models, etc. This activity is good for students with dyslexia and language-based learning deficiencies.

For the last day of the 12 Day of Mathematics, secondary students will look at abundant numbers – since the 12 Days of Christmas implies an abundance of gifts! (See Intermediate/MS activity if more appropriate for your students). We'd really like to hear about your experience with our resources.

For the last day of the 12 Day of Mathematics, secondary students will look the abundance of gifts that were given over the course of the 12 days. They will calculate the total number of gifts given in all! And they will think of questions that might be raised when working on their calculations.

Eleven is the first “teen” number beginning mathematicians encounter as well as the first double digit prime number. The K3 and Intermediate/MS packet have activities associated with those themes if needed to support the needs of your students. Secondary students will be investigating the connection between a previous topic - Pascal’s Triangle – and powers of 11. We'd really like to hear about your experience with our resources.

The number two is the next number for the 12 Days of Christmas. Students from kindergarten through high school work with the number two in various formats. Today younger mathematicians will be investigating doubles, skip counting by 2, and multiplying by 2. Two of Everything by Lily Toy Hong is a great piece of children’s literature to connect to these activities.
