# Prime and Composite Numbers: A Math Sort

### Description

Are you familiar with concept sorts? Many people use "sorts" with their spelling or word work programs, but sorting and categorizing can be extremely effective learning strategies for MANY areas--including prime and composite numbers!

I have found sorts to be particularly effective in my math instruction, and I am excited to begin offering some of these sorts to you! If you are unfamiliar with how sorts are used, I have included a full blog post with photos to help get you started!

**So...what's included in THIS resource?**

- The cards needed to do ONE concept sort on prime and composite numbers. This is a perfect extension lesson or replacement for a more computation based lesson in a textbook! The cards for one sort are included--and the headers to sort them two different ways.

- A blog post with photos that explains EXACTLY how I completed a different sort with my own students. Feel free to get creative and try different approaches—but I have given one highly effective and efficient way to do this.

- A “Show What You Know” sheet that follows the rule of the sort. Use as independent practice or as an assessment after you have done a sort to see what the students know and what they still need to learn. Many of these also ask students to explain their thinking—a key part of the CCSS!

- A page of blank cards if you wish to extend the learning by having students create MORE examples that go in each category. This is a great way to differentiate for more capable learners! See each sort for other differentiation hints!

- No answer key. Why? The important part about doing these sorts is the discussion rather than making sure every answer is instantly correct. Let the students discuss, prove their ideas, and develop understanding!

You may be familiar with my concept sort SETS which each include FIVE different sorts on a topic…from fractions to multiplication to algebra thinking to geometry. These “single sorts” are NOT the same sorts that are included in the sort sets…they are additional sorts that might meet the needs of your students.

I hope you find the resource thorough, relevant, and engaging--and that it will push your students to increase the depth of their understanding and their mathematical practices as well.
