What is the Magic of Math?

The Magic of Math is a series of math lesson plans and activities that can be used as your math curriculum or as a supplement to the program that you are already using. We provide daily lesson plans, word problems, mini-lesson, activities, and interactive notebook entries. If you don't have time for it all, that's okay too! You can just pick and choose the pieces that you want to incorporate into your math block!

Are these activities repeated in other units you have?

Absolutely NOT! We create all new activities for each Magic of Math unit. They are all unique to this purchase and are not copied/pasted from things we have previously made.

What is the difference between Magic of Math and other units you have?

Magic of Math is organized as daily lesson plans with everything you need rather than just activities.

WHAT IT IS NOT:

It is NOT a collection of worksheets. You will not find any worksheets in this series. Instead, we use games, hands-on activities, engaging mini-lessons, and interactive notebooks to build our curriculum. We do try to keep in mind the amount of prep that is involved with the lessons, but some things will need to be printed, cut, and put together to use in your classroom.
