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 the daily lesson plans, word problem, mini-lesson, activity, and interactive notebook entries for four weeks at a time. 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 repeats from 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 copy/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.


It is NOT a collection of worksheets. 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.

to see state-specific standards (only available in the US).
Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
Apply properties of operations as strategies to add and subtract. If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = ▯ - 3, 6 + 6 = ▯.
