Product Description
These fun and challenging puzzles make solving for the unknown fun! Four different levels make differentiation super simple. These problems encourage problem solving and critical thinking, skills that are essential for all young mathematicians.

Each level includes the same graphics and the same answers. This way you can check together even if you are using different levels. All cards include addition and subtraction problems within 20. There are 24 cards in each level (a total of 96 different cards). Included: Color cards, black & white cards, answer sheets and an answer key.

These math logic puzzles are different from many that you may have seen because they contain more numbers. This allows for more flexibility in the problems for deeper differentiation.
