Each Box of Proof! Math Game Includes:

• 100 number cards chosen for optimal fun!
• For a better mental math experience, there are more of the easier-to-use lower numbers, such as 0 - 10.
• We've also removed some of the more difficult-to-use larger numbers, like 85.
• And, we've left out many tricky prime numbers, like 97.

Instructions with game play options, including solo play and modifications for kids of all ages and levels!

• Play with numbers up to only 20, 30, or 50 (you get the idea).
• Play with 12 cards on the table rather than 9.
• Play without multiplication, division, or square roots as needed.
