SMARTdeck. Practicing Mental Addition is a card game intended to improve and practice the addition of numbers mentally. This exercise requires mental addition while remembering the sums until deriving the final result.
HOW TO PLAY:
1. Ask someone to think of of a number beetween 1-31, and not to say the number. For example, it could be a birthday or another significant date.
2. Show each card one by one, asking: Is the number here?
3. When the answer is YES, add the top left number of the indentified cards.
Example: Number thought 27
Cards identified: Card #1, Card #2, Card #4 and Card #5
Adding the top left number of the identified cards: 1 + 2 + 8 + 16 = 27
27 is the number thought (the answer).
