We learned a new Math game called Mindreader! To play, you need three people and a deck of cards.
Two of the people put a card on their forehead so they can't see it and the third person, who can see them both, says the sum of the two cards. You hear the sum and you can see your friend's number. Can you tell what is on your card without looking?
Okay, when you say the number of the card on your head you are not really reading a mind but doing some Math! Try it yourself!
