Games & Ideas: Maths

Mind Reading

1. Begin this trick by telling your child you can read minds.
2. Ask them to think of any number. Any number will work, but you may want to warn your child that it may be easier for them if she chooses a small or even number.
3. Tell your child to double the number. Add 10. Divide it in half. Then, subtract the original number.
4. Look your child in the eye, make a face like you’re thinking really hard and then say, “Five!” If your child did their math properly, you have just guessed their number!
5. This trick is similar to the card trick in that magic is in the math — the answer will always be the same. Have your child try again with different numbers, writing out the math as she goes, to see how it works.
