Your students will love this math number trick. Students will ask a person to think of any number between 1 and 15. It will appear as though they are reading someone's mind and to do the trick all they need to do is mentally add up any combination of the numbers 1,2,4 and 8.
This would work great when you teach students how to mentally add numbers up to 20 which is Common Core Standard 2.OA.2)
It's a simplified version of a famous trick which goes from 1 to 31.
Note: All 4 cards are included when you purchase the product.
