Product Description
Amaze your students with the "Magic Number Cards" that uses the binary number system in order for the teacher to correctly guess a student's secret number. Students will think it's magic and you'll know the secret. This product will be popular in your classroom and best of all...it's free!

1. Have the student pick a secret number from 1-63.
2. Tell the student to look at the six number cards and to only give you the number cards that has his or her secret number on them.
3. Figure out his or her secret number by adding all the first numbers located in the upper left hand corner of each card that is given to you by the student. For example, if the student gives you two cards and the first numbers on each card are 16 and 8, then 16 + 8 = 24...so their secret number is 24!
