PRODUCT DESCRIPTION

Show your students some real math magic! Use these binary cards to easily guess ANY number between 1 and 30 that your students choose! Watch as your students are AMAZED by the magic of math!

Instructions:
--Print cards on different colored card stock. Each page should be a different color.
--Have the class secretly agree on a number between 1 and 30.
--Hold up each card (full page of numbers) to the class and they must say "Yes" or "No" if the number they chose is on that card.
--Go through the same process with each page of numbers. There should be 5 total.
--Here's the trick to solve! When looking at each card, remember the TOP LEFT NUMBER (either 1, 2, 4, 8 or 16). Every time your class says "YES" to a card, add the top left numbers together. For example, if the class says "yes" to the first three cards and "No" to the fourth, and "Yes" to the fifth, the secret number is 23 (1+2+4+16)
--It's that simple! Practice a few times before going live in front of your class!
