🔍 The Guess My Number Game
Ask smart questions and crack the code!
How It Works — Step by Step
Pick a Secret Number
One player picks a number from 1 to 100 and writes it down secretly. The other player will try to guess it!
Ask Yes-or-No Questions
You get 6 questions to narrow it down. Ask things like: 'Is it even?' 'Is it a double-digit number?' 'Is it less than 50?'
Cross Out Numbers on the Hundreds Chart
After each answer, cross out all the numbers that are eliminated. Watch your options shrink with every smart question!
Make Your Guess!
After 6 questions, look at what's left and make your best guess. The fewer numbers remaining, the better your chances!
🎯 42!
Mr. Aube's Tip:
This game builds number sense — kids learn about odd/even, greater than/less than, place value, and logical thinking all at once! The best part? They're having so much fun they don't even realize how much math they're doing.
