Guess My Number

Today during Math Time, we learned a new math game that incorporates much of what we've learned about place value.  The game is called Guess My Number and it requires the use of key math vocabulary such as:

• ones, tens, hundreds
• greater than
• less than
• odd 
• even
• columns (on the 100 Chart)
• rows (one the 100 Chart)
• digits

In order to play this game, each player has a 100 Chart. Player #1 thinks of a secret number while Player #2 must ask "Yes or No" questions to determine the secret number. To keep track of the guesses and to organize their thinking, the players track the answers to the questions on the 100 Chart. For example, if my secret number is 22 and my partner asks, "Is your number greater than 15?", my answer would be, "Yes." I would then cross out all the numbers less than 15 on the 100 Chart to help my partner determine my secret number.  This is a great game to play at home!  I will send the directions and materials in next week's homework packet.  Check out our "Guess My Number" chart and some photos of second graders playing the game.
