What’s My Number? - Game

Number Formation Version

• Each person playing needs a whiteboard or a scrap piece of paper and a marker.

• The person giving the clue should pick a number and write it to describe the way they wrote the number. (They can be described using the number formation rhymes in the songs page.)

• The guesser should then try and write the number they heard described.

• They both should flip their pages at the same time so they can see if the guesser was correct or not.

Number Riddles

• One person should describe a number

  • Describe your number as odd/even, give the number of digits, a span of digits your number is within, and/or the sum of all your number’s digits.

• Then the guesser can write out their guesses and work through it.

• Eventually they should guess a number and the prompter can tell them if they are right or wrong.

• Ex: I’m an even number between 20-50. The sum of my digits is 7. What number could I be?

Place Value Riddles

• In this version, you describe the number by the digits in each of the place values.

• Describe what number is in each place, how many of each place you have.

• Ask the guesser what your number is and see if they got it right.

• For example:

  • I’m thinking of a number with a 7 in the hundreds place, 4 tens, and 3 ones. What number am I thinking of?

  • My number has 14 tens and 2 ones. What is my number?

Digits and Place

• One player thinks of a number that is recognizable for their partner. (It should be 2-3 digits)

• When the prompter is ready they say how many digits are in the number.

• Then the guesser can pick any number with that number of digits.

• Once they make a guess, the prompter tells them how many digits were right, and if any of the place values were right.

• For example, if the number was 45, the game may look like this:

  • The guesser said: 20 - They got 0 digits and 0 places

  • The guesser said: 15 - They got 1 digit and 1 place

  • The guesser said: 35 - They got 1 digit and one place

  • The guesser says: 64 - They got 1 digit and 0 places

  • The guesser says 45 - They got 2 digits and 2 places, they got the number!

Tip: do not pick a number with a repeated digit and keep them between 2-3 digits!
