Upside Down Numbers
471, 174, 129 or 921… Can you read all the hidden numbers?
How do you work out the Mystery Number?
Arrange the hundreds, tens and ones to solve the puzzle.
This is a tactile game to recognise the order of digits in a series of numbers.
Given enough clues, the player will find the 3-digit hidden number.
To understand the numerical values of each column i.e. left column is for hundreds, middle column is for tens etc.
Prepare 2 number-baseplates, one for each player.
On a third baseplate, create 3 columns with sausages of playdough.
Place letters H, T, O at the top of the columns to indicate hundreds, tens and ones. Give that third baseplate to player 2.

Tell player 1 to decide on their Mystery Number: they think of a 3-digit number and write it secretly on their number-baseplate.
Give player 2 a clue: for example: “the tens digit is a 3”.
Tell player 2 to place the number (3) in the correct column on the baseplate.

They ask for more clues until they know the secret number.
If the game is too simple for your students, add columns for thousands and millions!
