Cut out and use the digits and symbols to make math expressions that equal the numbers from 1 to 100. Example: (1 + 9) x 9 + 9.
1999 Manipulatives
Rules of the Game: Use only the digits 1, 9, 9, and 9, in any order, with the operations +, -, x, ÷, ^(raised to a power), sqrt(square root), and !(factorial), to write expressions for the counting numbers 1 through 100. Grouping symbols may also be used, but two-digit numbers such as 19, 91, 99 may NOT be used. Write your answers without using equal signs.

Correct format: (1 + 9) x 9 + 9
Incorrect format: 1 + 9 = 10 x 9 = 90 + 9 = 99
