Students need to make a 5 x 5 Bingo card using numbers from the following list. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 27, 28, 35, 36, 45, 48, 49, 54, 63, 70, 72, 80, 81, 90, 0.32, 0.4, 0.8, 1.2, 1.6, 2.4, 2.5, 3.4, 4.2, 4.8, 5.6, 6.5, 8.4, -9, -8, -4, -2.1, 1/4, 3/4, 1/8, 7/8, 2/7, 3/7, 5/7, and symbols for addition, subtraction, multiplication & division. They may place the numbers and symbols in any position and write free in the center-square. To start the game: The teacher slides the cover strip into place, then shows the class the card and asks what the variable is or which operation would be used to solve the equation. If the student has the answer they cover it or X it out. To win the student must fill a row vertically, horizontally, diagonally, fill four corners, cover all or any other given design. The rules are the same as in a regular Bingo game.
To make the cards:
              Paper strip 
7 + m = 10

                    Paper strip 
9 x 3 = w

View the flash cards I have provided above or create your own. Any mathematical sentence can be written on the front of the equation flash card. Use a strip of paper 3 cm wide and 15 cm long as the cover strip. Fit the strip loosely around the equation flash card and paste or tape the strip together on the back so that it can slide to different positions. Write a variable on the strip as in example above, m and w.
