Draw a grid on a sheet of butcher paper or a piece of poster board, using a straight edge and a fine-tipped marker. Use the amount of boxes equal to the amount of numbers you are teaching. For example, if you are teaching the numbers 1 through 10, draw a grid that has 10 boxes. Each of the boxes should be about 5 inches by 5 inches.
Print a number inside each of the boxes. Use a thick-tipped marker in a color that is easy to read, such as black, red or blue. Print the numbers in numerical order or in a jumbled up order; the order in which you print the numbers does not matter.
Clear floor space in your classroom. The area should be large enough to hold your grid and a piece of masking tape 4 feet away from it. The area should be free from items that students can potentially bang their arms into while playing the game.
Lay the grid on the floor. Secure it to the floor by placing clear tape over each of the corners of the butcher paper or poster board; the tape should run across the grid and touch the floor. Run a piece of masking or duct tape on the floor about 4 feet away from the end of the grid. This piece of tape will serve as the point on which students must stand while playing the game.
Provide students with beanbags. Have one student at a time stand on the tape line and toss her beanbag onto the grid. The student must state the name of the number that her beanbag lands on. Play non-competitively, or if you want to make the game a competition, award points to students who correctly identify the name of the number; the student who earns the most points wins the game.
