This product includes 154 addition fact labels (facts 0 thru 12) to use to create a Fact Tower math center. Teachers attach the fact labels to the sides of dixie cups, and write the sums to the facts inside the cups. Students work in pairs or in groups saying the answers (while the pairs check). If a student gets the answer correct, the cup is placed in a line to begin the formation of a tower. If not, the cup goes back in the stack. If the tower falls during the game, the team must start over.
