This is a Halloween math bump game to help students practice their double facts from 4 to 9.
Make dice from foam or wood cubes. Mark the dice with the numbers 4-9. (You could also use a spinner, or number cards with the numbers 4-9 on them.) Give each student 10 markers. (I use linking cubes.) The student rolls the dice and doubles the number. She places a marker on that number. The next player rolls. If he rolls the same number, he can bump the other player's marker off and place his marker. Once a number has 2 of the same color markers, that number is locked. The first player to use all of his/her markers is the winner.
