This game helps students learn the "partners of ten." Two players each use a different colored marker. The first player rolls a decahedron (ten-sided) die. The player announces the number and names the addend that goes with this number to make the sum of ten. The player draws a semi-circle from one addend to the other addend. Players take turns rolling the die and drawing parts of the rainbow. If a number is rolled that has already been used, the player misses her turn. Play continues until all of the numbers are part of the rainbow. The winner is the player with the most semi-circles in the rainbow.
