Quickly recognizing sums of ten makes addition much easier. This game is simple to learn and uses only basic classroom supplies. It can also be played by four or more players, but more time is spent waiting for each turn. It's the perfect addition to a math center or to use as a quick fill-in for the last few minutes of a class.
I print copies of the game and answer key on front and back of colored pages, and provide scrap paper for score-keeping.
