ADDATTACK by Learning Advantage
Add Attack can be played using the inverse processes of addition and subtraction to gain fluency in both addition and subtraction facts. In Add Attack players use a spinner to generate addends and place colored markers on the sums found on the game board grid. In Sub Attack they spin for a target number then decompose numbers into subtrahends and minuends (or addends). The first player to gain 25 Add Attack points, or fill the Sub Attack Chart, is the winner. Covers sums to 18. Two players or teams.
