Subtraction Memory (3 sets)
ACMNA015 MA1-5NA For 2 students per game. In this memory game the cards are laid out in rows and columns. In turn players flip over two cards and if they are lucky enough to flip over a subtraction sum on one card and the answer to that sum on the other, they keep the cards. Another player should check the pair is correct using the checking card included with the instructions. Hint - Players could "count on" from the smaller number to find the answer and check their answer by adding it to the second number in the subtraction sentence. e.g. 9 - 5 = 4; 4 + 5 = 9. 3 sets of 40 cards and a checking card.
