Twelve subtraction equations, and the child circles true or false for each one. Some are right (9 − 4 = 5) and some are wrong (12 − 6 = 5), and they split evenly, six and six.
Several of them are written the other way round (8 = 10 − 2) or have math on both sides (10 − 3 = 3 + 4). That is on purpose: first graders often think the equal sign means “the answer comes next,” and these show it really means “the same as.”
Watch 9 − 9 = 1 and 7 − 0 = 0. They look almost right, which is exactly why they are there.
