What is subtraction?: Taking a number away from another to find out how many are left
What does the − sign mean?: Minus — it means take away or subtract
What is a difference?: The answer to a subtraction problem. In 8 - 3 = 5, the difference is 5
5 - 2 = ?: 3
7 - 4 = ?: 3
10 - 3 = ?: 7
6 - 6 = ?: 0 — any number minus itself equals zero
9 - 5 = ?: 4
8 - 0 = ?: 8 — subtracting zero leaves the number the same
Count-back strategy: 10 - 3 = ?: Start at 10, count back 3: '9, 8, 7' — the answer is 7
If 4 + 6 = 10, what does 10 - 6 = ?: 4 — addition and subtraction are opposites that undo each other
