Sommaire

Cross out 4 of the 9 stars (2 pts).

The equation is \(9 - 4 = 5\) (1 pt). 5 stars are still shining (1 pt).

a) \(5 - 3 = 2\) (0.5 pt) b) \(4 - 1 = 3\) (0.5 pt) c) \(3 - 2 = 1\) (0.5 pt) d) \(5 - 5 = 0\) (0.5 pt)

e) \(2 - 0 = 2\) (0.5 pt) f) \(4 - 2 = 2\) (0.5 pt) g) \(5 - 1 = 4\) (0.5 pt) h) \(3 - 1 = 2\) (0.5 pt)

a) \(8 - 5 = 3\) (1 pt). 3 cookies are left (1 pt).

b) \(10 - 6 = 4\) (1 pt). Zoe has 4 buttons (1 pt).

a) \(8 - 3 = 5\) (1 pt). The other part is 5 (1 pt).

b) False (0.5 pt): \(7 - 2 = 5\) (0.5 pt).

c) True (1 pt): taking away all 10 leaves nothing.

a) Hop back: 9, 8, 7, 6. You land on 6 (1 pt). \(10 - 4 = 6\) (1 pt).

b) Hop back from 9 to 7: two steps (1 pt). \(9 - 2 = 7\), so the missing number is 2 (1 pt).
