llen has 14 carrots.

He eats 9 carrots.

How many carrots does Allen have left?

Choose the answer that shows how to make 10 to solve.

• 9 + 2 = 11, 11 + 4 = 15, 9 + 2 + 4 = 15, so 15 – 9 = 6

• 9 + 1 = 10, 10 + 4 = 14, 9 + 1 + 4 = 14, so 14 – 9 = 5

• 9 + 1 = 10, 10 + 4 = 14, 9 + 1 + 4 = 14, so 14 – 4 = 10

• 8 + 2 = 10, 10 + 5 = 15, 8 + 2 + 5 = 15, so 14 – 9 = 5
