Question

Sue wrote a double fact. It has a sum less than 10 and greater than 4. The addends are each less than 5. What fact might she have written?

Answer 1

She might have written:
4+4
3+3

5+5 is 10, and the sum has to be lower then 10
2+2 is 4 and the sum has to be higher then 4

Answer 2

The correct answers are:

3+3; and
4+4.

Step-by-step explanation:

Our doubles facts for sums less than 10 are:
0+0 = 0
1+1 = 2
2+2 = 4
3+3 = 6
4+4 = 8

We want the ones that are greater than 4; this leaves 6 and 8, or 3+3 and 4+4.
