Addition fact · near doubles
5 + 6 = 11
Five plus six equals eleven. 5 and 6 are next-door neighbors, so this fact sits right beside a double.
See 5 + 6
5 red and 6 yellow. The first frame fills up at 10, and 1 more sits in the next one.
Use a double, then add 1
- Find the double you know: 5 + 5 = 10.
- 6 is one more than 5, so the answer is one more than 10.
- 10 + 1 = 11, so 5 + 6 = 11.
Prefer going down? 6 + 6 = 12, and 12 − 1 = 11 too.
