How does knowing 5 + 5 = 10 help you solve the combo fact 5 + 6?
Model Student Explanation (6 points):
"6 is exactly 1 more than 5. So, I can start with 5 + 5 which is 10, and then just add 1 more to get 11. It's like doubling 5 and adding 1 more: 10 + 1 = 11."
⭐️ 3 pts: States 6 is 1 more than 5 ⭐️ 3 pts: Explains adding 1 to the sum of 10
