This sheet presumes making number into 10 helps make adding easier
2. 8 + 5 =
10 + 3 = 13 we get 3 by taking 2 from 5 and giving it to the 8 to get 10
3. 8 + 6 =
10 + 4 = 14 take 2 from 6 to give to 8 to make 10
I suspect the purpose of this is to promote mental math
Answer:
I'm going to explain this by doing number 2.
Step-by-step explanation:
Okay, so 8 is 2 away from 10. So we subtract 2 from 5, leaving 3. We add the 2 to the 8, making 10. Now, we add the other 3. 10+3=13. 8+5=13.
