Subject: Addition and Subtaction with numbers 1-20

[Question]
What is the best way to help my child understand and succeed on 
problems of addition and subtraction on numbers 1-20, without using 
fingers?? She is 6.5 years old.

[Difficulty]
She gets exhausted and sometimes frustrated doing homework on this topic
(up to 6 pages a day sometimes).
On chart problems where the wanted sum is 15, for example, and she 
has to fill in the numbers that are missing horizontally, vertically and 
even diagonally, based on a few given numbers. She has to have my help doing
homework.

[Thoughts]
I taught her to memorize up to 10 (ex: 6+3=9)and then to take 
numbers up to 10 For example:16-7=? : 7+3=10 and then there are 6 from 10 to
16, so 3+6=9 and so the answer is 9. Is this acceptable?

Thank you,
Ilana
