• When adding with 8, you only need two more to make a ten. Cross out the last two counters from the bottom frame, and move them to the top frame.
• When adding with 8, you only need two more to make a ten. So, look at the other addend and think two less. In the first example, two less than 6 is 4, which is a clue that the sum is 14

### Adding with 7 (Third Easiest)

• When you add with 7, you only need three more to make a ten. Cross out the last three counters from the bottom frame, and move them to the top frame.
• When you add with 7, you only need three more to make a ten. So, look at the other addend and think three less. In the first example, three less than 5 is 2, which is a clue that the sum is 12.
