8 + 5
- Step 18 + 5: 8 counters in the first ten frame, and 5 more to add.
- Step 28 needs 2 more to make 10. Move 2 of the 5 to fill the first frame.
- Step 35 is 2 and 3, so put the other 3 in the next frame: 10 + 3 = 13.
- Step 48 + 5 = 13. Make 10 first: 8 + 2 = 10, then 10 + 3 = 13.

About this lesson
Making ten (also called bridging ten) splits the second number so the first part makes a ten. For 8 + 5, your child sees that 8 needs 2 more to make 10, splits 5 into 2 and 3, and adds 10 + 3 = 13. Ten frames show the ten filling up; the number line shows the same jumps, and works for bigger numbers too.
What your child learns
- Add by making ten first, such as 8 + 5 = 8 + 2 + 3.
