How to teach it

Build the known part, then add counters until there are ten. Match the newly added group to the blank.

Example to work through together

Use the model below as you explain the example. Have your student point to the quantities as you discuss them.

Keep the eight counters together. Add one counter and say “nine.” Add one more and say “ten.” Two counters were added, so 8 + 2 = 10.

The 10 is already the total. The box asks for the missing part. To check, count all eight original counters and the two new counters together.

Ask your student

What number makes this equation true?

If your student needs help

If the student adds the printed numbers, point to ten as the total already given.

Make a practice set

Select the worksheet, answer key, or both. When both are selected, the answer key prints after the questions. Keep it separate if you want your student to work independently.

Print materials

After your student finishes

Read each completed equation aloud. Count both parts to check that they make 10. The missing number tells how many were added.
