How to teach it

Have the student circle the requested part and count the uncircled pictures. Discuss a zero part separately when using that activity.

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.

Start with 7 pictures. Circle 3 of them. Count the pictures outside the circles: 4. The whole is 7, and its two parts are 3 and 4. Together, 3 and 4 make 7.

On the number bond, the number labeled Whole describes every picture. The two connected numbers under Parts describe the circled and uncircled groups. Write the missing part, not the whole again.

Ask your student

Do the two parts still account for every picture?

If your student needs help

If the student counts the whole as the missing part, separate the circled and uncircled groups.

Choosing and using the worksheet

The default activity uses totals from 2 through 9 and two nonempty parts. Choose “One empty part (0)” below for two questions with a given part of zero and two with a missing part of zero. Both activities have four questions and keep totals within 9. Neither includes a whole of 10 or teen numbers. Choose the related making-10 activity when the child is ready to work with a total of ten.

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

Check both groups. Different pictures may be circled as long as the two parts have the right counts and make the pictured whole.
