How Many More? Word Problems Within 20

Teaching notes for parents and teachers

How to teach it

Build the starting amount and add counters until the target is reached. Count only the newly added counters.

Ask your student

Which counters tell us how many more were needed?

If your student needs help

If the student gives the target as the answer, separate the starting counters from those added.

Choosing and using the worksheet

Each set contains four questions with positive additions and targets within twenty. In each strip, the filled spaces show the start and the empty spaces show room left before reaching the target. Shade the extra spaces, write an equation, and record the amount added. The answer key colors those extra spaces separately.

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.

After your student finishes

Cover the answer and have the child name the start, the added amount, and the target. Check that start plus added equals target. Accept a correct addition or subtraction equation that describes the same relationship.
