About this worksheet
A free printable find the missing weight to balance the scale worksheet with an answer key. Both sides weigh the same. What number goes on the empty weight? Write it in the box. First graders can do it on their own once they know the strategy at the top of the page. Have your child say each fact out loud while writing the answer.
Tips for using it
- Use small objects like buttons or cereal to check tricky problems.
- Before each scale, ask: which side went down? That side is heavier, every time.
- On the missing-weight pages, add up the full side first, then ask how much the other side still needs.
- For the shape puzzles, always solve the scale with only one kind of shape first.
Printing tips
Download the PDF and print at 100% (or “fit to page” on A4). Page 1 is the worksheet and page 2 is the answer key with the answers in red; print just page 1 if you want to keep the answers for checking. The PNG shows page 1 only. Free for personal, family and classroom use.
