FAQs

What does this worksheet require students to do?

Fill in the blank in each equation so the left side balances the right side and both sides are equal.

How many problems are included in the answer key?

The answer key lists solutions for 15 balancing-equation items.

Are negative numbers included in the equations?

Yes. Some equations include negative values (for example, results like -6 and -1), and the missing terms must still make both sides balance.
