Mixed-operation word problems

Solve multi-step word problems that combine fraction or decimal multiplication and division with addition or subtraction.

Real problems often need more than one operation in a row. Read the whole problem first, decide what you need to find FIRST, then work step by step, labeling each answer as you go.

Every skill from this unit -- multiplying, dividing, adding, subtracting fractions and decimals -- can show up combined in a single multi-step problem.

📋 For the teacher

Teach it (10–15 min):

Model reading the whole problem once through before writing anything, then underline the final question being asked.
Break multi-step problems into clearly labeled steps ("Step 1," "Step 2") on paper -- this habit prevents stopping too early.
Mix fraction and decimal problems in the same sitting, since real life does not sort them for you ahead of time.
After solving, restate the answer in a full sentence with units, so it is clear the original question was actually answered.

Talk about it:

Why is it important to read the whole problem before starting to compute?
How do labeled steps help on a problem with more than one operation?
How do you know your final answer actually answers the question that was asked?

Mastery looks like: They can break a multi-step fraction or decimal word problem into ordered steps and solve each one accurately.

Common stumbles: Stopping after the first step instead of continuing to the actual question asked; mixing up the order of multiplication and division.
