Subtraction with Bar Models for Grade 4
By Angela E.
A practice set of multi-digit subtraction word problems for 4th graders, using bar (tape) diagrams to represent totals, known parts, and unknown parts. It builds regrouping fluency and the habit of modeling before computing, and works well as a focused independent or partner practice block.
Customize for your classroom
Teacher Guide & Tips
- Use as a 20-30 minute independent or partner practice after a mini-lesson on drawing bar models for subtraction word problems.
- Discussion question: How does drawing the total and the known part help you decide what the unknown part is before you calculate?
- Scaffold for struggling readers: Have students underline the total and the amount taken away in each problem, then sketch the bar before writing any equation.
- Extension for advanced students: Ask them to write their own word problem with a three-digit total and a regrouping step, then exchange it with a partner to model.
- Estimated time: About 5 minutes per problem, so plan roughly 25 minutes for a full set.
