Subtracting Decimals to Hundredths with Grids
A printable practice set of 20 decimal subtraction problems for 5th graders, where students shade 10x10 grids to model each difference before writing the final answer. It builds place-value understanding and fluency with subtracting decimals to the hundredths, and it includes worked examples and hints such as rewriting 0.8 as 0.80. It works well as independent practice or a station activity following a grid-model lesson.
Teacher Guide & Tips
- Introduce the method first: shade the starting amount on one grid, cross out the amount to subtract on a second grid, and count what remains, then connect the count back to the decimal answer.
- Discussion question: Why does 0.8 - 0.35 need the 0.8 written as 0.80 before subtracting, and what would the grid show if we skipped that step?
- Scaffold for struggling readers: have students complete the first two problems together with you, narrating each shading step aloud, and provide blank 10x10 grids they can reuse before moving to independent work.
- Extension for advanced students: ask them to create their own problem that requires regrouping across the tenths and hundredths places, then model it with grids and explain why the answer is correct.
- Estimated time: about 25 to 30 minutes for all 20 problems, or 10 to 15 minutes if you assign only the first ten.
