Subtracting Fractions with Like Denominators
By Claire M.
A practice set for 4th graders that builds understanding of subtracting fractions with the same denominator through pizza-slice and bar-model visuals, worked examples, and step-by-step guidance. It works well as a focused lesson or independent practice in a 30 to 45 minute math block.

Teacher Guide & Tips
- Use this as a whole-class mini-lesson by modeling the pizza example with physical fraction strips before students try the bar-model worked example.
- Discussion question: Why does the denominator stay the same when we subtract, and what changes? Ask students to explain using their own pizza or bar model.
- Scaffold for struggling readers: Have them shade the bar model on paper first and count the remaining pieces aloud before writing the numerical subtraction.
- Extension for advanced students: Ask them to create a word problem with a subtraction of like-denominator fractions and to check whether the answer can be simplified.
- Estimated time: About 30 to 45 minutes including the worked examples and a short set of practice problems.
