Partitioning and Unit Fractions Practice for Grade 3
By Jillian A.
A practice set for 3rd graders that introduces unit fractions through partitioning wholes into equal parts, such as splitting a pizza among friends. It builds understanding of the numerator and denominator, supported by key-term definitions, a worked example, and fraction models, and it works through multi-step problems with worked solutions aligned to CCSS 3.NF.A.1.
Customize for your classroom
Teacher Guide & Tips
- Use this as a math block lesson or independent practice after students have seen simple shape partitioning, pairing the pizza worked example with physical paper folding so students can see the parts.
- Discussion question: If you split a pizza into 4 equal parts, why is each piece called one-fourth, and what would change if you split it into 8 parts?
- Scaffold for struggling readers: have students shade one part of a fraction model first and say the numerator and denominator aloud before attempting the multi-step problems.
- Extension for advanced students: ask them to explain why a unit fraction always has a 1 on top and to create a partitioned shape for a fraction like 1/6 and describe it.
- Estimated time: about 30 to 45 minutes, depending on how many practice problems you assign.
