Grade 4 - Comparing Fractions
Standards covered:
- 4.3 Number and operations
-
4.3C
Determine if two given fractions are equivalent using a variety of methods.
-
4.3D
Compare two fractions with different numerators and different denominators and represent the comparison using the symbols >, =, or <.
The Comparing Fractions Unit involves using a variety of methods to compare two fractions with different numerators and different denominators. Comparison methods may include building models and visually analyzing the fractions they represent; creating common denominators or common numerators; and/or comparing to a benchmark fraction such as ½. Questions to answer may include:
- Why must we use the same “whole” when comparing fractional parts?
- How can you prove that fractions are equivalent when using area models, linear models or set models?
- What benchmarks are useful for comparing two fractions? Why?
