MAT-04.NF.02

MAT-04 Targeted Standards
(NF) Domain: Number and Operations - Fractions
Cluster: Extend understanding of fraction equivalence and ordering.

MAT-04.NF.02 Comparing Fractions s with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, and < and justify the conclusions, e.g., by using a visual fraction model.

Student Learning Targets:

Knowledge Targets

Reasoning Targets

  • I can compare fractions with different numerators and different denominators.
  • I can understand in order to compare fractions, I need to use the same whole.
  • I can justify and explain why my answer is reasonable.

Skills (Performance) Targets

  • I can use fraction models and pictures to compare fractions.
  • I can order fractions on a number line.
  • I can use the >,<, and = symbols to compare fractions.
