#### MAT-05.NF.02

 MAT-05 Targeted Standards(NF) Domain: Number and Operations - FractionsCluster: Use equivalent fractions as a strategy to add and subtract fractions. MAT-05.NF.02 Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers.

## Student Learning Targets:

### Reasoning Targets

• I can use what I know about benchmark fractions to decide if my answer is reasonable.
• I can use what I know about benchmark fractions to estimate mentally.

### Skills (Performance) Targets

• I can solve word problems that involve fractions with like denominators.
• I can solve word problems that involve mixed numbers with like denominators.
• I can solve word problems that involve fractions and mixed numbers with unlike denominators.
• I can use visual models or equations to represent my reasoning.
