Grade 4 Unit 7 Fraction Part 2
Unit 7 Fraction Part 2
Content Emphasis/ Big Ideas
In this unit, students apply the fraction understandings they gained in the first fraction unit to adding and subtracting with fractions. Students also use their knowledge of common multiples and factors from earlier units to simplify fractions and find equivalent fractions. Students expand their understanding of the properties and equality to include operations with fractions.

- MTH.G4.5.a Determine common multiples and factors, including least common multiple and greatest common factor. (PRS 2)
- MTH.4.5.b Add and subtract fractions and mixed numbers having like and unlike denominators. (PRS 2)
- MTH.4.5.c Solve single-step practical problems involving addition and subtraction with fractions and mixed numbers. (PRS 2)
- MTH.4.15 Identify, describe, create, and extend patterns found in objects, pictures, numbers, and tables (numerical). (PRS 6)
- MTH.4.16 Recognize and demonstrate the meaning of equality in an equation. (PRS 6)
