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.
Standards:
- 4.CE.2f Determine common factors and the greatest common factor of no more than three numbers.
- 4.CE.3 The student will estimate, represent, solve, and justify solutions to single-step problems, including those in context, using addition and subtraction of fractions (proper, improper, and mixed numbers with like denominators of 2, 3, 4, 5, 6, 8, 10, and 12), with and without models; and solve single-step contextual problems involving multiplication of a whole number (12 or less) and a unit fraction, with models.
Skills:
- Adding and Subtracting Fractions with Like Denominators
- Adding and Subtracting Fractions with Unlike Denominators
- Adding and Subtracting with Mixed Numbers
- Solving Single Step Problems with Adding and Subtracting Fractions
- Simplifying Fractions
- Recognizing and Extending Patterns with Fractions
