(2) developing an understanding of fraction equivalence, addition and subtraction of fractions with like. Step 2: Shade in more than one-time fractional unit. Explanation: In the above-given question, given that, 3 tenths 3/10. In Grade 4, instructional time should focus on three critical areas: (1) developing understanding and fluency with multi-digit multiplication, and developing understanding of dividing to find quotients involving multi-digit dividends. Step 1: Draw an range model for a fraction with who denominator of 3, 4, or 5. Express the equivalence of tenths and hundredths with fractions and with decimals. Lessons 20–21: Use visual models to add two fractions with related units using the denominators 2, 3, 4, 5, 6, 8, 10, and 12. Decompose tenths into hundredths using the area model. Lesson 19: Solve word problems involving addition and subtraction of fractions. Lesson 18: Add and subtract more than two fractions. Lesson 17: Use visual models to add and subtract two fractions with the same units, including subtracting from one whole. Lesson 16: Use visual models to add and subtract two fractions with the same units. Lessons 14–15: Find common units or number of units to compare two fractions. Lessons 12–13: Reason using benchmarks to compare two fractions on the number line. Lesson 11: Explain fraction equivalence using a tape diagram and the number line, and relate that to the use of multiplication and division Lessons 9–10: Use the area model and division to show the equivalence of two fractions. Lesson 6: Decompose fractions using area models to show equivalence.įraction Equivalence Using Multiplication and Division Lessons 7–8: Use the area model and multiplication to show the equivalence of two fractions. Lesson 5: Decompose unit fractions using area models to show equivalence. Lesson 4: Decompose fractions into sums of smaller unit fractions using tape diagrams. Lesson 3: Decompose non-unit fractions and represent them as a whole number times a unit fraction using tape diagrams. Lessons 1–2: Decompose fractions as a sum of unit fractions using tape diagrams. Grade 4 Math: Grade 4, Module 5, Lesson 5: Decompose unit fractions using area models to show equivalence.
