UNIT 7: Understanding Operations with Fractions and Decimals
In this unit, students will apply their understanding of unit fractions and fraction equivalence to addition and subtraction of fractions. Students will add and subtract fractions including mixed and improper fractions with like denominators. Students will learn how to turn mixed fractions into improper fractions using visual models. Additionally, students will learn how to break improper fractions into mixed numbers by using their understanding of fractions equaling 1 (e.g. 5/3 = 3/3 + 2/3 or 5/3 = 1 + 2/3). Students will apply and extend their understanding of adding fractions by multiplying fractions. Just as students see repeated addition as multiplication students will develop an understanding that all fractions are made up of repeated unit fractions (7/5 = 1/5 + 1/5 + 1/5 + 1/5 + 1/5 +1/5 + 1/5 or 7/5 = 7 x 1/5). Students are expected to use and create visual fraction models to multiply fractions by whole numbers.
Additionally, students will apply their understanding of fractions to decimal equivalence. Decimals are introduced for the first time in 4th grade. Students will make connections between fractions with denominators of 10 and 100 within the place value chart to help add decimals.

UNIT 5: Extend Understanding of Fractions
- Skills to master:
- Create area, length and number line models to compare two fractions.
- Record comparisons of fractions using the <,>,= symbols.
- Reason about the size of fractions using area and length models when making comparisons.
- Compare two fractions with common numerators and common denominators.
- In 4th Grade, the focus is on conceptual understanding of fractions. Students explain WHY a fraction is equivalent to another fraction by using area and length fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. They also compare two fractions with different numerators and different denominators, using denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100, and justify the conclusions by reasoning about their size using models, benchmark fractions, and comparing common numerators and denominators.
- Knowing how to do the "butterfly method" is an excellent way to produce an accurate answer but is not enough to satisfy the grade standards of being able to explain why a fraction is equivalent to another, or larger/small than another. Answers must be accompanied by explanations with words and models.
