### Lesson plan

# Fraction Action: Rectangles

#### Learning Objectives

Students will be able to compare fractions with like denominators with a model to support their thinking.

#### Introduction

*(5 minutes)*

- Gather students together, and review key terms.
- Remind the students that the
**numerator**is the number on top in a fraction, and the**denominator**is on the bottom. Explain that**greater than**means bigger in value while**less than**means smaller in value. - Tell students that they will work on comparing fractions with like denominators.
- Explain that s it is important to note whether the denominators are the same to compare the same whole.

#### Explicit Instruction/Teacher modeling

*(10 minutes)*

- Show students a model of 2 circles. Model dividing both of the circles into 4 equal parts. Shade ¼ and ¾ on the different circles.
- Discuss with students which is greater.
- Show students a third circle. Divide this circle into 3 parts. Shade 1 of the parts. Direct students to compare the circle showing ¼ and 1/3.
- Discuss with students how both have the same numerator but different denominators. Emphasize the importance of looking at the part shaded in view of the whole circle.
- Repeat and continue to discuss this concept using more examples.

#### Guided Practice

*(15 minutes)*

- Give each student a Fraction Rectangles worksheet.
- Have students cut out each large rectangle and shade the amount of parts of their choosing.
- Divide students into pairs. Have students compare the fractions and record the relationship using the signs. For example, if one student colored in 7 and another colored in 3, the students would write:
*7/8 > 3/8*.

#### Independent working time

*(15 minutes)*

- Distribute a second copy of the Fraction Rectangles worksheet.
- Instruct your students to repeat the guided practice activity individually.
- Have students glue rectangles to the construction paper and write the numerals and correct comparison sign between the rectangles.

#### Differentiation

**Enrichment:**Direct students in need of a challenge to compare two fractions with unlike denominators.**Support:**For students in need of support, shade in the rectangles ahead of time instead of allowing the students to choose on their own. Have them identify the numerators.

#### Assessment

*(10 minutes)*

- Show students more examples of fraction models with the same denominator.
- Have students write the correct comparison signs on individual whiteboards to hold up for quick assessments.
- Collect the construction paper with the rectangles to check for mastery.

#### Review and closing

*(5 minutes)*

- Gather students together. Ask several students to share the rectangles they compared.
- Have students read the signs they used in their comparisons.
