Tie into what they already know! Use money to teach fractions in this engaging lesson.

### Learning Objectives

Students will understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts by using what they already know about the value of coins compared to the value of a dollar.

## Lesson

### Introduction (5 minutes)

• Review with students by asking for volunteers to share what they remember about coins.
• Tell the students that today they will be dividing dollars into fractions using the coins they have just discussed.
• Remind students that a quarter is worth 25 cents, a half-dollar is worth 50 cents, and that the value of two quarters is equivalent, or equal to, one half-dollar.

### Explicit Instruction/Teacher Modeling (5 minutes)

• Divide students into groups.
• Hand out the Fraction Dollar worksheet to students.
• Explain that the nickel, dime, and quarter are represented below the dollar in the worksheet.
• Have students count together for each denomination (sequence count by 5, 10, and 25).
• Tell the students that the class will complete a larger example of these fractions using the sentence strips.
• Remind your students that the numerator is the top number in a fraction, and the denominator is the bottom number.

### Guided Practice/Interactive Modeling (10 minutes)

• Start with the quarter, and ask guided questions for students to work on as a whole group. Potential discussion questions include: How many quarters does it take to make a dollar? How many pieces would a dollar be divided into? What value would each unit have? If a unit is a fourth, how much would one quarter be?
• Have a volunteer cut out four quarters and paste them evenly on the sentence strip. Then, have that volunteer draw lines to show the ΒΌ pieces on the sentence strip.
• Repeat the same procedure for the dime (1/10th pieces) and the nickel (1/20th pieces).
• Explain to the students that each coin row on their worksheet is the same as one of these sentence strips. Explain that it takes four quarters to make a dollar, so a quarter is 1/4th of a dollar. Do the same with the nickel and dime.

### Independent Working Time (15 minutes)

• Pass out the needed materials for the Dollar Game to each group.
• Read the instructions to students, and have them play this game for two to three rounds.

## Extend

### Differentiation

• Enrichment: Give students the Enrichment Assessment.
• Support: Give students the Support Assessment.

## Review

### Assessment (5 minutes)

• Have students complete the appropriate leveled Assessment Challenge.

### Review and Closing (5 minutes)

• Begin a discussion about the similarities your students found with the sentence strips and what they drew.
• Encourage students to reflect on any changes they might want to make to their Assessment Challenges.
