## Fractions and Equivalents

### Jeannel LopezColleges and Universities - Florida

#### Description

The students uses Lego blocks, drawing paper, and visual aids to understand the meaning of fractions and the concept of equivalent proportions.

#### Objectives

The student identifies equivalent forms of numbers.

#### Materials

-Lego blocks
-Drawing paper
-Crayons
-Transparency sheets

#### Preparations

1. Prepare a list of fractions to use with the lesson.
2. Set up the overhead projector.
3. Sort the Lego blocks by color to facilitate distribution.

#### Procedures

Note: This lesson addresses equivalent forms of numbers using fractions.

1. Introduce the concept of fractions.

2. Provide examples that reflect fractions relating to real-life situations and how various proportions are equivalent to each other.

3. Split the class into groups.

4. Distribute Lego blocks and advise students that the blocks will be used to create models that are the equivalent of what is shown on the overhead.

5. Introduce the red blocks as the numerator and the blue blocks as the denominator.

6. As a second activity, ask each group to produce four models that are equivalent to each other.

7. Each group is to then use the drawing papers and crayons to record the fractions created on a log and draw a diagram depicting each model.

8. Ask each group to share with the class their models and drawings.

#### Assessments

Students will be formatively assessed during the group activities. The instructor should observe the following:
1. Ensure that the representations created by the groups parallel your examples.
2. Ensure that all students are contributing to group activity.
3. Visit each group and review their logs and drawings; check for accuracy of equivalents.
4. During sharing time, ask each group member to provide an observation made during the activity.
