IN COLLECTION

Prior to beginning the lesson: (1) Photocopy the **Problem of the Day** onto transparency paper for the overhead projector; (2) Cut out 6” squares of construction paper (10 per student)

**Group Size:** Whole class

**Learning Objectives:**

Students will be able to:

- Identify Numerator and Denominator.
- Identify and write fractions 1/2, 1/4, 1/6, 1/8, 2/4, 2/6, 2/8, 3/4, 3/6, 3/8.

**Problem of the Day** (see attachment), construction paper, crayons, overhead projector

**Procedures:**

Lesson Introduction: Display **Problem of the Day** on the overhead projector. Ask students: *What strategy should we use to solve this problem?* Guide them towards draw a picture. Solve the problem together as a class. Students can copy problem and solution into math notebooks.

- Distribute construction paper squares and crayons to students.
- Tell students:
*Put your paper squares in the corner of your desk. Choose one square to use first and put it in front of you.* - Give students directions:
*Fold your paper in half. What fraction is this?*Give students time to answer. Then direct students to color in one-half and label that part “1/2”. - Tell students:
*Now that we have made one-half, let’s make another fraction. Put another piece of paper in front of you. Fold it in half. Then fold it in half again.*Teacher should demonstrate. Ask students:*What fraction is this?*Give students time to answer. Then direct students to color in one-fourth and label that part “1/4”. Ask students:*What is the numerator? What is the denominator?* - Continue with the same directions and questions for the remainder of eight squares of construction paper, using the fractions 1/6, 1/8, 2/4, 2/6, 2/8, 3/4, 3/6, and 3/8.
- As students color and write each fraction, ask:
*What is the numerator? What is the denominator?*

**Assessment:**

Teacher should monitor student participation and independent work to ensure all students understand the concept.

**Benchmark or Standards:**

National Council of Teachers of Mathematics (NCTM) Number and Operations Standard:

- Develop a sense of whole numbers and represent and use them in flexible ways, including relating, composing, and decomposing numbers.
- Understand and represent commonly used fractions, such as 1/4, 1/3, and 1/2.

- Communicate their mathematical thinking coherently and clearly to peers, teachers, and others.
