IN COLLECTION

Prior to beginning the lesson: (1) Photocopy the **Problem of the Day** onto transparency paper for the overhead projector; (2) Cut out and laminate **Vocabulary Cards** for display in the clasroom; (3) Photocopy **Clay Fractions Activity Sheet** (1 per student).

**Group Size:** Partners

**Learning Objectives:**

Students will be able to:

- Identify Numerator and Denominator.
- Identify and write fractions 1/2, 1/3, 1/4, 1/6, 1/8, and 1/10.

**Problem of the Day** (see attachment), **Clay Fractions Activity Sheet** (see attachment), **Vocabulary Cards** (see attachment), overhead projector, clay or Play-Doh, toothpicks (1 per 2 students)

**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.

- Divide students into partners. Within each partner group, designate a Partner 1 and a Partner 2. Explain to students they should assist their partner when it is not their turn to solve the problem.
- Display
**Vocabulary Cards****Fraction**,**Numerator**, and**Denominator**on the board. - Distribute a handful of clay and a toothpick to each group. Instruct students to shape clay into a flat square.
- Tell students:
*Now I want you to divide your clay into half.*Ask students:*What is the fraction?*Call on one student to write "1/2" on the board. Tell students:*Use your toothpick to write one-half on each piece of your clay.*Now ask students:*What is the numerator? What is the denominator?* - Remind students to switch partners and tell them:
*Next make a flat circle with your clay.*Then repeat the same question sequence with one-third. - Remind students to switch partners and thell them:
*Make a flat square again with your clay.*Repeat the same question sequence for one-fourth. - Continuing with a square shape, repeat the same procedure with one-sixth, one-eighth, and one-tenth.
- Collect clay and toothpicks from students and distribute
**Clay Fractions Activity Sheet**. Instruct students to work with their partner to draw the fractions they just modeled with their clay.

**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.
