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)
Students will be able to:
Problem of the Day
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.
(see attachment), construction paper, crayons, overhead projector
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?
Modifications: For students with special needs, teacher can assist with folding the paper as necessary.
Teacher should monitor student participation and independent work to ensure all students understand the concept.
