LC: Visualize division of a fraction by whole number.
Divide whole number by a fraction

I. Learning Objectives: After cooperative learning approach, pupils shall be able to:
C: use models to show division of whole number by a fraction.
P: formulate steps to follow in dividing whole number by a fraction.
P: divide fractions by whole number correctly.
A: work cooperatively with group mates.

II. Learning Content:
Topic: Division of Whole Number by a Fraction
Concept: The whole number (dividend) must be written as a fraction with a denominator one. Determine the reciprocal of the (divisor).
Then, multiply both the numerators and both the
denominators. Express the answer in simplest form if needed.

A. Introduction: Write its reciprocal:

a. 2 1 b. 7 2
4 3

B. Interaction: Activity 1: Dividing Pizza!
Materials: square pizza out of card board, pair of scissors, masking tape, manila paper

Problem: Dan ordered 5 large pepperoni pizzas for his birthday party.
There will be 16 guests at the party. He estimates that each
guest will eat about ¼ of a pizza. Did Dan order enough
pizza?

1. What are the basic facts?
- Dan ordered 5 large pepperoni pizzas
- There are 16 guests in the party.
- What do we need to find out?
- Did than order enough pizza?

· 2.Show through your models on how you divide the pizza.
3. What is the division sentence for the given problem?
4. What conclusion can you make?
- Each pizza contains four 1/4 – pizza servings.
Five pizzas contain 5 times 4, or 20 servings of pizza.
So, Dan will have enough pizza.

Discussion
· How many servings does each pizza contain?
· Will there be enough pizza for all the guests? Why?
· What did you in order to find the answer?

C. Integration:
