Look around your room. What are the things youfind inside?

4. Developmental Activities

a. Activity 1 Class Activity

Count the number of boys, count the number of girls.

How do you write the comparison of the number of boys to the number of girls using fractional forms?

Is there another way of writing it? How?

3/5

Let the pupils count other objects/things. Let themgive/write the ratio in 2 ways (colon and fractionforms).

Ex. sticks and leaves

batteries and stones

bottle of MD and bottle of Nestea

Did you count the objects/things correctly?

What will you do if you are given objects touse/manipulate? Then, how will you handle them?

b. Activity 2 Problem Solving

o Renz bought 3 pieces of pencils for P10.00 atNational Book Store. Regine bought 6 pieces of pencils for P20.00. Give the ratio of pencils to theamount of money of each child.

Discussion:

a) What did Renz and Regine buy? Howmany pencils did each of them buy?How much did each of them pay?

b) What are being compared in theproblem? Write the ratio in 2 ways.

c) How many ratios did you write?

d) What can you say about the tworatios? Why?

e) How can we write the two ratios toshow equality in two ways?

f) What do you call two equal ratios?

g) Provide other example.

Ex. The ratio of chairs to tablesis 8 to 2 or 4 to 1.
