Relationships and Change - Week 47 - Lesson 1 - Introduction to Ratios

Objective (Teaching Point):

  • Introduction to ratios

  • Equivalent Ratios

  • Simplifying ratios

Lesson:

  • Discuss with the students why we use ratios in real life.

  • To begin, students must have a basic understanding of ratios.  The lesson allows students to interact and to create visuals which match ratios, see the three formats for writing a ratio, and an introduction to equivalent ratios and unit rate.


See the PDF files below.


Equivalent ratios:

Find equivalent ratios:

2 : 7

10 : 4

4 : 14

1 : 3

20 : 8

10 : 30

1 : 3,5

4 : 12

7 : 2


Simplifying Ratios: The process of finding the simplest form of a ratio is the same as the process of finding the simplest form of a fraction.


Example

5 : 10      5 can be divided into both numbers (numerator & denominator)

1:2          This is the simplified ratio in the prefered format.


Simplify the following ratios:

4 : 8

5 : 20

9 : 45

25 : 40

8 : 36

6 : 21

11 : 44



Equivalent ratios:

Complete the following ratios:

1 : 3 = 4 : x

1 : 5 = 5 : x

1 : 4 = x : 20

2 : 5 = 8 : x

5 : 4 = x : 24

4 : 6 = 6 : x ( Can you suggest another way of dealing with this ratio?)


Support:

  • To support students remind them how to simplify fractions and find equivalent fractions.
