Learning Objective:

LO: I can use diagrams to find equivalent fractions .

What are equivalent fractions?

Equivalent fractions are fractions with the same value.

Sometimes it is very difficult to find equivalent fractions because the digits used in the

fractions are completely different.

12

is the same as 36

Can you see how all the digits

are different?

Shapes can be used to show two or more fractions are equivalent.

What do you notice?

Although the digits are different the amount of shaded area is the same for both fractions.

Identify the fractions that are equivalent.
