Fractions

Lesson

You may have already learned about plotting fractions on a number line. We can use number lines to compare our fractions to some benchmark fractions, including $0$0, $\frac{1}{2}$12 and $1$1 .

Remember!

When plotting fractions on a number line we use:

- the denominator to divide the whole numbers into equal parts
- the numerator to select the number of parts.

Is the fraction $\frac{1}{4}$14 closer to $0$0 or $1$1?

$0$0

A$1$1

B$0$0

A$1$1

B

Is the fraction $\frac{2}{3}$23 closer to $0$0 or $1$1?

$1$1

A$0$0

B$1$1

A$0$0

B

When we have fractions that might have larger denominators, or if we can't easily see where a fraction sits on a number line, there are things we can do still. Watch this video to look at how we can estimate using benchmarks with harder fractions.

Is the fraction $\frac{8}{20}$820 closer to $0$0 or $\frac{1}{2}$12?

$\frac{1}{2}$12

A$0$0

B$\frac{1}{2}$12

A$0$0

Use a range of additive and simple multiplicative strategies with whole numbers, fractions, decimals, and percentages.
