Part 1

Use your fraction circles to model $\frac{3}{8}\:and\:\frac{5}{8}$.

Who ate the most?

Are each of the pieces in the models the same?

• Yes.  They have the same denominators.  The whole is shared equally among 8 sections.

How many pieces are used to model $\frac{3}{8}$?

• Three

How many pieces are used to model $\frac{5}{8}$?

• Five

Which fraction is larger?

• $\frac{5}{8}$

How do you know?

• $\frac{3}{8}\:and\:\frac{5}{8}$have the same size pieces of the whole, but $\frac{5}{8}$has 5 pieces.

If each model represented slices of your favorite treat, which model would you rather have and why?

• $\frac{5}{8}$, because it is the larger quantity.

The symbol < means "less than".  The symbol > means "greater than". The symbol = means "equal to".

What symbol would be placed between $\frac{3}{8}$and $\frac{5}{8}$?

• <
• $\frac{3}{8}$< $\frac{5}{8}$

Let's compare some other fractions with the same denominators.

a) $\frac{2}{3}$ $\frac{4}{3}$

• $\frac{2}{3}$ <  $\frac{4}{3}$

b) $\frac{2}{2}$ $\frac{5}{2}$

• $\frac{2}{2}$ <  $\frac{5}{2}$

c) $\frac{5}{6}$ $\frac{1}{6}$

• $\frac{5}{6}$ > $\frac{1}{6}$

Part 3

Play media comment.

What are the fractions?

• $\frac{2}{6}$and $\frac{4}{6}$

Which fraction is larger?

• $\frac{4}{6}$

What is a sentence we could write to compare the fractions?

• $\frac{2}{6}$< $\frac{4}{6}$or $\frac{4}{6}$>$\frac{2}{6}$

Part 4

• Playing sports takes more time.

What is a sentence we could write to compare the fractions?

• $\frac{3}{8}$> $\frac{2}{8}$or  $\frac{2}{8}$<$\frac{3}{8}$
