StrategiesStep 2
Split the pizza into 5 equal parts: Now share 5400 equally between the 5 slices – 1080 on each slice.

StrategiesRemove one fifth to leave four fifths:
Add 1080 + 1080 + 1080 + 1080 to find the answer.
• Is one of the two strategies easier?• Might one strategy be better in one situation and the other for a
different problem?

Strategies
Splitting into convenient groups of 4 Counting and shading 1,2,3 and
leaving the 4th un-shaded.

Strategies
Consider though not only shading 3 out of every 4 circles, but also consider shading 3 out of 4 rows

Simplifying fractionsSuppose we want to simplify the fraction
Draw two identical rectangles.Split one into 8 equal parts and the other into 4 equal parts.Shade the same area in each:
8
2
What fraction of the first rectangle is shaded?
What fraction of the second rectangle is shaded?
4

Comparing fractions

Comparing fractionsWould laying the two rectangles over one another help?
