Finding a fraction of an amount
Strategies Strategy 1 Step 1:
Strategies Step 2 Split the pizza into 5 equal parts: Now share 5400 equally between the 5 slices – 1080 on each slice.
Strategies Remove one fifth to leave four fifths: Add 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 fractions Suppose 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: What fraction of the first rectangle is shaded? What fraction of the second rectangle is shaded?
Comparing fractions Would laying the two rectangles over one another help?
