Year 5 Reading Pie Charts

Front

What is a pie chart?

Back

A pie chart is a circular graph that represents data in slices, where each slice shows the proportion of each category relative to the whole.

Front

How do you calculate the percentage of a category in a pie chart?

Back

To calculate the percentage, divide the number of items in that category by the total number of items, then multiply by 100.

Front

If a pie chart represents 40 children and 20 chose summer, what percentage chose summer?

Back

50% (because 20 out of 40 is half, which is 50%).

Front

What does each slice of a pie chart represent?

Back

Each slice represents a category of data and its size shows the proportion of that category compared to the total.

Front

How many degrees are in a full pie chart?

Back

360 degrees.

Front

If 6% of people own fish, how many degrees does that represent in a pie chart?

Back

21.6 degrees (because 6% of 360 degrees is 0.06 * 360 = 21.6).

Front

What is the angle for 25% of a pie chart?

Back

90 degrees (because 25% of 360 degrees is 0.25 * 360 = 90).

Front

How do you find the number of items represented by a slice in a pie chart?

Back

Multiply the percentage of the slice by the total number of items.

Front

If 10 children chose spring out of 40, what fraction represents spring?

Back

1/4 (because 10 out of 40 simplifies to 1/4).

Front

What is the total percentage of all categories in a pie chart?

Back

100% (the total of all slices must equal the whole).
