Picture Graphs

In a picture graph, each picture stands for a number. Always check the key to know what each picture is worth.

If the key says "Each star = 2," then three stars means 6. A half-star means half the key value, so half a star = 1.

To find a total, count the pictures in a row and multiply by the key value.

Bar Graphs

The taller (or longer) the bar, the larger the number it represents. Each bar sits on a shared number line so you can compare them easily.

Read the number at the top of each bar. To find how many more one category has than another, subtract the smaller bar from the larger one.

Line Plots

A line plot uses a number line with X marks stacked above each value. The more Xs above a number, the more times that value appears in the data.

Line plots work well for measurement data like heights, lengths, or temperatures. You can quickly spot the most common value and see how spread out the data is.

Reading Graphs

When reading any graph, start by checking the title and labels. They tell you what the graph is about and what each axis or row means.

Common questions include finding the most or fewest, adding totals, and comparing two bars or rows to find a difference. Practice these skills with the questions below each graph.
