You have shown class answers with tallies and with pictures. Today we use bars instead. Each answer gets one bar, and we read how high it climbs on the numbered side.
Here is the fruit survey from our pictogram lesson, drawn as bars. Which bar is the tallest? What does that tell us?
Here are two bar charts. Look at the numbered side on the left, and at where every bar begins.
The numbered side is called the scale. You read the number where the top of the bar stops. The Apple bar reaches 6, and the Banana bar reaches 4.
Notice that both bars start on the same base line. That is what lets us compare them fairly.
Here are the votes from a fruit survey: Apple 5, Banana 3 and Orange 4.
Drag each bar up until its top sits on the right number. We check the height before the next bar.
In your maths copy, draw a base line and write the numbers 0 to 5 up the side. Then draw one bar whose top sits on 4.
Four charts to build, one at a time. Read the votes above the chart, then drag each bar up until its top sits on the right number and press Check.
On the last chart, say which bar will be tallest before anyone drags.
