Detectives, listen carefully. Here are a class's break-time votes as a tally. We can also show the same votes as pictures, or as bars.
Which way do you think is quickest to read, and why?
Here are the same break-time votes three ways. For each chart, name the winner out loud before we move on.
Did every chart name the same winner?
Today we build a pictogram from this tally. One picture stands for two votes, so each press of + adds half a picture.
Apple has 6 votes. Each picture is 2 votes. Count 2, 4, 6. That is 3 pictures for Apple.
How many pictures do Banana, Orange and Grapes need? Build the four rows together.
In your maths copy, write which way of showing data you find easiest to read.
Here are the votes for favourite season: Spring 6, Summer 12, Autumn 8 and Winter 4.
First build the four bars. Then find the tallest bar and the shortest bar, and type how many votes each got. Last, work out how many more votes Summer has than Winter.
