Children's favourite fruit votes (apple 5, banana 3, grapes 6) are recorded in a tally table, and then each tally mark changes into one picture of a pictograph and each picture into one square of a bar graph, with the totals counted and checked at every step. The video ends with all three side by side, lighting up one mark, one picture and one square together to show that each stands for one child.

Transcript

What the lesson says

Each child picked a favourite fruit: apple, banana or grapes.

In a tally table, each mark stands for one child.

We draw the fifth mark across the first four.

Count the marks: five for apple, three for banana and six for grapes.

Now let's show the same data as a pictograph.

Each tally mark becomes one picture.

The key says one picture stands for one child.

Count the pictures: still five, three and six.

Next, let's show the same data as a bar graph.

Each picture becomes one square.

Add a number scale along the bottom.

The bars end at five, three and six.

The tally table, the pictograph and the bar graph all show five, three and six.

Here, each mark, each picture and each square stands for one child.
