Pictograms and tally charts
Interpret and construct simple pictograms, tally charts, block diagrams, and simple tables
What a learner can do afterwards
- Read a pictogram where each symbol represents one item
- Construct a tally chart from collected data
- Draw a block diagram to represent data from a survey
The lesson
You already know how to read a pictogram, where each little picture stands for one item. Now let's learn two more ways to show data: tally charts and block diagrams.
Mia asked her class which fruit they liked best. She drew a tally mark for every answer, then counted the tallies and drew a block for each fruit. The tallest block shows apple was the favourite.
When you make a tally chart, count in fives. Draw four lines standing up, then draw the fifth line across them. A crossed group of five is easy to spot and count fast.
A tally chart counts with grouped marks, and a block diagram turns those counts into blocks you can compare at a glance.
