Data Handling

Sorting things and reading simple pictographs and tally marks — with an interactive exercise.

We sort things and show how many with a pictograph (a picture chart).

In a simple pictograph, each picture stands for 1 item. To compare groups, count each one. A tally uses marks to count: |||| means 4.

Remember

  • Each picture in a simple pictograph = 1 item.
  • Count each group to compare.
