Marie is in charge of a camp site. She makes a tally chart to record the number of campers booked in to the camp site during a bank holiday weekend. Identify one mistake with the tally chart. Marie creates a pictogram to show the information for Sunday and Monday. Identify one mistake with the pictogram.

Each mark on the tally chart represents one person. If we consider Sunday, each of the four parts circled represents five people. Five multiplied by four is equal to 20. There’re three more tallies. Therefore, the total for Sunday should be 23. We can, therefore, say that one mistake with the tally chart is that the tally for Sunday represents 23 instead of 24.

The second part of our question asked us to look at the pictogram. We’re told that the tent shape, which has three triangles, represents four campers. This means that the last shape in Monday is one-third of this as it has one triangle and not three.

The three tents circled represent 12 campers as four multiplied by three is equal to 12. The last part of the pictogram should represent one person as 12 plus one equals 13. However, one-third of four is not equal to one. In fact, it is not possible as it doesn’t give us a whole number answer.

We can, therefore, say that the pictogram for Monday does not represent 13 campers as one-third of four is not possible. This is one mistake with the pictogram.
