Quick revision
Remember these!
- In a pictograph, one picture represents a set number of items.
- A key explains what each picture represents.
- A half symbol can represent half the full value.
- Pictographs make visual comparison easy.
- We estimate values by counting pictures.
- Pictographs can use different scales, like 1=5 or 1=10.
- Understanding scales makes reading pictographs flexible.
- This builds on earlier pictograph learning with more complexity.
