Picture marks and bar heights encode data values; matching the named category to its mark and reading the scale lets us compare, calculate, and rebuild the data accurately.

What your child will figure out
- Read most and exact values from simple picture and bar graphs without relying on colour or position.
- Compare two bars and calculate the difference between their values.
- Build bars whose heights match supplied data values on a labelled scale.
- Transfer graph reading to scales greater than one and two-step total questions in adaptive practice.
The levels
- Picture power
Predict the most popular fruit, observe the picture counts, and explain that the row with the most marks represents the greatest value.
- Mind the gap
Compare two bar tops, calculate how many more votes one category has, and explain why the gap is the difference.
- Bar builder
Act on supplied raw data by dragging or tapping three bars to matching heights, then explain how the scale controls each height.
- Scaled transfer
Transfer graph reading to a scale counting in twos and combine two category values in a novel toy-lab context.
Ready when they are.
