Representing numbers with objects (age 8+)
Draw a scaled picture graph and a scaled bar graph to represent a data set; solve one- and two-step comparison, sum, and difference problems using bar charts, pictograms, and tables
Typical age: 8–9 years
“If your child looked at a bar chart showing how many books different children read last month, could they work out the total, find the difference between the most and least, and draw their own chart with a scale like "each square = 2 books"?”
