📈 Scaled Picture and Bar Graphs

What you’ll learn

1. One Picture, Many ThingsRead a scaled pictogram where each symbol represents several items.When numbers get big, one symbol can stand for a group — like each star meaning 5 books. Count in that step size to read totals, and remember a half symbol shows half of the group. Scaled pictograms let us show large amounts with just a few pictures.
2. Scaled Bar GraphsRead a scaled bar graph whose axis counts up in steps.A scaled bar graph has a side scale that counts in steps, such as 5s. A bar's value is how many steps it reaches multiplied by the step size. Scaling keeps big numbers inside a small, neat graph so they are easy to draw and read.
3. Solving Graph PuzzlesSolve one- and two-step problems using scaled graphs.To solve graph puzzles, first read each value using the scale, then do the maths. One-step questions compare or add two values; two-step questions might add two bars and then compare with a third. Taking it one step at a time turns big graphs into simple sums.
