This is a whole lesson on Histograms (lesson two). This is building on lesson one and specifically looking at working backwards to find the frequency and how to find a total sample size when given a key.
This lesson is designed for higher ability A/A* students at GCSE, but is equally apt for S1 and AS Level students. It comes with a starter, key questions, worksheets that I like to use as well as the answers embedded, superb teaching slides and examples and plenary.
