Complete 4-page Year 10 Foundation lesson on mode, median, and range from frequency tables — including the cumulative frequency method for the median.

Inside the pack

• Retrieval Do Now with separate Retrieval section — four single-step items per box, all primed for today’s three operations
• Three rule boxes: mode, range, and median (with CF column built step by step)
• I Do → We Do for each measure — six worked examples across realistic Year 10 contexts
• Spot the Mistake — three errors all rooted in the same trap: reading the frequency column instead of the data column
• Independent Practice — two full tables (library books; doctor visits), find all three measures for each
• Going Deeper: construct a table satisfying given constraints (mode = 4, range = 5), then reason about possible medians
• Exit Ticket + metacognitive reflection
