Author note — to cover

Read roots where the curve crosses the x-axis and the y-intercept where it crosses the y-axis, from drawn graphs, including two-root, repeated-root and no-root cases. Graphical reading only — deducing roots algebraically by factorising belongs to the equations topic. Both tiers. (A11)

• Fluency — direct questions on roots and intercepts on a quadratic graph, limited to this lesson's stated scope (4 questions).
• Application — use the same skill in unfamiliar or contextual questions without introducing a later method (4 questions).
• Check — questions built around the exclusions and likely misconceptions named in the lesson brief (4 questions).
