Author note — to cover

Measure gradient as rise over run from a grid triangle and from two coordinates, with negative gradients for falling lines and fractional gradients included; steeper means larger magnitude. Out of scope: gradients of curves, which are Higher on gradients-and-areas, and writing equations, on the next pages. Both tiers. (A10)

• Fluency — direct questions on the gradient of a line, 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).
