Author note — to cover

GCSE vectors are 2D column vectors only — no 3D and no i-j component notation, both A level. Cover the column as a displacement, top entry across and bottom entry up with signs, bold-letter and arrow-over-AB notation, and the contrast with the position a coordinate pair names. Both tiers. (G25)

• Fluency — direct questions on column vectors, 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).
