Author note — to cover

Translate shapes on axes by column vectors, top component across and bottom component up, negatives handled, and read off the vector between object and image — G24's translations as 2D vectors. Vector arithmetic beyond translation lives on the Vectors topic. Both tiers. (G7, G24)

• Fluency — direct questions on translation by a column vector, 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).
