Recognising powers of 2, 3, 4 and 5, which N6 names explicitly; squares to 15 squared and cubes of 1 to 5 and 10; writing 64 as a power of 2, 4 or 8. Estimating roots of non-powers lives on Measures estimating-roots. Both tiers. (N6)

• Fluency — direct questions on recognising powers of a number, 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).
