Ever wondered what minuend and subtrahend actually mean?
They both come from Latin — and once you know their roots, they suddenly make perfect sense.
The minuend? The number that must be made smaller.
The subtrahend? The part that must be subtracted.
Little words, big clarity.

Instead of showing colleagues a scheme activity, Lewis Horsley starts with the curriculum objective.
From there, teachers collaborate on small steps, anchor tasks, hinge questions, scaffolds and challenges.
That’s real collaborative planning.
