A note home
This week in maths we work on conditional probability: narrowing the world with \'given\'. Ask: What did you practise today?

The whole class, then the narrowed group
Children practise “The whole class, then the narrowed group” with talk, the board picture, and a short worksheet. About 40 minutes.
We are learning to
- explain the whole class, then the narrowed group in Year 10 words,
- use the board picture to check thinking,
- record an example on paper.
Success criteria
- I can show one example of today’s idea.
- I can say the idea in a short sentence.
You need
- interactive unit open on “The whole class, then the narrowed group”,
- worksheet (next sheet), one per child,
Lesson flow (about 40 minutes)
| 5 min | Warm-up Ask: “What might help us today?” |
| 10 min | On the board Open “The whole class, then the narrowed group”. Ask: “What changed on the screen?” |
| 15 min | Worksheet Children complete the day sheet. |
| 10 min | Share Ask: “In one sentence, what was today’s idea?” |
Watch for
- Skipping the board -- bring them back to the picture.
- Correct answer with no explanation -- ask how do you know?
Answers and look-fors
- Meeting the idea sounds like a clear sentence about the whole class, then the narrowed group.
