Experimenting with Functions: a week of ready-to-teach maths
Five days of lessons for Year 10 Algebra. Print this pack and the week is prepared.
Start here: five minutes to Monday
- Skim the week at a glance.
- Print the five days (plan + worksheet each).
- Cut out the card sheet once.
- Open the free interactive unit on your board.
- Teach from the plan.
The week at a glance
One lesson a day. Run them in order where you can.
| Day | Lesson | Children learn and do | On screen |
|---|---|---|---|
| 1 | Change one number, watch the line | Practise the idea with talk, board and worksheet | Board: Change one number, watch the line |
| 2 | Observe, conjecture, test | Practise the idea with talk, board and worksheet | Board: Observe, conjecture, test |
| 3 | Experimenting with a parabola | Practise the idea with talk, board and worksheet | Board: Experimenting with a parabola |
| 4 | Generalising a pattern into a rule | Practise the idea with talk, board and worksheet | Board: Generalising a pattern into a rule |
| 5 | One counterexample is enough | Practise the idea with talk, board and worksheet | Board: One counterexample is enough |
Materials
- This pack printed.
- Pencils and the board or projector.
- Optional counters or rulers if a day plan names them.
A note home
This week in maths we work on experimenting with functions. Ask: What did you practise today?

Change one number, watch the line
Children practise “Change one number, watch the line” with talk, the board picture, and a short worksheet. About 40 minutes.
We are learning to
- explain change one number, watch the line 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 “Change one number, watch the line”,
- 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 “Change one number, watch the line”. 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 change one number, watch the line.
