Day 1 · Teacher planDay 1 of 5
Lines of symmetry
Children practise “Lines of symmetry” with talk, the board picture, and a short worksheet. About 40 minutes.
We are learning to
- explain lines of symmetry in Year 4 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 “Lines of symmetry”,
- 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 “Lines of symmetry”. 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?” |
On the board
Leave “Lines of symmetry” on screen for the main block.

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 lines of symmetry.
