Objective and success criteria
Students will: Spot shapes in the world around us.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: Name 2D shapes
Leads to: the next skill in this area.
Materials: Rulers and protractors, Squared or dotted paper, Shape cut-outs, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 6 min
- Quick retrieval from earlier learning (Name 2D shapes). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
Hook · 6 min
- Show a photo of a building, a tile pattern or a road sign and ask what shapes and angles students can spot.
- Share the objective: Spot shapes in the world around us. Read the success criteria together.
I do: model it · 12 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: What shape is a door?
- Step 1: Rectangle
- Answer: rectangle
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 12 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- What shape is a square cracker? (rectangle / triangle / hexagon / square) → squarePrompt: Picture it. Is it round, or does it have straight sides?
- What shape is a cell in a honeycomb? (rectangle / circle / hexagon / triangle) → hexagonPrompt: Picture it. Is it round, or does it have straight sides?
You do: independent practice · 17 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 7 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- What shape is a sandwich cut corner to corner (one piece)? (rectangle / square / triangle / hexagon) → trianglePrompt: Picture it. Is it round, or does it have straight sides?
- What shape is the cover of a book? (triangle / rectangle / square / circle) → rectanglePrompt: Picture it. Is it round, or does it have straight sides?
Watch out for
- Thinking a square turned on its corner is no longer a square.
- Reading the wrong scale on a protractor.
Support and stretch
Support
- Review first: Name 2D shapes.
- Use concrete materials: rulers and protractors.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
