Objective and success criteria
Students will: Sort things: which one does not belong?.

Before and after
Needs first: no earlier skill in the map; start from what students know.
Leads to: Sort, count and compare groups
Materials: Squared paper for charts, Class survey data, Sticky notes for a live chart, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 6 min
- Quick retrieval: three short questions students should already manage. Answers on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Which one does not belong? car, bike, shirt, boat (car / bike / shirt / boat) → shirtPrompt: What do most of them have in common?
- Sort these into fruit and clothes: banana, sock, hat, cherry. How many are fruit? → 2Prompt: Go through the list one at a time.
- Which one does not belong? sheep, dog, bus, duck (sheep / dog / bus / duck) → busPrompt: What do most of them have in common?
Hook · 6 min
- Take a quick class survey (favorite fruit, travel to school) and ask what the results tell us.
- Share the objective: Sort things: which one does not belong?. 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: Which one does not belong? car, apple, boat, train
- Step 1: The others are vehicles; apple is not.
- Step 2: apple
- Answer: apple
- 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.
- Which one does not belong? shirt, banana, scarf, sock (shirt / banana / scarf / sock) → bananaPrompt: What do most of them have in common?
- Sort these into animals and clothes: horse, scarf, horse, dog, horse. How many are animals? → 4Prompt: Go through the list one at a time.
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.
- Which one does not belong? banana, cherry, coat, apple (banana / cherry / coat / apple) → coatPrompt: What do most of them have in common?
- Sort these into animals and clothes: hat, horse, coat, dog. How many are animals? → 2Prompt: Go through the list one at a time.
