Objective and success criteria
Students will: Sort things: which one does not belong?.
- 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: 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 · 5 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? cherry, cat, sheep, horse (cherry / cat / sheep / horse) → cherryPrompt: What do most of them have in common?
- Sort these into animals and fruit: pear, cat, cat, pear, pear. How many are animals? → 2Prompt: Go through the list one at a time.
- Which one does not belong? plum, cherry, apple, coat (plum / cherry / apple / coat) → coatPrompt: What do most of them have in common?
Hook · 5 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 · 10 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 · 10 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? pear, coat, sock, shirt (pear / coat / sock / shirt) → pearPrompt: What do most of them have in common?
- Sort these into animals and vehicles: cat, cat, boat, sheep, bike, duck, horse. How many are animals? → 5Prompt: Go through the list one at a time.
You do: independent practice · 10 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 · 5 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Which one does not belong? bike, boat, car, apple (bike / boat / car / apple) → applePrompt: What do most of them have in common?
- Sort these into fruit and clothes: sock, cherry, apple, banana. How many are fruit? → 3Prompt: Go through the list one at a time.
Watch out for
- Forgetting to put data in order before finding the median.
- Reading a bar's height wrongly when the scale goes up in 2s or 5s.
Support and stretch
Support
- Use concrete materials: squared paper for charts.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Move on to: Sort, count and compare groups.
- Explain a common mistake in writing and how to fix it.
