Objective and success criteria
Students will: Match time words to digital times.
- 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: Tell the time to the half hour
Leads to: the next skill in this area.
Materials: Rulers, scales and measuring jugs, Clock faces, Conversion chart, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 4 min
- Quick retrieval from earlier learning (Tell the time to the half hour). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
Hook · 3 min
- Ask the class to estimate the length of the room or the weight of a bag before measuring it.
- Share the objective: Match time words to digital times. Read the success criteria together.
I do: model it · 7 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: Write "half past 8" as a digital time, like 4:30.
- Step 1: 8:30
- Answer: 8:30
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 6 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- Write "half past 6" as a digital time, like 4:30. → 6:30Prompt: Half past means 30 minutes after the hour.
- Which words match 11:30? (11 o'clock / 6 o'clock / half past 11 / half past 12) → half past 11Prompt: Look at the minutes first: :00 or :30?
You do: independent practice · 7 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 6 questions are on the student sheet below, with answers in the key.
Exit ticket · 3 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Which words match 4:30? (half past 4 / 6 o'clock / 4 o'clock / half past 5) → half past 4Prompt: Look at the minutes first: :00 or :30?
- Write "3 o'clock" as a digital time, like 4:30. → 3:00Prompt: O'clock means 00 minutes.
Watch out for
- Measuring from the end of the ruler instead of zero.
- Converting units the wrong way (multiplying instead of dividing).
Support and stretch
Support
- Review first: Tell the time to the half hour.
- Use concrete materials: rulers, scales and measuring jugs.
- 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.
