Objective and success criteria
Students will: Tell time to five minutes.
- 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 time to the hour and half hour; Skip count by 2s, 5s, 10s and 100s
Leads to: Elapsed time; 12-hour and 24-hour clock; Say times to five minutes using past and to
Materials: Rulers, scales and measuring jugs, Clock faces, Conversion chart, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Tell time to the hour and half hour; Skip count by 2s, 5s, 10s and 100s). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Count by 10s. What is missing? 60, 70, 80, __, 100 → 90Prompt: How much does the count go up each time?
- Count by 5s. What is missing? 55, 60, 65, 70, __ → 75Prompt: How much does the count go up each time?
- Count by 2s. What is missing? 28, 30, __, 34, 36 → 32Prompt: How much does the count go up each time?
Hook · 5 min
- Ask the class to estimate the length of the room or the weight of a bag before measuring it.
- Share the objective: Tell time to five minutes. 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.
- Model one question from the student sheet, thinking aloud.
- 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.
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.
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 time to the hour and 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
- Move on to: Elapsed time; 12-hour and 24-hour clock; Say times to five minutes using past and to.
- 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.
