Curriculum for Wales Alignment

Area of Learning and Experience (AoLE)

Mathematics and Numeracy

Relevant Curriculum Objectives / Statements of What Matters

• SM3: Mathematics and numeracy help us interpret and understand the world.
• SM4: Reasoning and analysing by applying mathematical skills are essential to solving problems.

Progression Steps (Year 5 Focused)

• Number and Measure:
  • Use familiar metric units and convert between units, including time.
  • Read, write, and convert between analogue and digital 12-hour and 24-hour times.
  • Solve problems involving calculation and conversion of time intervals.

Key Competencies Developed

• Using symbols and rules of maths fluently
• Applying mathematical skills to everyday problems
• Reasoning and justifying conclusions

---

Learning Intentions

By the end of this lesson, students will:

• Understand the concepts of hours and minutes.
• Read time on both analogue and digital clocks correctly.
• Convert between different time formats (12-hour analogue and digital).
• Begin to express time calculation in everyday contexts.

---

Success Criteria

Students will be able to:

• Accurately read time to the nearest five minutes on an analogue clock.
• Correctly tell the time on digital clocks in 12-hour format.
• Represent given times using both analogue and digital formats.

---

Resources Needed

• Large classroom analogue clock with movable hands (tea timer style or demo clock)
• Individual analogue clocks/manipulatives for student pairs
• Digital clock cards/display devices
• Printed time conversion worksheets (differentiated)
• Whiteboard and markers
• Visual aids/posters illustrating time concepts (hours/minutes)
• Stopwatch or timer for quick activities

---

Lesson Structure

1. Starter: Time Talk (5 Minutes)

• Begin by showing different analogue and digital clocks on the board—some showing the same time, some different.
• Ask: "What do you notice about these clocks? How are they the same or different?"
• Recap the definitions of hours and minutes. Use a visual poster to reinforce.
• Activate prior knowledge by a quick group shout: "How many hours in a day? How many minutes in an hour?"

Differentiation: Visual cues displayed prominently. Key vocabulary on screen (hours, minutes, analogue, digital).

---

2. Main Activity Part 1: Reading Analogue Clocks (15 Minutes)

• Demonstrate how to read an analogue clock using the classroom demo clock.
• Explain the hour hand vs minute hand, emphasising the minute hand moves in increments of 5 minutes.
• In pairs, students use their own analogue clock manipulatives to set times dictated by the teacher (e.g. 3:15, 7:45).
• Rotate around the room to prompt and correct misconceptions.
• Challenge: Students explain to their partner how they know the time.

Differentiation: Provide number cards for hour and minute marks. Offer sentence starters for explaining time ("The hour hand is on..., the minute hand is on...").

---

3. Main Activity Part 2: Digital and Conversion (10 Minutes)

• Display digital times on the board (12-hour format e.g. 04:30 pm).
• Show how to match these times with their analogue equivalent.
• Students complete a worksheet matching digital to analogue times and vice versa.
• Include some questions where students write digital time from an analogue drawing and vice versa.

Differentiation:

• Support group: Simplified worksheet with hour times only (e.g., 1:00, 2:00).
• Advanced learners: Include 24-hour clock conversion questions and discuss ambiguity of am/pm.

---

4. Plenary: Quickfire Time Conversion Challenge (10 Minutes)

• Use a timer and call out different times. Students quickly show time on their analogue clock or write the digital equivalent.
• Include "odd" times (e.g., 12:55, 11:05) to check deeper understanding.
• Discuss any tricky times as a group.

Extension Activity for Advanced Learners:

• Introduce concept of time zones with simple examples (e.g., "If it is 3:00 pm here, what time is it in New York?").
• Encourage these learners to explain how time differences affect scheduling across the world.

Differentiation Strategies

Learner Type	Strategy
Visual learners	Use colourful clocks, clear posters, and image-rich explanations.
Kinesthetic learners	Provide hands-on clock manipulatives for active participation.
EAL / Language Support	Use simplified sentences, vocabulary flashcards, peer support, and modelling.
SEN / Additional Needs	Offer 1:1 support where possible, use tactile clocks, and repeated guided practice.
Advanced learners	Challenge with 24-hour clock, time zone exploration, and extended problem-solving tasks.

---

Assessment for Learning (AfL)

• Observe students during hands-on activities, noting those who confidently read and set times.
• Quick verbal questioning during plenary to assess recall and application.
• Review worksheets for accuracy and understanding.
• Peer discussion to assess verbal explanation skills of the clock reading.

---

Reflection & Next Steps

• Note students who struggled with minute hand increments or conversion. Plan targeted mini-interventions in lesson 2.
• Incorporate more digital-analogue time comparison activities.
• Next lesson focus: Calculating elapsed time and solving time interval problems.

---

Additional Teacher Notes

• Emphasise use of everyday examples—trains, TV programmes, school timetable—to contextualise learning.
• Use clear mathematical language linked to CfW’s emphasis on communication and reasoning.
• Celebrate students’ success with quick “time teller” badges or praise tags to encourage engagement.

This lesson plan is designed to fully engage Year 5 students in mastering the fundamentals of time measurement, firmly rooted in Curriculum for Wales requirements, while providing flexible support and enrichment opportunities for diverse learners.
