# Summary of Lesson Plan:

The following is one tasty Mathematics lesson that focuses on converting 12- and 24-hour time. Students will explore what am and pm times are, what 24-hour time is and how we convert between them. For the following lesson you will need to purchase the Tic Toc biscuits to distribute to each student (There are 28 biscuits per packet and students will need a minimum of 6 biscuits each). This lesson aims to assist students understanding of converting into 24-hour time in a hands on, fun and engaging way.

### Mathematics:

• AC Mathematics: Year 4: ACMMG085 Convert between units of time.
• AC Mathematics: Year 4: ACMMG086 Use ‘am’ and ‘pm’ notation and solve simple time problems
• AC Mathematics: Year 5: ACMMG086 Compare 12- and 24-hour time systems and convert between them

# Lesson Plan Sequence:

Introduction – 10 Minutes

Focus: What do we know about time? What is the difference between them?

• What do we know about time? What is 12- and 24-hour time? Who would use these different times?
• PowerPoint slide 2 & 3: 12- and 24-hour time
• Video: 12 vs. 24-hour time: watch video

Body of Lesson – 45 Minutes

Focus: Converting 24- hour time

1. What’s the time slides (PowerPoint slides 5-8) discuss the times
2. IXL 24-hour time questions as a class IXL
3. Tic Toc Task: Explain Tic Toc Task to students (PowerPoint slide 9)
4. Hand out Tic Toc biscuits to students. Students complete time conversions using their given time on each biscuit
5. Extension activities:
6. Use two of your times from your Tic Toc biscuits to create an elapsed time problem. Record both of the times as an analogue clock and write the 24-hour time underneath. Show the elapsed time between the two times.
7. Tic Toc Timetable: Create a timetable for an event of your choice (zoo, show etc) Create times for each activity or presentation at your event. For example, zoo timetable: 13:30 petting zoo, 14:00 lion feeding, 14:50 large birds of prey presentation etc. Draw each time on an analogue clock.

Conclusion/Sharing/Reflection – 10 Minutes

• Students to share their Tic Toc times and eat the biscuits

• Create your own biscuit that demonstrates a mathematics concept (worksheet)
• Explore the sugars in Tic Toc and other kids’ biscuitsx`

# Assessment Ideas:

• Anecdotal notes on performance throughout the task.
• Take pictures as evidence for portfolios
