Our current unit of learning in maths requires my young people to work with time. Our pre-assessment showed that many of them have somehow missed a lot of the skills involved in reading analogue clocks so I've paused our official unit to redress this.
I started with a review of my understanding of the sequential development of reading time. Recognising that the reading of digital time is significantly easier, I started with a recap on the parts of an analogue clock face and their roles. I went right back to basics and we made interactive clock faces inspired by this pin.
My research highlighted that at this age confusion about the hour and minute hands is often still prevalent, and this has been the case for many of my young people. Another point of confusion in our class is about hand movement. We've worked hard to remove this confusion and today we had quite a few a-ha moments. You know the ones:
"So it takes an hour for the big hand to go all the way around, but the little hand only moves between two numbers in one hour?"Yes indeed!
Next I pulled out the big guns: a packet of Tic Tocs! (For readers outside of Australia: Tic Tocs are a round iced vanilla biscuit (cookie), with clock faces embossed on the underside, made by Arnotts.)
|Our white boards.|
The clocks were essentially cast aside by some children as understanding developed. Other children continued to use their clocks to self-check. The high flyers worked in 24hour time, challenging themselves to make word problems to match my elapsed times. (Yes, I did scribble them down for future use!)
|You may be able to see here that each number on the clock|
has a flap. Underneath has :05 or :35 etc.
This relates to the following Australian Professional Standards for Teachers...

Standard 2 Know the content and how to teach it
Standard 3 Plan for and implement effective teaching and learning
Standard 5 Assess, provide feedback and report on student learning
