Although learning to tell time is not a math skill, and is not included as a Common Core Standard in kindergarten, the teaching of clocks as a tool for mathematical thinking is crucial.
A clock is made of the numbers 1-12 laid out in numerical order. This alone makes the clock a handy aid when teaching counting and cardinality. Giving a student opportunity to work with clocks help develop number recognition, sequencing, and numerical order.
I think I have introduced clocks the first day back from winter break for the entire 23 years of my career (thank you Ruth Hepworth). Waiting for Monday morning, right at my carpet/calendar area, I have my little student size Judy Clocks ready to go and my copy of Hap Palmer’s, Paper Clocksready for the play button to be pushed. After we have manipulated the clocks to the song a couple of times, I love to have the students construct their own clocks to take home and show off their new skill of telling time to the hour.
