Math links: clocks

My kids have eagerly been looking forward to learning to tell time.  I told them they had to first learn to count by 5’s, and they’ve mostly mastered that, now we’re moving on to the telling time.

And of course, if you’re going to learn how, you need a clock!

Supplies: 2 different colors of fun foam, two circles of different sizes to trace, a brad, a marker

1.  From your two different colors of fun foam trace the two circles.  And let your kids have at the cutting out of the circles.  While they’re doing that trace two arrows for the clock.  Don’t forget to make one shorter than the other.

Oh, and am I the only one who has wondered why the hour which is longer is much shorter than the minute hand?  I did kind of figure it out when we were working on our clocks, I have a theory.  But, it’s something I’ve always wondered.

2.  Glue the smaller circle on top of the bigger circle, and then punch a hole in it with your nice pointy scissors or a knife.  Do the same for the arrows because your hole punch was broken by some overly excited hole punching by your child…….

Then on the small circle write your hours, this is to have yet another reminder that the hour hand is shorter.  Seriously I struggled with this for years.  And on the larger circle write the minutes by 5’s.  My kids thought this was super cool (I will add I wrote all of the numbers to not aggravate them and make this fun).
As you can tell, the clocks are wildly popular, and we’ve used them everyday since we made them.
