Number Corner

Each morning we practice math skills through a routine that is called Number Corner.  The themes of Number Corner change monthly.  One part of last month's Number Corner was to collect time, specifically 60 minutes a day for 24 days, to represent the 24 hours in a day.  (See the vertical chart to the left of the clocks.) Before we started collecting, we estimated how many minutes are in a day.  As the month progressed we revised and eliminated some estimates.  When we had collected 60 minutes on the 12th hour, a student explained how we could use that estimate to figure out how many minutes we would have on the 24th hour.  (See the pink writing on the white board.)  Just recently we had collected 960 minutes and we had to add 60 more minutes.  What a challenge!  We have popsicle sticks bundled in groups of 10 to help us count 60 more.  One of the children showed us on the white board what she did to figure out this problem.  (See the picture below.)
