MATH FUN: February 11

The theme for todays activity is the Olympics !  A few children remember seeing some skiing on tv and Sofia knew that I was an" Olympic really really fast runner."  She wondered if I retired because "it's too hard to run in the snow. " I reassured her that I retired simply because I could not run anymore and that this was a very long time ago.  But just how long?  We calculated this in 3 different ways 1) longhand subtraction 2) count by decades i.e. 1992 to 2002 is 10 years, 2002-2012 is 10 years & 2012 to 2014 is 2 years. 10 + 10 + 2= 22 years.

But how long is 22 years?

3)  I asked each child how old they were.  Francine and Mila said that they were 4.5 years old; Roy and Sofia said they are 4 years old.  Each child was given 4 red beans, in 4 groups and then we counted, 16 beans + 1 bean (Mila & Francine's half year combined) = 17 beans.  We repeated this task for the number 22 and discovered that we needed 5 groups of 4 with 2 beans left over.  The children could see the difference in the length of the chains.


The children making 4 groups of 4 beans to represent the sum of their ages in years compared to the number of years ago I competed in the Olympics.




Our next task was to have some fun with the Olympic rings and colour the intersections and then make their own Olympic rings !

    1. He kept going back and forth between math and the magna tile area- it's cool that he thought about things and asked questions at home !
