One of the videos that stood out to me in MML (mymathlab) this week was
the one with Cheyenne trying to figure out fair share for 18/6. At first
she was really, or at least seemed, unsure of what to do with the cubes she
had. Maybe I was just reading her wrong or didn't see what she was trying
to do at first? Anyway, she was asked if there were 18 cupcakes at the
birthday party and there were 6 kids how many cupcakes would each kid get if we
were to divide them equally among all the kids. She had 20 cubes in front
of her; she put two to the side and then proceeded to put 18 out in 3 rows
of 6. So she was able to figure out from that that each kid got 3 cupcakes.
I really like the idea of giving each child a bunch of cubes
in order to figure these types of problems out. You can just watch them
figuring it out right in front of you. Since I will be using this with my
son who is going into Kindergarten next fall this video was a great example for
me.
One of the problems I had this week was one about two
people having the same amount of something and then one giving one of theirs to
the other and then that meant that the one person had just one more than the
other. I knew they were asking why that was not accurate and I literally
couldn't figure it out in my mind! I was thinking, yeah that IS
right! So I did 4 slash marks for each and then took one away from one
and gave it to the other and it was obvious then that the person who gave away
one was now two short from the other person! Doing a little hands-on
always helps me and I am sure that is true of a lot of people.
My logic...
