We began today with a good discussion about the place for calculators in the classroom. This is a very complex issue and relates to all sorts of other issues of “short cuts” versus “true understanding.” The general consensus seemed to be whether the tool is used as a crutch or for expediency once the process is fully understood.
I offered to continue our conversation so please feel free to email me at firstname.lastname@example.org. I’d be happy to help with lesson ideas and even implementation if it is on a Thursday!
We moved into some more investigation of the percentage problem by looking at the work of several students. And ended with our Bungie Barbie activity.
It was great working with all of you! Have a great summer.
I will include another blog with some information from Chase and more on the research on mathematical developmental stages.
