BUT DON'T SKIP THEM! Unless my high school kids are just woefully underprepared, kids to not enter high school (and in many cases they don't leave high school) able to make and read a graph. They can enter data and let Excel or Google Sheets make a graph, but they don't 'get' graphs yet. They need to spend time -- and for younger/less prepared kids a lot of time -- figuring out that slope and intercept of a best fit line (and area under it) matter. They need to process that way deeper than they want to, and without a bunch of time and effort spent on actions like this they simply won't. They need a bunch of this sort of experiment -- most of it with 'well-behaved' data, before they can really get good at interpreting a graph. I don't spend enough time on this part of my year, and it comes back to bite me later on, pretty much every year. Maybe I need to practice what I preach...Anonymoushttps://www.blogger.com/profile/09822196974112962100noreply@blogger.com
