- First off, John Golden has created a great Carnival of Mathematics #108. (John, how can I get any work done if I play with all these posts?!)
- Maria Andersen announced the release of Algeboats.
- I think of the roller coaster projects as being about trig derivatives, but they might work well when I get around to the limits chapter, where we'll talk more about differentiability. (I do it after derivatives and before integrals.)
- Glenn is thinking about how to make some smooth connections from Algebra I thought Calc (and stat). I like what he's doing.
I really like Maria Droujkova's response to someone who asked about the Common Core. She (oh so diplomatically) mentioned what she likes. The mathematical practices:
1. Make sense of problems and persevere in solving them.Although I'm not sure their list is any better than Avery Pickford's Mathematical Habits of Mind. In other words, it's a good list, but not the only good one.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.
