The biggest lesson I have learned is that my students need to practice. 3 or 4 problems is not enough. They might whine somewhat about the worksheet, but they are hopeless without a lot of practice. The thing to do is not to have other activities replace practice, but to have a lot of practice incorporated into more authentic activities (e.g. labs).
Practice, practice, practice.
And slow down.
and don’t assume anything, especially if you didn’t teach them last term.
