I haven't taught it in 4 years, and figured this would be a good time to pool some resources. One thing I really want to concentrate on this year is number sense and mental math. I decided last night-- at about 2 am when I was wide awake thinking about this stuff- that my Do Now for the forseeable future is going to be times tables. Yep, my Honors classes in my College Prep school are going to do times tables for at least the first few weeks of school. Then we'll move on to perfect squares and perfect cubes. Some of them have been using calculators for so long they've forgotten how to think. I've been trolling the internet for some worksheets and projects, and will be happy to share what I've found so far with anyone who wants it.
