Sometimes I wonder if anyone is reading these blog posts, but not anymore. The check marks referred to by Math Mom appeared shortly after (very shortly after) my post this morning. I am certain they weren’t there when I posted, and there are other changes to the names of the headings on the K-6 math page since this morning.

At the Math Night meeting, we were told that Investigations also includes teaching of algorithms. I guess they must mean the “multiple towers” approach which doesn’t really qualify in my book. Based on my fourth grader’s 2nd edition exposure last year and my careful review of the 5th grade workbook, Investigations still does NOT teach the US standard multiplication algorithm.

I just looked at the link to 2nd grade math pacing chart, and there was a small check mark by a couple of units- below the chart, the check mark is explained to mean that an algorithm will be introduced during that unit. But which algorithm would be introduced with a unit called, “Does it walk, crawl, or swim?” You got me. It sounds like a preschool unit- not a mathematical one for 2nd graders.
