Reply To: Lesson 5-5: Extending Multiplicative Thinking – Discussion

[John Sasko]

My big takeaway was the need to build flexibility with multiplicative thinking. We need to do a better job of relating multiplication and division and including both statements that can be made when we, for example, compare the length of Wand A to Wand B.

I am also seeing the connections to measurement standards – some of which I fear are being dropped out during this COVID-19 pandemic and my district’s (NYC) focus on “priority standards.” Measurement standards are probably going to be given less focus, if any time this year and that is problemmatic! Length models — relational rods, number lines, connecting cubes are coming up so frequently and I really appreciate their role in building this understanding of multiplicative thinking. So much good stuff here!!

Thanks!
