“A Tale of Two Division Contexts”

After my last blog post — talking with a Grade 3 class about division involving zero — my father reached out to me with another way to think about it. It reminded me of some work I did last fall.

I love this lesson! 😍

I have some students starting machine learning / data science projects this quarter. Introducing them to this framework.

Three pieces that tend to always get skipped:

I missed this post when it came through, but it still seems very relevant today => The Power of Connecting Instructional Routines by Jenna Laib jennalaib.wordpress.com/2017/09/20/mor…

After our 2nd and 3rd grade learning labs today in Miami Beach, one teacher said her biggest takeaway was that “You don’t need to work with big numbers to do big thinking.” I absolutely love this quote.
