    Thinking this is a strong example of why we have to build conceptual understanding before introducing the formula and algorithms. This is troubling because right now, we are in the middle of COVID-19 pandemic and schools are being pushed to focus on “priority” standards.This may leave measurement out of the picture, when we can see that it is such an important part of developing proportional reasoning. It’s ALL interconnected as the web shows.

    Bottom line – students have to know why the formula is the formula! That is the element of trust that gets built over time. But a lot of this is missing in the current way many U.S. teachers are teaching (at least in my experience).
