We learned this as “yours is not to question why, just invert and multiply” so I did this procedure without knowing what I was doing.

Halve 12 to 6 and double 25 to 50; 6x50 is 300

@jbrickwedde.bsky.social Nicely done!

Excellent video! Thanks for helping me make sense of MP2 @sarahmoffett.bsky.social

Some had experience and for some it was their first time. We didn’t teach them anything upfront. Just get into it, find out what you can, choose a tool and model the subtraction problem.

I would love to hear more about your ideas for this!

We put the prompt in a shared google doc with a link to Polypad. Nothing formal so don’t have anything to share.

We do that too. I hear from HS teachers they can tell who skipped a grade because they end up with gaps in their understanding. So hard to shift a system entrenched in this practice.

MN Math Leaders solving 72-46 using PolyPad and sharing strategies during awesome PLC session. Check out how the same tool was used to model in very different ways. So cool! #MNmath #MCTM #polypad #iteachmath

What are your thoughts on a 3 in 2 course in middle school so they don’t skip an entire grade level of content and are subject accelerated by 8th grade?

Excited to read the blog Marilyn!
