##### Regrouping

I’ve been reading Peter Mattock’s book Visible Maths. I’m only two chapters in but I’m really enjoying it. Visual representations is something I haven’t really learnt much about. I’ve dabbled in bar modelling, but I’m a stranger to things like Cuisenaire rods. So much so that I had to read up on how to spell them.

I particularly like this

I often do regrouping and addition as one lesson and maybe I need to be more explicit introducing regrouping as a skill in itself.

So I came up with this, using mathsbot.com to generate the images. It didn’t take very long.
