I'm still working on the subtraction puzzle you set 😕and now I'm thinking I should add a level 8 with negative numbers!!!

There seems to be lots of ways to extend this activity to provide many investigation opportunities. Wonderful

Wow that’s very creative 🫡

Very nice - like it

Thanks Colleen!

There are so many of them. You could start with this list:

Really great to hear that Colleen. I still have some laminated versions from way back (though they weren’t called drag and drop then 😆)
