Which One Doesn’t Belong

If for some reason, you haven’t looked at @trianglemancsd ‘s Which One Doesn’t Belong shapes book, check it out here.  It is a great gateway into math talk, vocabulary, critical thinking- all those things we cherish in our classroom.  Of course, my mind is always thinking of how I will take this gem back to my classroom and use it.  This book can truly be used by any grade level, conversations can be that rich- although the time that is needed for each one should decrease.  My first reaction was, “Why aren’t there also 3D shapes?”  I asked Christopher if he had any plans on incorporating these and he didn’t at the moment.  Kids live in an environment where 3D is the norm, and I think these same discussions (as well as new ones) can happen with the “more complicated” shapes.

Of course, now I will be working to assemble pages of these types of problems together!  Thanks @triannglemancsd!
