I am so excited to repost this blog. Christopher Danielson, who writes Talking Math with Your Kids, has created a super shape book that is accessible for all ages. What's great about the book is that there are no right or wrong answers. This book is all about explaining and justifying your thinking. I can't wait to share this resource with my kindergarten teachers who are just about to begin their geometry units! When I first read the post I was sitting next to my own kindergartener (the one who I take home every night) and I thought, "Hey, I'll try this out on her." We scrolled through each page and had a great conversation around why we chose each shape. It was interesting, when I disagreed with her, choosing a different shape for a different reason, she was pretty willing to go along with my idea. I asked her, "Who's right?" and she quickly said, "You must be, I guess!" It took a few pages of convincing her that we could both be right and by the end it was a bit of a game to see just how different our thinking could be. I especially appreciate the developmentally specific prompts given in the post so families and teachers can use the book with varying age groups. I've included some additional supplemental pages on my Downloads page if you want to add to the book. When I printed the PDF the pages came out, with a border, to be a 7 3/4 square so I tried to size my supplemental pages to fit the originals. Please take the time to read more posts from Talking Math with Your Kids. So many goodies!
