I have been spending time talking with kindergarteners, first and second graders in schools about my shapes book (coming from Stenhouse, Spring 2016). Many more school visits are ahead of me. I have written up some reflections for a more teacher-ish audience than this blog attracts. If you’re interested in the ways young children talk about shapes, and in what I hear in their ideas, hop on over to the sister-blog Overthinking My Teaching for the details.

You may be delighted to learn how much math there is in the simple collection of shapes below.

I am working on the simple shapes with my 2 1/2 year old Grandson in preschool right now. Thanks for the post.

I used them in a junior kindergarten class (four year olds) who had not had much experience with “formal” geometry. It was fascinating to listen to their sorting rules and rationales. I was interested to see how many looked at orientation before colour or size. What a wonderful age, and what a wonderful book you have given us. (I am using it this week with math teachers, let’s see what they say!)

Thanks for posting this! I teach Adult Basic Education. Some of the writing sections on the new GED ask students to answer a prompt using evidence from a text. We posted a page from your book. Students were asked to pick a shape and write about what evidence they noticed that suggested it did not belong. It went well! Thank you.

What a great idea for a writing assignment, Abby!

This is such a fascinating topic, Christopher. I love your blog–math is endlessly interesting and so are kids’ brains!

Interesting blog.

Hi Christopher,

This is really great, thanks! I showed this book to my 6 year old and she was surprised that all of these objects constituted “shapes.” We also had a great time with the “odd one out” discussions. I learned a lot about her mathematical thinking from them. As for having a rich discussion about simple shapes, here is one I had with a group of kids just about rectangles https://aofradkin.wordpress.com/2014/09/30/what-is-a-rectangle/

amazing games..thanks for sharing this..kids can also get some latest cool ideas of shape games from this awesome game here: http://goo.gl/ywg6Vl
