The Shapes illustrated nonfiction books provide the first lessons on common shapes. Rhyming text and creative illustrations draw attention to where triangles are found in the world around us.
A great any age introduction to triangles. I love the find them in ordinary pictures. Any age group.
I've read several of the shape books by Lorbiecki and this was the best one. The triangle finding in each picture was a little more complicated (far and near) and helped kids recognize triangles but still have a challenge. Great shape book. preschool and up.
