My students have been studying 2-dimensional and 3-dimensional shapes.  One way we’ve worked on this concept is with our shape booklet.  Students took the booklet home and searched for items in their house that were certain 2-dimensional and 3-dimensional shapes.  Then, they brought their shape books back to school and we all shared pictures of the shapes we found.  It’s been a great way for them to see that a can of green beans is also a cylinder!  Grab a free copy of the booklet from Google Docs to use with your class if you’d like.
