These are some pages from my 7th grade interactive notebook.
On the left page the students completed tessellations using translations and rotations. (See information about this resource below.)
I bought one of these Getting Smarter Every Day books years ago when I was at a math training. It has some great problem solving activities in it, and I've even used some of the pages as ideas for bulletin boards. I copied the pages above from Book E Grades 6-8 for my students to use on these interactive notebook pages. I also used pages from this book for their polygons notebook pages.
