Transformations and Tessellations

I love teaching transformations.
These are some pages from my 7th grade interactive notebook.
Symmetry and Reflections Interactive Notebook Pages
The class took notes on lines of symmetry and reflecting figures over the x- and y-axes. On the left they completed an activity to reflect a design over both axes. (The source for this activity is below.)

Translations Interactive Notebook Page
For the translations lesson we did one example when a figure is drawn on the coordinate grid and one example for writing the coordinates of the image when only the original coordinates are given. Here is a resource you can use for printing coordinate grids in a variety of sizes.

Tessellation and Transformations Interactive Notebook Pages
To sum up the three types of transformations we studied, we outlined three figures on the page then reflected one using tape on one side, translated one, and rotated one. To the right we wrote the definition of each transformation. My 8th graders did a similar transformations page but had other notebook entries for translations and reflections. You can see some of their pages on my Transformations Notebook Pages blog.
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.

    I LOVE teaching middle school math! All the potential for learning and growth is inspiring. I have a master's degree in math education, and I've taught 6th - 8th grade math for more than a decade. I've also been a 5th grade teacher and an upper elementary math specialist working with small groups of students who struggled with math. I'm excited to write about what we're doing in class and hear your ideas too!
