I printed some figures on cardstock for the students to cut out. I like the bright colors because I think it makes the concepts stand out on the page. We traced the shapes then reflected, translated, and rotated them. We used tape on one side of the triangles to show a reflection and glued in other figures and labeled them all. This part was a review for the students and a reminder of the definition of each term.
We also did a page similar to the one in this blog I found on Teaching Blog Addict to compare line symmetry and rotational symmetry. Most middle school students are pretty proficient at line symmetry but rotational symmetry is a bit trickier because it requires a big dose of visual-spatial reasoning. Some students just have a hard time seeing the new orientation in their minds. It takes practice, and I think the interactive notebook page helps them with this concept.
