I’ve been busy in the last few days making activity pages for my spring 2012 book, Seeing Symmetry. There is a very cool site called Teachers Pay Teachers that has about a zillion free and paid lesson plans, slide shows, and other classroom materials. Students can make a symmetrical Christmas holiday or
winter tree out of squares and rectangles with this printable activity. They measure and mark a line of symmetry on construction paper then
cut out, sort, and arrange the shapes. The snowflakes will help them
center each shape along the line of symmetry. It’s great for math centers and instructions are included. To download this FREE 3-page PDF, please click to visit my “store.”
Saddle up for a fun way to explore line symmetry…if you click on the low-res image above, it'll go to my web page where you can download the high-res PDF. The idea is that students color the boots identically as mirror images. So, if the heel is brown on one boot, the heel is brown on the other boot. Simple counting questions reinforce the symmetry concept that if one boot has 3 big stars, the other boot must have 3 big stars also.
This activity page is adapted from my upcoming spring 2012 picture book, Seeing Symmetry. Enjoy!
