This FREE product is all you need to have a very engaging gallery walk for your students as you introduce your rocks and minerals unit. Includes teacher directions, rules for the gallery walk, handouts for students to use during the walk, printable vocabulary words, and definitions. The images for the walk are perfect for having students work together to collaborate as they try to figure out what each set of pictures represents. This is my favorite activity for introducing a unit, and your students will love it as well! Great for use in interactive notebooks as well.
