In my classroom we do a rocks unit every year - which covers all the items of the common core. To spice up my rocks unit, each student is able to have their own self picked pet rock. The variety of rocks gives us plenty of things to talk about as a class and compare. Each student gets to do various activities with their pet rock - including my Pet Rock Class Book. Each page in the class book lets students tell where their pet rock came from, what is looks like, what it "eats" and "likes to do" and a fun fact about their pet rock. The book comes with a full cover or black line cover. The book has two formats - one with mainly pictures for younger students and one with writing for older students.
