I currently have 18 free products for teaching biology and chemistry to students in grades 7 - 12. These freebies are tried and true. I use them all the time in my classes, so they are guaranteed to be kid tested and user friendly.
These materials are ready to be copied and passed out to your students. Each product includes worksheets/handouts for the student, and guides for the teacher. Answer keys are always included.
