Sliding Puzzle for Cellular Respiration and Photosynthesis

This is one print. Students are challenged to slide the pieces to make the formula for cellular respiration or photosynthesis going from left to right. The teacher decides if it should be on the top row, or middle row or bottoms row. It's a race for each student to finish first. I also included a blank so you can make your own words on them. Tell me what you think!
