This Counting Atoms Looping Activity will help your students master counting atoms in chemical formulas using subscripts and coefficients. This activity has students up and moving around your classroom and checking their work as they go. Students will begin all around the room with the different chemical formulas. They must answer their question on their answer sheet and then look for that answer around the room written in bold under another question. That will be the next question they will answer. The bold answers allow students to check their work as they go. This is a great activity after students have learned the basics of counting atoms in chemical formulas.
