One of the most difficult processes for chemistry students to learn is how to solve stoichiometry problems. This is a set of manipulatives to help students practice where to place the units and compounds while solving problems.
Each set contains several combinations of units and chemical compound, and a strip with a chemical reaction. I give the students a series of different problems and they move the cards to the right spots to make the conversion between grams, moles, or molecules.
The background template and cards are printed on cardstock with constrasting colors.
