Teaching Stoichiometry

I’ll say it – I used to hate moles! Stoichiometry was one of my least favourite topics in high school and I was quite annoyed to learn that it was something that I would be seeing a lot of in chemistry. When I became a teacher, I wasn’t very shocked to see despite the many years since I was in high school, the loathing of moles remained the same. So, I set out to create a set of resources for my students that would help them better understand moles and solve stoichiometry questions. I discovered there were really two keys to helping my students with this unit – giving them a blueprint to use to solve questions and giving them plenty of opportunities to practice and apply this blueprint to a variety of questions. With that in mind I've added a series of resources that are now available in my TPT store to help make your next stoichiometry unit a breeze!


Interactive Notebook

This is my guide to learning stoichiometry; I print off the entire notebook for students at the start of the unit and we work through it from start to finish. The notebook is designed to introduce the concept of moles and slowly build up to solving stoichiometry questions. Students learn how to balance equations, mole ratios, finding molar mass, how to do molar conversions, empirical and molecular formulas, percent composition by mass, limiting and excess reactants and percent yield. Each concept is fully explained, definitions provided, and a worked-out example provided for students to reference in the future.


Once I’ve taught a concept it’s time to reinforce, reinforce, reinforce. For me, the best way to learn how to solve stoichiometry problems are to practice stoichiometry problems. I created 21 sets of worksheets; each comes with two pages of questions for students to complete and a full answer key. These worksheets are also fully compatible with TPT Digital Activity, meaning you can assign them to students virtually [read more about TPT Digital Activity here].

Task Cards

Stoichiometry task cards can be used in a variety of ways to help students. Use them as an entrance or exit card to assess students’ prior knowledge or whether or not they grasp the concept once you’ve taught it. I also use them as a revision resource. Students can complete these cards individually or as group, and they are also compatible with TPT Digital Activity.

Test Questions

When it’s time for the unit test Stoichiometry Test Questions has over 150 questions you can choose from to customize the best test for your students’ needs. There are multiple choice questions, true or false, fill in the blanks, mole equations, calculation questions, short answer and long answer questions.
