cation + learning's teaching materials and assessments are thoughtful, concise and focused. All materials were written for (and are currently used) in my high school chemistry classroom. Many concepts, however, are cross-curricular and may be useful in other science classes and grade levels.

Please do not share or re-sell, distribute, or alter for mass production. If you need to purchase multiple copies, please utilize discounted rate provided.

Spot a typo? Want to change something specific (units, font, etc.)? E-mail me and let me know! I’ll send you (and possibly all purchasers) an updated version ASAP.

Thank you for viewing (and hopefully purchasing!) cation + learning’s teaching materials and assessments!
