Share your secret sauce with other teachers!

Have you designed a great lesson plan for your class, developed an interesting worksheet or set of problems for your students, or created exciting labs and activities to supplement your science/math textbook? How would you like to share this creative product with your teaching community? We’d like to hear about it.
Just donate your favorite problem set, worksheet, lab, activity or lesson plan that covers any of the middle- or high-school science/math subjects and we will publish it on CK-12 under the CC-BY-NC-SA license. Attach your work to an email and include the abstract of your idea, the grade level for which it is intended and the course it is designed to cover. Send your work as a Word document to submissions@ck12.org .
Thanks for your interest in CK-12 Foundation and for sharing your secret sauce with the teaching community at large!
