1.1. You are who you say you are. Your email address is legit, meaning it’s a real email address and one that you check. You will use a name that does not attempt to impersonate anyone else, and one that is not inappropriate.
1.2. Your Citizen Math Account is just for you, and should not be shared. You will not share your login credentials with others, nor will you give anyone permission to use materials that you accessed while you had an active license. As former teachers, we at Citizen Math know that sharing resources is an important part of collaboration, and we have provided some guidance in the next section on how to share appropriately.
2. Using Citizen Math.
2.1. You should use Citizen Math lessons and materials for only as long as you have an active license that gives you access to those lessons. This means that if your paid subscription expires, you should delete any materials previously downloaded from Citizen Math that are not available on the free plan. If you delete your account entirely, you should delete all Citizen Math materials.
2.1.1.Free trial licenses and paid license are both active licenses. An expired license on www.CitizenMath.com is not an active license.
2.1.2.When content is available for free on Citizen Math, you may use that without an active license but with an active account.
2.2. You may use Citizen Math in your classroom for non-commercial purposes. You may not use, distribute, resell, sublicense, or assign your right to access or use Citizen Math content to any third party or as part of any commercial product or service without our explicit written permission. Any attempt to do so will be null and void and shall be considered a material breach of the Terms.
2.3. You may not attempt to reverse engineer any component of the Citizen Math website, including the content and concepts therein.
3. Sharing Citizen Math. As a group of former teachers, the folks at Citizen Math understand that collaboration is an important part of professional development. Below is some guidance on what is and is not acceptable sharing related to Citizen Math lessons:
3.1. Please do blog about what happened in your classroom when you taught a Citizen Math lesson! This isn’t just allowed, it’s encouraged! Tell it from the mountains, you all. We’ve got a mission to share.
3.2. Please do reference Citizen Math lessons and discuss your own experiences with them as the leader of professional development, as long as you are operating as a classroom teacher, school or district curriculum specialist or other non-commercial agent. If you are “selling” your professional development, then pay attention to the paid consultant guidelines below.
3.3. Please do link to Citizen Math lesson pages on your website or blog. When you do this, give us a heads up by emailing email@example.com.
3.4. You should not post or share PDFs of downloadable materials – like student handouts, lesson guides, or old presentations -- from Citizen Math, EXCEPT YOU MAY share paper or digital copies of the Student Handout with students during the time you have an Active License for that lesson.

3.6. Generally, do not make or attempt to make Citizen Math content accessible off of www.citizenmath.com without explicit written permission from us to do so.

Paid consultants, curriculum writers and publishers, freelance professional development providers are not eligible for the monthly pay-what-you-can subscription.
4.2. Maximum Monthly Rate Terms: If you are not eligible for the pay-what-you-can option, you may still elect to sign up for a monthly account with recurring payments; however, you must pay the maximum monthly rate that is available at the time of your registration.

5.3. Group Managers may reassign licenses. When a Group Manager reassigns a license, the original license holder is removed from the group. Reassignment should be used to replace a user who should not be on the group license now or in the future. Reassignment should not be used to rotate or cycle through teachers. For example, you should not purchase and reassign a license to one teacher for short-term use with the intention of reassigning it back to the original user.
5.4. Unused licenses are not refundable and do not roll over to the following licensing period. If you purchase more licenses than are assigned or activated during your license period, you do not have a right to redeem those licenses in the future.

For example, you may not accept payment to do a workshop about Citizen Math lessons without our permission to do so. That said, we’re usually jazzed to hear that people are teaching Citizen Math lessons, so go ahead and ask!
