In the fall of 2024, Citizen Math released updated versions of every lesson in our library, plus a few new ones! We know you may have already prepped an earlier version or planned a repeat of last year, so we're continuing to make these earlier versions available through Thursday December 5, 2024.
You can find the new lessons through the regular search, and we hope you love them as much as we do. You can read more about these updates in Our Community.
