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.

Every year, thousands of children lose their hair to leukemia and other medical conditions. Fortunately, there are organizations that help them by turning donated hair into wigs. How long does it take to donate hair? Donating hair is a generous act, but it also takes a long time to grow an entire wig’s worth of hair.
Students write and solve linear equations to determine how long it would take to donate a wig’s worth of hair and discuss ways they can support peers with conditions like Leukemia and alopecia.
