How long does it take to donate to Locks of Love? Organizations like Locks of Love use donated hair to create wigs for children who need them. 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.
Write and solve one-variable equations to solve real-world problems
Before you begin
Students do not need prior experience writing and/or solving equations.
How much should you pay for a shared wireless plan? Students use proportional reasoning to predict whether a family will go over their minutes, messages, or megabytes, and decide how much each person should pay.
Expressions and Equations (EE), Number System (NS), Ratios and Proportional Relationships (RP)
Are coupons always a good deal? Students reason with percents and proportions to evaluate enticing coupons and debate whether retailers should be allowed to raise the price of items in order to then put them on sale.

Is it a good idea to rent a storage unit? Students write and solve multi-step equations to evaluate whether storage unit rentals are worth the cost and make recommendations for when people should store, sell, donate, or toss their unused stuff.

Like the jacket, this lesson is for Members only.
Mathalicious lessons provide teachers with an opportunity to teach standards-based math through real-world topics that students care about.
How have video game consoles changed over time? Students create exponential models to predict the speed of video game processors over time, compare their predictions to observed speeds, and consider the consequences as digital simulations become increasingly lifelike.
