# Hair Today, Gone Tomorrow

## How long does it take to donate to Locks of Love?

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.

### REAL WORLD TAKEAWAYS

• It takes ~100 inches of hair for Locks of Love to make a single wig. It would take an individual more than 16-20 years to donate a complete wig. If a classroom full of students worked together, they could donate a full wig in a fraction of the time!
• Groups of people can often make an impact more quickly by working together.

### MATH OBJECTIVES

• Write and solve one-variable equations to solve real-world problems

Appropriate most times as students are developing conceptual understanding.
