Extra help
Stuck on something? Just ask.
Every MathOs teacher is happy to meet one-on-one with any camper who needs extra help — whether that's a tricky topic from camp, homework from school, or a concept they've been wanting to understand for a while. We'll find time before or after a session and work through it together.
Want more material?
Reach out — we'll send more.
If your child is interested and wants to keep going between sessions, students or parents can email us and we'll share extra problem sets, project ideas, and reading recommendations matched to their current skill level.
