*Being Resilient is part of our Developing Mathematical Habits of Mind collection.*

In Developing Students' Resilience, we offer you support and advice on how to encourage your students to become resilient mathematicians.

We know that good thinkers are resilient, they don't give up easily, and are motivated to work hard and keep going when faced with challenges. Here are some problems that may require similar determination from your students. You could warn your students that the solutions may not be immediately obvious, and they may need to persevere. We hope that they will have the opportunity to appreciate that
success can be sweeter after a struggle.*You can browse through the Number, Algebra, Geometry or Statistics collections, or scroll down to see the full set of problems below.*
