Challenging Problems

I asked #MTBoS & Twitter in general for suggestions for resources with challenging problems (not lessons or activities, just problems), preferably searchable by CCSS or math concept/skill.  Many people asked me to share. Here is some of what I heard along with some I already use:

Open Middle

Don Steward's Blog

Art of Problem Solving


U of Waterloo

Math Forum POWs

NCTM Figure This

Maths Challenge

You Cubed - Tasks

The Mathematical Tool Box (book)

Feel free to leave other suggestions in the comments section. Thanks!
