Math enrichment problems at MathNotations

Today I want to highlight a blog called Math Notations by Dave Marain that specializes in math enrichment problems such as various type challenges and investigations. And they are quite good!

For example, recently Dave posted a geometry problem, and even gave the answer in his post, but he asked the readers to find DIFFERENT ways to solve the problem.

I encourage you to go see the problem and see how many different ways you can find to solve it!

That is exactly what we can ask students too - especially if you have many students and some of them solve the original problem in no time. You can use the same problem as a basis for further investigations for them.

His blog has "labels" in the sidebar, which makes it easy to find problems on a particular topic or concept.
