Hawken MS Math

Thinking of areas as a way to compute products leads to some lovely division possibilities in later algebra courses. Jim Tanton's "Galley Method" makes this particularly elegant.

This is a lovely fractions problem. I suspect most would try to find common denominators as that is what they've been trained to do. In this case, common numerators are easy to find and make the solution easier.

This is a really cool approach to student learning & self-assessment. Jill uses a calculus example to make her point, but it could easily be applied to almost any other math (or other discipline's) content. It is a pretty radical departure from where we currently are, though.

A lovely 3D visualization problem

A potentially fun PEMDAS BINGO game. NOTE 1: The provided problems all use 3-5 integers, basic 4 operations, & parentheses. NOTE 2: Very few parentheses and no exponents, roots, or absolute values are used. NOTE 3: This can easily be strengthened with other expressions, if needed.

A phenomenal site for ideas for students, your kids, or just some cool creativity and connections.

Another cool approach to this problem is to reflect either the hole or the ball over one of the sides and see if there is a direct line shot. Stripping down problems from all the textbook chatter is a grand way to get students thinking. And students defining their own problems is brilliant!

A great "conversation" between Patrick Honner & Grant Wiggins on the nature of rigor.
