Carnival of Mathematics #6

Carnival of MathematicsThe new Carnival of Mathematics is up and running at Modulo Errors. Highlights for me included:

Teaching Math
One opinion about when to introduce formal arithmetic (workbooky math) to children. What is the opportunity cost of too-early mathematics?

Criss-Cross Multiplication
An algorithm for two-digit multiplication that is easier for mental math.

Party For Polyglots
A brain teaser puzzle, not too difficult.

Coloring Knots
A topological doodling project.

Apparently, the link to my post on solving story problems got lost in editing the carnival. Here is where to find the article:

The Case of the Mysterious Story Problem
