What should we add? How about making dots of different colors, and providing notes about how many of each, plus the running total? Easy-peasy. We just need to do the arithmetic to work out where to put everything.

The [[Activities/TurtleArt/Tutorials/Triangular_Numbers_Program|program to generate the triangular numbers]] takes up a lot of space, so I am putting it on another page.

A problem that TA can't solve for us directly is the formula for triangular numbers. Gauss figured it out on his own as a child, but the rest of us need a hint, at least. Here is a big hint.
