The rules for Kakooma are simple. Greg Tang developed this puzzle; I first heard him speak as a parent of elementary school children in 2002. Mr. Tang had a part in inspiring me to change my career to teach math. Subsequently, I attended one of his teach the teacher workshops.

## Conway Look and Say Sequence--Run Length Encoding

The **Conway Sequence** is a sequence of digits (also called **Look-and-Say sequence**) where each term is made of the reading of the digits (the number of consecutive digits) of the previous term. Conway created this sequence as a method of decoding called Run-Length Encoding.
