Happy Numbers

A simple investigation focusing on the mental arithmetic skills of addition and squaring numbers as well as thinking logically. It is hoped that students will not go through all numbers sequentially but will soon realise that all numbers in a HAPPY chain are happy and all numbers in a SAD chain are sad. Thereby including/eliminating numbers very quickly.
Worksheet if needed at slide 6 and the all-important answer sheet at slide 7.
