Dogball is an enigma. The bouncy toy exterior hides a rich yet accessible modelling task within; a delicious intersection of maths and science, a potential PSMT/Folio task for Stage 1 Mathematical Methods featuring low floor, high ceiling and room for unique student responses, and just a great bit of maths.

Dogball, and the modelling task he inspires, is introduced via a short video. The related data is included as a CSV file. Instructions on how to import CSV data into a Casio CG50 AU graphics calculator or into the Casio fx-CG Manager Plus.
