### PRODUCT DESCRIPTION

This is a wonderful activity which uses a real life paradox to explore how ratios change by adding the same number to the quantities being compared. We start with our friend Bud and his nephew Lou. Bud is 40, Lou is 10, so the ratio of Bud's age to Lou's age is 40:10, or 4:1. 5 years later, Bud is 45, Lou is 15, so now the ratio has changed: their ratio is 45:15, which can be simplified down to 3:1.

Using this idea (which was based on a very inappropriate Abbot & Costello routine from long ago), we examine how the ratio of the two ages converge on 1:1 as Bud and Lou grow older and older. Includes detailed lesson plans, video link, cartoon question poster and answer key.

Includes writing ratios in simplest form and decimal form.
