# Patterns and Functions: Fill 'er Up

### Source Institutions

PBS

In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container. Learners graph this as an ordered pair by using the number of the measure (x) and the resulting height of the water (y). Learners compare the ordered pairs of containers with various shapes, including irregular shapes.
