Functions Vs. Relations
Oh my goodness.... I have such a hard time teaching functions and relations until I came across thei website. Purple math does a great job of explaining how to teach functions and relations. It also goes in depth about the "Vertical line" test and how to use that test to determine the outcome of the test. This is an awesome resource to use to teach this skill.
This resource addresses the learning expectation by providing excellent content material to teach relations and functions.
