Bill Day teaches middle-school math in Washington, D.C. He received the 2013-14 Teacher of the Year award for the district.
Hear about a math concept he believes eighth graders should master to be successful in high school.
“In my eighth grade classroom, I really focus my students on understanding the concept of a function. In particular, focusing on linear functions where one quantity is related to another with some initial value and then a constant rate of change. For example, if a gym charges a registration fee of $50 and then $20 per month. If I gave that scenario to my students, I’d want them to be able to build a function that relates that registration fee as an initial value and then the monthly fee as a rate of change.”
Real-life problems look and sound like word problems. Can your eighth grader use linear equations to work them out like this?
