How to Teach Slope
Students encountered linear relationships with positive rates of change and either positive or negative vertical intercepts. The graphs of these relationships all had an uphill appearance. After reflecting on commonalities and differences between lines that slope in different directions, students explore a situation in which one quantity decreases at a constant rate in relation to a second quantity. They interpret a graph of the situation and reason that it makes sense for the slope to be negative in terms of the context. The scenario is then extended to consider a quantity that does not change with respect to another, and students realize that a flat graph has a slope of zero. Lesson 9 Slopes Don't Have to be Positive. Lesson Narrative.
Slope From A Table Worksheet
English Language Arts. Students learn how to represent, interpret, and analyze functions in various forms, leading to understanding features such as rates of change, initial values, and intervals of increase and decrease. In Unit 4, eighth-grade students are introduced to the concept of a function that relates inputs and outputs. They begin by investigating all types of relationships between sets, such as students and their number of siblings, coins and the number of minutes of parking at a meter, distance and time spent running, etc. They learn how to represent and interpret functions in various forms, including tables, equations, graphs, and verbal descriptions MP. As students progress through the unit, they analyze functions to better understand features such as rates of change, initial values, and intervals of increase or decrease, which in turn enables students to make comparisons across functions even when they are not represented in the same format. Students analyze real-world situations for rates of change and initial values and use these features to construct equations to model the function relationships MP.
Comparing Functions 8th Grade
After about 4 minutes, I will ask three students to deeply discuss their responses to the Do-Now aloud. I will ask students to share out what they already know about the rate of change, and to recall where we have used it before. Each group will also have white boards and markers to write on in lieu of guided notes. Most of my students are familiar with slope formula from their middle school math classes, so today's lesson aims to further their understanding of this concept, and to show students the connection to the linear functions we have been studying in class.
