Grade 8 - Graph and analyze two-variable linear relationships
According to the BC Ministry of Education Prescribed Learning Outcomes for Math 8 in the area of Patterns and Relations:
It is expected that students will:
B1 graph and analyse two-variable linear relations
In order for students to successfully learn how to graph and analyse two-variable linear relations, it is important to scaffold the following activities:
solve a given problem involving integers taking into consideration the order of operations
determine the missing value in an ordered pair for a given equation
create a table of values by substituting values for a variable in the equation of a given linear relation
construct a graph from the equation of a given linear relation (limited to discrete data)
describe the relationship between the variables of a given graph
Once students have these skills, they will be able to successfully graph and analyze two-variable linear relationships.
Students draw upon both geometry and algebra skills when learning how to graph and analyze two-variable linear relations and will have varying degrees of expertise in grasping these concepts. For this reason, it is beneficial for students to have access to tutorial resources that can help them address gaps in their learning and provide additional learning resources in both areas of geometry and algebra. GeoGebra is an excellent platform to use for this purpose because it focusses on both algebra and geometry skills. To illustrate the effectiveness of using GeoGebra as a digital learning tool in your classroom, please go to the following lesson exemplars - Order of Operations, Isolating a variable, Ordered Pairs of a given equation, Creating a table of values, Constructing a graph and Describing the relationship between variables of a given graph.
