January Update for 8th-Grade Math

8th graders take an interesting angle on linear functions

January brings us to the main focus of the eighth grade linear functions. Students extend what they already know about unit rates and proportional relationships to linear equations and their graphs. We will  understand the connections between proportional relationships, lines, and linear equations in this unit.  The students will  learn to apply the skills they acquired in Grades 6 and 7, with respect to symbolic notation and properties of equality to transcribe and solve equations in one variable and then in two variables. These are the foundation skills for understanding functions and systems of equations.

 

MATH REGENTS: Students are reviewing what they know about linear functions to explore non linear graphs and their meanings. They will gain a deeper understanding of domain and range. They will also use scatter plots to display data and along with their knowledge of linear functions, create best fit trend lines or lines of regression.
