# Q3, W7: February 14-18 Pre-Algebra

Teacher Kristin Andreason Pre-Algebra 8 February 14-18 Focus 8: Functions
Standard(s) Taught

MAFS.8.F.1.2: Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).  For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.

MAFS.8.EE.2.5: Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.

MAFS.8.EE.2.6: Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane.

Learning Targets and Learning Criteria
• identify the properties of a function written in algebraic form (e.g., rate of change, meaning of y-intercept and x-intercept, linear, non-linear).
• compare the properties of two functions that are represented differently (e.g., as an equation, in a table, graphically, or a verbal representation).
• determine the initial value/ y-intercept from a table, graph, equation, or two points
• explain slope as a constant rate of change (change in y over change in x)
Classroom Activities

Tuesday:

1. Students will take a Summative on Slope-Intercept Form of equations
2. Students will take notes on Linear vs. Non-linear Functions
3. We will do IXL’s BB.3 and BB.6 together

Wednesday:

1. We will explore interpreting the graph of a function
2. Students will do IXL BB.12 and BB.7
