Summary
Student will graph a picture. Find the domain of the line segments of the picture are drawn. Then graph line segments with fixed domain. Then students color in the picture and rewrite the linear functions as inequalities that match the shading. They use technology to check their line segments and inequalities.

Language:
domain and range
one variable inequality
linear function

Differentiation

All students

# 1 – 5

Review of prior learning but in new context.

Domain and range

graph lines

#6 – 7

Write equations of inequalities.

Most students

# 8

Create their own picture.

Grouping: Individual
Formative Assessment:
#5 & 7

Students self assess

Systems of Equations Learning Targets

Practice 6. Attend to precision.


AREIc I can represent and solve equations and inequalities graphically.

AREI.12 Graph the solutions to a linear inequality in two variables as a halfplane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding halfplanes.


BIG Idea:Students will be able to graph data, find a function that best fits data, find and interpret correlation coefficient, graph residual plots to determine if the function is the best model, and use the model to make predictions.
