Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
Guided Notes →One page your students fill in and keep.
Exit Ticket →Three items at the end of class. No student accounts.
Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
Homework →Assign practice; it grades itself.

"Create and use a system of two linear equations in two variables to solve problems in a variety of contexts." "Identify or create a system of linear equations in two variables to model constraints or conditions on two quantities."

Write one equation per stated condition
Recognize the count-and-value pattern across varied contexts
Model comparison and rate situations as systems
Identify which system models a situation without solving it
Solve a modeled system and interpret both values in context
