TODAY IN ALGEBRA 2.0… Warm Up Task: Exit to AT

Learning Goal 1: 2.3 You will graph linear equations in slope-intercept or standard form

Independent Practice

Learning Goal 2: COE – If I only had a car

Ch. 2 Quiz – Friday!

WARM UP: Complete the four problems on the quarter sheet on your table.

-We will correct them in class in 10 minutes.

-You must earn a 75% (3/4) on this warm up in order to be released during AT.

-If you earn less than 75%, you will stay in during AT to complete another quarter sheet of these problems.
