Graph linear functions while solving for "y" first
Lesson 2 of 20
Objective: SWBAT define and graph linear functions.
Each day, students complete a Warmup that usually consists of spiraling the previous day's material, in addition to older material. Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.
For a video narrative about how I structure each lesson, and how the warm-up fits in, click Warm UP.
In this case, the warm-up gives the chance for kids to practice graphing from the previous day, in this case with a fractional coefficient for the slope. Ensuring this skill is solid is essential to success in today's lesson.
A few areas that I zero in on as a go over this problem and check for understanding:
- do students understand that the y-intercept is easily found on the coordinate grid?
- do students check that if the slope is positive, the line is sloping upward?
- can students handle fractional coefficients?
Play of the Day
The homework file is a resource that generally includes 5-7 problems that consist of problems related to this lesson, as well as spiraled review. I also give the kids the answers to the problems.
