SWBAT construct and interpret a line of best fit on a scatter plot.

Spiral students' understanding of bivariate data and linear functions by constructing a line of best fit.

10 minutes

Each day, students walk into my classroom, pick up a classwork packet (that has the warm-up as well as the classwork for the day in one easy to pick up packet), and work on 2-3 problems. At different parts of the year, this may look different. Most often, it takes two possibilities:

a) Reviewing the previous day’s work, which prepares kids to tackle today’s aim.

b) Spiraling previous content, particularly from major standards from the Common Core

The key is that one of the problems should have 1 problem that nearly every student can be successful at, and then 1-2 problems that push their thinking and illuminate something new. The first allows kids to feel immediate success at the lesson’s outset, and the second pushes kids to think more deeply about mathematics.

It is incredibly important that warm-ups do NOT take up more than 10 minutes. OK, maybe 11 minutes. But that’s it. Seriously… an opening routine that goes long is the Achilles heel of many lessons, and being smart about how much time to spend here is critical.

Here are today's Warm Up Problems: 9 - 2 WU119 Construct a line of best fit

15 minutes

9 - 2 HW119 Construct a line of best fit is to be completed at home and should take students approximately 15 minutes.
