SWBAT to understand bivariate data by constructing and interpreting scatter plots.

Big Idea

Introduce the idea of bivariate data with real-life connections.

Warm Up

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

Today’s Warm Up is a bit different, in that it was the first day back from a break.  In that case, we reviewed the break packet.


Play of the Day

During this time, I work with my students as a group to consolidate the day’s learning by choosing 1-2 problems to review.   I NEVER skip this part of the lesson – it’s critical to really “bake in” the learning the kids just experienced.

A few thoughts here:

  1. I generally do one problem that is very straightforward, to increase their confidence that they learned what we set out to learn in our objective. 
  2. I then choose 1-2 problems that required more sophisticated thinking, and often let kids present their own reasoning, and then open it up to others to critique their reasoning.  This is a key part of the Common Core Mathematical Practice Standards (MP3).

Tonight's assignment (HW118 Introduction to bivariate data) is to be completed at home and should take students approximately 15 minutes.
