Development of Lesson:

      Introduction:

        For a fun and brief introduction to our lesson on scatter plots, each student will be handed a dot-to-dot activity. After completion, they will be told to try to look at their picture in a different way — told that this pattern of seemingly random dots could actually be an arrangement of data material.
      Methods/Procedures:
      1. As a class, we will watch the video about how to construct a scatter plot with a given set of data.
      2. Each student will then work on their own to complete a worksheet similar to what we saw in the movie. This will include interpreting a set of data, creating a scatter plot, and then identifying any correlation with the data if it exists.
      Accommodations/Adaptations:

        No real accommodations necessary. If any special needs students require assistance, I will be going around the room to help.
      Assessment/Evaluation:

        Students will turn in their completed scatter plots at the end of the allotted time for grading.
    Closure:

      This lesson is a precursor to the following lesson… no closure is necessary.
