Skills Based Activity
This skill builder contains three lessons. The lessons have been designed to assist in teaching scatter plots to students with the aid of the Excel application, which is available free to all New Zealand Schools. The student lessons are supplied in Doc format to allow easy modification if you do not have access to computers.
As the activity is intended to be taught over at least three lessons, teachers should carefully read through each activity, the support notes and the presentation notes prior to teaching.
