On Saturday I presented a short topic at the Auckland Mathematics Association morning session on getting started with CODAP (Common Online Data Analysis Platform https://codap.concord.org/).
Notes and links from the session can be found at http://tinyurl.com/AMA-29June2019.
In addition there are three draft activities that I have been working on. All three are part of a bigger lesson sequence so they need to be viewed with that in mind.
The first one looks at introducing measures of centre using CODAP.
The second one looks at a progression for scatter graphs, around curriculum level 5, using Q-plots to see if there is an association or not.
The third one is a look at posing investigative questions.
