Introduction to the number plane/coordinate points…

Maths lessons

(NB. I haven’t fiddled to work out what to do with this yet, but found this very thing on Desmos here:


Adapted from Dan Meyer’s session at the 2014 love learning conference, this lesson forms a good introduction to ‘Straight Line Graphs’ – in particular the opening to the year 8 curriculum material on understanding the number plane / Cartesian plane. (see below for additional desmos task)

  • Begin the lesson with asking students for names of different fruits – type them up in a list for future reference
  • Then ask the students to rank them (say 1-12 for a dozen fruits) – no more information given at this stage. May need to ‘google images’ some of the different fruits!
  • Discuss answers / extremes of most tasty/least tasty etc.
  • Next show them the image of the axes. Discuss meaning of ‘quadrant’ and label the 4 quadrants. Screen Shot 2015-08-12 at 2.36.25 pm
  • Ask them to now work with a partner to put their fruit into quadrants (can either just put in a quadrant generally or specifically in a part of the quadrant – work towards this discussing scale etc)
  • Fuel discussions along with debates/exploring meanings etc. Could also ask ‘if you were a fruit, which quadrant would be the best/worst to be in’ etc). Could also show someone else’s example to compare:

This task can be extended by asking them to create/share their own version of the task. Could possibly show them the example of the movie stars – see link for this and more (incl. most of above!) here

NB. Here’s a nice image I found later that ties together some concepts here, as well as a good chat about the value of maths!

NB> perhaps something to go with this/build on with computers is Nathan Kraft’s desmos activity.
