    1. Hi Adam,
      We missed you at the Class meeting today on WebEx. Have you been getting my emails?
      On OneNote go to the Content Library and click on Daily Timetable, then Friday 24/4.
      Scroll down to the Maths lesson (it has a picture of a cubby house).
      The ‘plan’ you need to put in is you plan for either the marble run or the diorama (as in the application section).
      Let me know if this doesn’t make sense.
      Libby
