  • Looks good, could engage students in finding mode. But what's a Smile test? Percentage of what?

    [Transum: The Smile Test was a made up term for the purposes of this starter.]
  • Hagelsteens, Netherlands

  • And what is now the answer ?
    There is no median?
    Usefull in lesson.

    [Transum: As there are an even number of faces the median will be the value mid way between the middle two faces.]

  • Love this, great interactive board activity.
  • Maria Darroch, Rolleston College

  • I really liked this starter, but there was nowhere to have their answers checked and because the numbers change when you click on it, I couldn't prepare in advance. But it gave us good discussion around the median.
  • Bob Harlin, USA
  •  
  • Great Starter exercise for engaging students.
  • Mrs Prolina, TeRonga School
  •  
  • I think this is an excellent learning platform for my students... they loved doing this activity and all the other maths starters for the week. Keep up the great work.

Note to teacher: Doing this activity once with a class helps students develop strategies. It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated.

Teacher, do your students have access to computers such as tablets, iPads or Laptops?  This page was really designed for projection on a whiteboard but if you really want the students to have access to it here is a concise URL for a version of this page without the comments:

Transum.org/go/?Start=June16

However it would be better to assign one of the student interactive activities below.

Here is the URL which will take them to a self marking quiz about averages.
