  • This is just the sort of quick activity we should squeeze into our lessons more often. It is a classic arithmetic task that leads to pupils thinking about place value and how it might help them with their mental calculating abilities. This activity won't take long and is ideal for taking advantage of the time just before the main part of the lesson starts. Did it work well for your class?

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=June8

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