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=June18 However it would be better to assign one of the student interactive activities below. 

Here is the URL which will take them to a related student activity.
The answer to the extension activity is 190 + 54 + 113 + 170 = 527
