  • Asteroids - Yr3, Otford, Kent
  •  
  • We work hard on this for our early work and found 18. We're very proud of ourselves for being so smart.
  • Mr Morriss, Montgmery High School
  •  
  • Love these types of starter as they are great for any ability. They get the students motivated if they can see that you value their answers, I collected the results on the whiteboard but had to write them all out which was a bit time consuming and would have taken longer had I got the students to do it. To make it more practical to do this, if it was made more interactive so either the teacher or student could use a whiteboard pen or click on the three numbers and it writes the numbers they picked at the side to the class can see them and if they repeat one it shows them by highlighting that its already been found. Would be a massive help with these type of starters. But the website is great please keep them coming, my classes and I love them.

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.

Laptops In Lessons

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=April10

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

Here is the URL which will take them to student version of this activity.
