  • I like this.. maybe give a few more numbers and get them to practise. Then try doubling.
  • 7abM2, King Alfred's College, Oxfordshire UK
  •  
  • We found this a challenging puzzle. But in the 5mins we managed to write 27 numbers. Can you beat this?
  • Class 9Ma1, Sheredes School
  •  
  • We discussed this and Stefan noticed that all the numbers ended in 5. We had a discussion and then further noticed that the numbers ended in 125 and 625 in rotation. The class wondered why this should be the case.
  • St Bernadette's, Twitter
  •  
  • 7th Grade St Gregs,
  •  
  • The class went on for a good amount of time. I feel even the 5th grade class could do it!
    Transum is highly approved and something to look forward to in my class.

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=March9

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

Here is the URL which will provide a little light relief. It is a game based on the sequence of doubling numbers but might be best left till the last five minutes of the lesson as it is quite addictive!
