I See Reasoning - Live Lessons - UKS2


What is a 'live lesson'?

  • Every weekday at 9am, Gareth Metcalfe posts 2 new lessons to his page via YouTube.
  • One aimed at children in UKS2 and another for LKS2.
  • Each video will help children to build the skills needed for the main task.
  • Children will then complete the main task – a challenge or short series of questions – working individually or with adult/sibling support.
  • Underneath each video is a short description of the key calculation skills for each lesson.
  • Tasks (with answers included) can be downloaded from underneath the videos below.



  • If you have not tried these videos before, you might like to begin right from the very first one, on Mon 23rd March. 
  • Some of them lead on from each other or come as a pair, for example they may say 'Part 1' and 'Part 2' or a particular concept, so be careful if you are picking and choosing which to do.


Please note, we will aim to upload the most up to date video to this page, each day after the live broadcast. To make sure you catch the lessons as they go live at 9am, the website link is:

There is an incorrect video for Year 5 and 6 on the 'I See Reasoning' website for today's date, however there is a task that is for this age group (see document under video). As an alternative, I have included the Year 3 and 4 video as it shows a similar concept, but at a lower level. Hopefully the video should help with understanding the task.
