I'm a tutor based in the South East of England and this channel features various videos I have made, usually for my pupils and their parents, to help with maths problems they have struggled with.
A particular feature is Singapore Maths style Bar Modelling. Most of the Bar Model questions are suitable for upper KS2 and above. While there are a lot of bar model drawing tools available I deliberately choose not to use them for my videos (despite my terrible drawing skills!) because I want to replicate what I would do with pencil and paper so that YOU can see how to do it for yourself.
