This is a selection of free interactive teaching resources for the teaching of KS3 Computing and GCSE Computer Science. They can also be used for self-supported study. For further resources and schemes of work look in the Teachers section of the site and also in the Programming.
There are also some videos on the Computing and ICT in a Nutshell YouTube channel to accompany these pages, e.g. those on number bases and how to use Boolean Logic in your programming.
