These websites have been helpful to me, especially when supply teaching.
Resource websites
ICT Games A variety of games covering different subjects can be found here.
Twinkl (My go to site for supply teaching when there are no resources or anything left at all!)
Oxford Owl A range of books that can be read online.
GPic There are so many great fiction and non-fiction books for the interactive whiteboard.
Science Sparks
BBC Bitesize
Pobble
TES There are a lot of resources if you use the search. You need to register to download. Some are free and some are paid.
Topmarks
White Rose Maths
Talk for Writing
Phonics Play The children enjoy some of these games. I paid to join this stie.
STEM
Primary Resources A variety of resources covering all the primary age range as well as EAL and some SEN resources.
I especially like the Email Genie on this AI site.
The above is another brilliant one.
