The home learning pack contains both English and maths work (these booklets have already been included in the physical resources being given to children).
White Rose maths learning
This is the scheme we use in school normally and it features helpful videos, activities and answers to help teach and practise maths skills.
Oxford Owls activity suggestions and links
This website links to more than just maths and suggests ideas for keeping boredom at bay such as writing reviews for past purchases on Amazon or following a simple recipe.
Maths frame website
Full of interactive games and activities, but the difficulty and coverage is more random, so some games may be too easy or too challenging, but definitely worth a look.
