The 'Maths Worksheets' were covered earlier, but are still useful to revisit. Then please try the 'Alternative Maths Worksheets' too.
You could also follow this link to the 'BBC Bitesize' site. Then scroll down to the 'I want to learn' section, click on the 'Maths' box and scroll down to the lessons dated 18th May to 22nd May to use this week if you would like further resources.
