Corbett Maths is a great resource which you will be able to use during this period of enforced closure. It has lots of very useful videos which explain different areas of mathematics which you can watch with your children at home. I will also ask children to complete a daily '5-a-day' where they can practise five different aspects of mathematics each day. I will direct the children to watch certain videos when they relate to a topic, however please feel free to use them as and when you see fit.
