Have a look online at White Rose Maths. You will find lots of ideas set out for practical maths activities at home. They work from a storybook starter but you don't have to have the book to be able to do the tasks.
I am posting the link to the Early Years section as I feel it is more appropriate for the children in The Pod but feel free to have a look around on the site.
The children also have maths set weekly on Purple Mash. These are called 2Dos.
The link for the login page is below:
You will find your child's login details in their reading diaries.
