Year 1 Maths at home

[Bobobab]

Would anyone recommend Maths Factor or similar? I'm finding it hard to help with the basics if that makes sense and my ds has definitely lost some of the knowledge he seemed to have in Reception

Mathsfactor is good for teaching the basics. There is a video for each lesson that explains the concepts and some fun games for extra practice. They often have a free trial if you want to see whether it is suitable.
