Firstly I would be recommending using the publisher websites- whichever ones your child's books are from. Folens, EDCO, and CJ Fallon have all opened up their resources for parents, this way the songs, books and interactive materials are familiar to your child, and you can just revise everything they have done.
The websites linked below are just useful ones if you need anything extra.
Junior Classes Maths/English
Into the Book
Word Family Sort
Fun 4 the Brain
Learning Games for Kids
Sesame Street Games
