I thought this website might be useful as it has loads of activities on for kids of various ages. It is from an American homeschooler so some of the spelling is different and she talks about grades/kindergarten.
Some of the topics (she calls them packets) are free some have a small fee. I have used some as a teacher and some as a parent and they good quality. There are some science experiments to do at home, Egg activities for Easter and topics range from Greek goddess to layers of the atmosphere.
