Our school has run an Easter school this year. The children not invited were very, very put out. Those not initially invited but with fussy parents were then allowed to go anyway. Those not in year 6 wanted to know why they couldn't have Easter school, as did some of the parents. I might offer to run an Easter or Christmas school for KS1 next year. A few days of cookery or art or music or maths or sport or writing or whatever might be fun!
