Hi IamaSecretTwigletNibbler:
In years past (DD1 in Y6 - so we're still awaiting post SATs celebrations) - the school has a lot of activities which are less pressured but celebrate these last weeks together as good friends:
class play for Y6 July Assembly (lots of writing/ making of sets)
Y6 Leaver's service (Y6 write most of the church service)
Y6 fundraising scheme (each year makes something for fundraising for the school - calendar's, dish clothes, cook books, etc...) - They have to research idea, prepare business plan (all costings for materials, time to make it, etc...) and compete in teams to be the winning design for Y6 fundraising project. Then Y6 heavily involved in making product/ promoting their product/ selling product. (City also has a school wide competition regarding Y6 enterprise competition).
Sports Day (Y6 referee, organise events & run refreshment stand)
School Talent Show (Y6 decide who is included, organise event).
Summer Fayre - Y6 traditionally come up with stall ideas and help run many of the stalls/ set up / clean up. Y6 tally up expenses/ earnings on day & work out profit. Y6 also allowed to chose to spend 10% of profits on a gift to the school - for example purchase of tree/ shrub or bench or sports equipment all children can play with/ enjoy.
'Tiny Teachers' - Y6 pupils do more with KS1 pupils - especially supporting reading/ phonics. They get some training each week from Head of English before working with partners.
Y6 Trip - usually to amusement park like Alton Towers. They love it. Teachers not so sure about roller coasters.
City-wide Y6 CofE Leaver's service (takes 1/2 day).
Y6 competitions - class is divided into groups and each are given puzzles (brain teaser type things with riddles to solve) as a group. First to solve it wins points. Several competitions (often maths/ fact related) - overall winning team gets choice of Y6 field trip destination. Seems to always be Alton Towers - so everybody is happy.
Usually one or two - isn't it a nice day - let's go to the nearby park and play cricket/ football/ have races mornings/ afternoon.
My general view is this is both an opportunity to blow off steam, have some last good times together before heading off to various different senior schools & there does seem to be a lot of writing/ planning/ maths going on - but in very practical ways.
DD1 is doing nothing but review, review, review for SATs just now (I think school is seriously concerned about numbers able to achieve NCL4) but knowing all this amazing stuff is coming keeps her cheerfully working away.
