Year group and teacher's initials here, so DS1 is in 5PD and DS2 is in 3KD. The two YR classes are RIK (R for Reception, IK for teacher's initials) and RCC.
Been like that for the 8 years I have had DC going through the school.
They have houses for house points and sports day and competitions though, Oak Ash, Fir and Chestnut. They are placed in a house at the end of YR. Each house wears different colour tops on sports day etc, Oak is yellow, Ash is dark blue (to distinguish from the light blue of the normal uniform tops), Fir is green, and Chestnut is red.
They always place siblings and step/half siblings in the same house, even if they have different addresses, the rest of the pupils get put in houses where there are spaces left, to ensure an even split through the school.
My DC are in Chestnut. Chestnut won sports day yesterday even though both my DS's came last in their races. They get the trophy this year, so it now has red ribbons tied to the handles in the display case.
Yay for our school still having a proper competitive sports day. My DC KNOW that they will come last, but they still have to do a race, and accept that they will come last, but they might be better at maths or science or art or history than the winners of every race.
They did stop the parents race 4 years ago after a mum broke her ankle - now that DID get ultra competitive!
