Sigma Tutor Challenge

Our next Tutor Challenge will be - Name the Tree

Sigma would like to name the Trees outside the Technology area as part of our Environment role.

Tutors groups can submit names as a whole, in teams or individuals.

They can choose any name but will need to give a short reason as to why they have chosen it. They could use famous environmentalists, an anagram of Tree - Ester, which is an American baby name meaning Star. 

There will be a prize for the winning tutor groups/teams/individuals and winning names will be put on a plaque and attached to the tree.

Please submit your Tree names to Mrs Arnold.

Prefect Interviews

It is an exciting time for Sigma Year 10 students from10RMO and 10MAH. They have been submitting their applications to become the next Sigma House Prefects. Interviews will take place on Friday 27 April. The newly appointed Sigma Prefects will be announced in the House Assembly on Thursday 3 May. Good luck to all the candidates.
