Note that unlike most Treasure Hunts, this one has the added feature that the answers give an encrypted clue. Deciphering this clue reveals where the treasure is hidden!

A Treasure Hunt is a great activity which children love. They are ideal for revision, starters or plenaries. They are a really great way to get students to answer questions quickly and enjoy doing so.

These question cards have been prepared in two sizes. The large cards can be pinned around the classroom and used for a whole class activity; the smaller (loop cards) can be used for group work or by individuals – they are particularly helpful for one-to-one tutorials and during interventions.

Colour coding:
I have used colours to indicate the approximate level of the questions:
KS2 – red and orange
KS3/GCSE Foundation – orange and green
GCSE Higher – green, blue and purple
