This activity gives students practice at working out LCM or HCF of two numbers.
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.
Unlike most treasure hunts, this one has the added feature that the answers to the questions give an encrypted clue. When students decipher this clue, it reveals where the treasure is hidden!
The question cards have been prepared in two sizes. The large version can be pinned around the room and used for a whole class activity.
The smaller cards can be used for group work or by individuals. The smaller cards are particularly helpful during interventions.
Colour coding
I have used colours to indicate the increasing difficulty of questions:
- Red, Orange and Green (from primary up to GCSE Foundation)
- Blue and Purple (GCSE Higher)
