- Balancing- The children use scales to balance the gems.
- Counting- The children find the gems of their designated colour and count.
- Sorting- The children sort the gems into different pots based on their colour.
- Reading- The children find gems and bring them to the teacher. Each colour relates to a set of word cards within a treasure chest. As they bring the gems they must read a card from that chest. If they read it correctly they keep the gem. This game can also be played using just sounds.
