• Integration of Themes: Friends
• Social Justice: Friends should spend time together, e.g. playing games. Discuss in small groups what your attitude towards your friends should be when you play together.
• A healthy environment: Why is sport important? Discuss the safety precautions needed when participating in sport at school.
• Inclusively: Who should be allowed to participate in sport at school? Only team players? Or should the school accommodate everyone? Make you own graph of which learners participate in sport.

• Number concept is extended to 50.
• Counting in 2’s, 3’s, 4’s, 5’s and 10’s.
• Calendar activities enable learners to order the months and revise ordinals.
• Graph – a weather graph can be completed.
• Bonds of 10 are introduced with many opportunities to reinforce these.
• Measurement activities involving comparisons of height, length, width using related vocabulary.
• Capacity – litre;
• Identifying coins and shapes are included.
