  • Integration of Themes: Friends
  • Social Justice, Human Rights and a healthy environment: “I am in Grade 2 with many other children. Each learner needs to be happy. The educator needs a suitable learning environment in order to teach us.”
  • Discuss the learner’s responsibility to create such an environment.
  • Taking turns on the jungle gym is important – why? Discuss safety, manners, co-operation, etc.
  • Learners extend their number concept to 109 on the “jungle gym”. The activities include ordinals, names, symbols and counting forward and backward.
  • Position is established by places in the classroom, using a floor map of the room.
  • A graph is designed to be completed by collecting information.
  • Addition and subtraction are extended to +4, -4, +5, -5, +6, -6, +7, -7.
  • Bonds of 10 and 11 are discovered.
  • Directions are given to draw and colour a shape.
  • Measuring with thumbs and comparison of these measurements using the related vocabulary.
