  • Inclusively: Although we are all unique, we share many similarities; appearance, sport, education etc.
  • Social Justice: Friends and their expected behaviour towards one another.
  • A healthy environment: This is our responsibility – what can we do about keeping our environment healthy?

Educator’s page

  • Each learner has page 7.
  • "Why do we want a calendar?" [ It tells us the days of the week, months of the year and the date. This is important so that we can know when our appointments are, when our birthdays are, which days are school days, which weekends, etc.]
  • What is the first day of the week? Sunday.
  • Let's say all the days of the week beginning from Sunday.
  • Questions: - Which day comes after e.g. Monday? After Friday, etc?- Which day comes before e.g. Wednesday? Before Sunday, etc?- Which day comes between Tuesday and Thursday, etc?- At which month of the year are we looking now?- How many days in January?- Count to 31 forward and backward.- On which day is the 3rd of January? How do you know? On which day is the 10th of January?- How many days from the second of January to the tenth?- What day is it today? Today is ......................... . Tomorrow will be ......................... . Yesterday was ......................... . - What is today's date?- When did school begin?- Count all the school days in January.- Which month comes after January?- Learn the song: January, February, March, April...- Read and do the instructions on page 7.
