8. participate as responsible citizens in the life of local, national, and global communities;

9. be culturally and aesthetically sensitive across a range of social contexts;

  • Integration of Themes:
  • Social justice: The story of the secret signs shows how history can be important. What are the advantages of knowing things about the past?

Learners can divide into groups, visit the library and do more research on the origin of our number system, the Roman numerals, etc.

Learners can do projects on Mathematics found in nature, in the classroom and in the home. They learn to work together in a team, listen to one another and to share ideas.

Discuss whether so called “bargains” are always bargains. What is your attitude towards “sales” in shops? Is it always necessary to give / receive birthday presents? Why do you give presents? When would not giving presents be acceptable?

  • With the inclusion of the story of the secret sign at this stage, learners are able to understand the significance of the “0” as “place holder” (indegrated with Literacy).
  • The patterns with addition and subtraction of 6, 7, 8 and 9 are emphasised.
  • Telling the time in minutes become easy as learners count the minutes in 5’s.
  • Codes are used to find the answer to a puzzle.
  • As preparation for the Christmas celebrations, the month of December is used for activities involving the calendar.
  • Module 8 concludes with a game where crackers with number sentences are matched to lights on the Christmas tree.
