Operations on Integers

**Background**: "An integer is a whole number (not fraction) that can be positive, negative or zero. In this topic, learners will master the concept of integers which will help them to determine a location within a group. Clock arithmetic (modular/finite arithmetic) is introduced at this level." **Learning Outcome**: "The learner recognises, manipulates and applies the knowledge of integers in real life." **Subject Competences** (the learner): "Solves problems involving the application of integers; Carries out basic operations (addition, subtraction, multiplication) of clock arithmetic and solves related problems; Solves word problems involving clock arithmetic." **Language Competences** (the learner): "Describes integers; Describes real life situations where integers are applied; Describes the forward and backward movement during operations on clock arithmetic." **Content**: "Integers; Clock arithmetic (modular/finite system)." **Guidance to the Teacher**: "Review P6 work on integers. Let learners research various areas such as marketing, sales, banking and science for ways in which positive and negative integers are used. Use number lines as models and discuss thoroughly the steps followed when carrying out basic operations of clock arithmetic." **Suggested Instructional Materials**: "Mathematical ruler; Circular shapes; Floor; Ladder; Clock faces." **Suggested Competences for Assessment**: "Solves word problems involving integers; Carries out basic operations of clock arithmetic and solves related problems."
