Clock Arithmetic (Modular Arithmetic)

**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.**" **Subject Competences** (the learner): "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 the forward and backward movement during operations on clock arithmetic." **Content**: "Clock arithmetic (modular/finite system)." **Suggested Activities**: "Carrying out basic operations of clock arithmetic and solving related problems; Solving word problems involving clock arithmetic." **Guidance to the Teacher**: "Use number lines as models and discuss thoroughly the steps followed when carrying out basic operations of clock arithmetic." **Suggested Instructional Materials**: "Clock faces; Circular shapes." **Suggested Competences for Assessment**: "Carries out basic operations of clock arithmetic and solves related problems."
