Exemplars (from the NaCCA curriculum)
Through think-pair-share: Establish the concept of logical reasoning, use it to compare statements and quantifiers, make intelligent guessing and judge the validity of logical arguments (including positive and negative statements), and ensure participation by all learners. Example: Make a declarative sentence and identify whether it is true or false. i.e. i. (False) ii. Accra is the capital city of Ghana. (True) iii. The earth is the third planet from the sun. (True) Positive Statement: Rain fell in northern Ghana today. Negative Statement: No rain fell in northern Ghana today. In collaborative and gender-responsive groups, investigate to establish truth tables, statements and connections using conjunction (And) or disjunction (Or). i.e. Logical connectives: like, and, or, not, and if . . . then, are examples of connectives. i.e. i. Conjunct 1: It is raining heavily ii. Conjunct 2: The dogs are barking iii. Conjunction: It is raining heavily, and the dogs are barking Teaching and Learning Resources: - Technology tools: - Computer, GeoGebra, Google - Search, - YouTube videos, etc - Cardboards, - measuring instruments Assessment (3.1.2.AS.1).
