Objectives :
- Determine common factors and HCF by listing all factors of both numbers
- Develop strategy, reasoning and problem solving skills
Lesson :
Through various problems, students discover how we are using common factors in many situations, and the knowledge of these may or may not make real life problem solving easier. Since we already intuitively do this many a times, the terminology of common factors and HCF has been kept subtle and is not the focus of the lesson. The focus is on building class discussion, listening to perspectives and problem solving strategies.
The lesson plan and the worksheet used is attached below.
