Part B: Project (Application Task)
Select a practical task that applies the concepts learned in this module. The task should demonstrate your ability to use numbers, factors, GCD, LCM, or integers in solving real-life problems.
Examples of suitable projects include:
- • Creating a simple household or business budget using integers and operations
- • Solving sharing or grouping problems using GCD and LCM
- • Designing a timetable or schedule using multiples and factors
- • Analyzing quantities in a real-life scenario such as shopping or transport
Instructions:
- 1. Clearly describe the problem or situation
- 2. Show all calculations and steps taken
- 3. Explain how the mathematical concepts were applied
- 4. Present your final solution clearly
- 5. Consult your coach where necessary
Submission
Part C: Training Others (Peer Learning)
This section helps you strengthen your understanding by teaching another learner.
Instructions:
- 1. Select at least one concept from this module (e.g., GCD, LCM, integers, or factors)
- 2. Explain the concept to a peer or study partner
- 3. Guide them through at least one example
- 4. Ask them to solve a similar problem and support them
- 5. Reflect on your experience
Reflection:
- • What concept did you teach?
- • What challenges did you face?
- • What did you understand better after teaching?
- • What areas do you still need help in?
Submission
Part D: Assessment (Performance Review)
Assessment helps track your progress and identify areas that need improvement.
Competency Level Scale:
1 = Expectations not met
2 = Expectations partially met
3 = Expectations satisfactorily met
4 = Expectations excellently met
Assessment:
Self-Assessment: _
Coach’s Assessment: _
Assessment Focus:
- • Understanding of number concepts
- • Accuracy in calculations
- • Ability to solve real-life problems
- • Proper use of mathematical procedures
- • Clarity in explanation
Guidance:
- • If you score 1 or 2, revise and seek support
