### Heuristic Problem solving in Mathematics (Activity 1)

Problem
Two men facing a tall building notice the angle of elevation to the top of the building to be 30o and 60o respectively. If the height of the building is known to be
h =120 m, find the distance (in meters) between the two men.

Heuristic Problem Solving
Stage 1
Question any assumptions
Key in your assumption/s in the linoit individually.

Questions surfaced from Stage 1:

Stage 2
Solve the Problem Individually (my perspective)
Once your assumptions and hypothesis have been clarified, start working on the problem individually. No discussion with anyone for this stage.
You are the Civil and Structural Engineer and the 2 men are the land surveyors from a Company. You have to pit your skills and knowledge with engineers from other companies.

Stage 3
Collaboration - seeking multiple perspectives
In the big group of 5-6 students, present and discuss your solution with the group.
Focus on the assumptions/hypothesis, Process and the validity of the final solution(s).
Post your Group's solution as a New Post with the following criteria:
Post Title: Heuristic Solution (Group number)
Present the following:
- Process (how you solved the problem) - what method/approach you used eg diagrams, on-line resources
- Final Solution

Stage 4
Peer Assessment
Review the solution(s) from other groups.
To facilitate process, follow the following:
Group 1 to comment on Group 2
Group 2 to comment on Group 3
Group 3 to comment on Group 4
Group 4 to comment on Group 1

Stage 5
Self Assessment
