Activity 1 Problem solving heuristics
Here is a simple Mathematical problem.

There are 28 students in your classroom. 
On Valentine's Day, every student gives a valentine to each of the other students.

  1. There is a pattern in the question

    Person 1: Exchange with 27
    Person 2: Exchange with 26 (As it exchanged with no.1 already)
    Person 3: Exchange with 25
    Person 4: Exchange with 24
    Person 27: Exchange with 1 person

    Answer will be:
    1+2+3+4...+27 = 378
    27x14(14 sets) = 378

    Answer: 378 valentines are exchange
