On 14th January 2018, the Fundamental Engineering Studies Programme has organized a Mathematics-oriented activity during the FKAB4Orphans Program. Of the activities held were Puzzle Hunt, involving 36 orphans from Perlis Orphan Association, Kompleks Penyayang Tun Dr. Siti Hasmah, Perlis. Puzzle Hunt involved 3 checkpoints where they have to solve: Slice Form & Wood Puzzle, Weight Balance and Paper Brigde. The outcomes from this activity were such that the students are able to identify the geometric shape and observe its application in the science field (engineering) used in daily life. The students also were trained to think analytically in solving the problem related to distance and unit conversion, understand the concept of volume, space and its application in the construction of a bridge.
