Storyboard of New Topic

Jaco and I would like to change the topic of final project to ‘Reduced Bearing” which is part of DIRECTION in Form 1 Geography. Students easily forget how the directions are measured from the north or the south in reduced bearing and cannot express the direction correctly, such as, NxoE, NxoW, SxoE and SxoW ( 0 < x < 90 ). The storyboard of the our new topic, Reduced Bearing can be found in the following link:
