AMO case studies

AMO · Put your knowledge to work in context.

The American Mathematics Olympiad (AMO) is a competition built around non-routine problems rather than routine computation. According to the organiser's page, AMO is an affiliate of Math Olympiads for Elementary and Middle Schools, USA (MOEMS), which the page describes as one of the oldest and most established primary and secondary school math competitions in the world, and the Singapore International Math Contest Centre (SIMCC) is the main organiser of AMO in ASEAN and Hong Kong, working with local Country and Territory Partners. The contest is offered by grade level from Grade 3 (Primary 3) through Grade 8 (Secondary 2), so a candidate sits the paper for their own grade band. The stated goals are to stimulate enthusiasm and a love for Mathematics, introduce important Mathematical concepts, teach major strategies for problem solving, develop Mathematical flexibility, strengthen Mathematical intuition, and foster creativity and ingenuity. The AMO case studies are 5 cases and about 2,647 words.
