Paul Erdős International Math Challenge
The ABACUS International Math Challenge (http://inside.gcschool.org/abacus/) was launched in 1997 by Tivadar Divéki. In September,2015, we proudly changed the name of our program to Paul Erdős International Math Challenge. This program is designed for students of all abilities and demonstrates that mathematical talent can be stimulated and developed through individual attention, instant feedback and challenging subject matter with flexible levels of difficulty.
Every month, eight problems are posted for each of three age groups:

Students are asked not only to solve the problems but also to present the reasoning in their solutions in English. If a student submits an incorrect solution or is simply having trouble with a problem, a teacher will offer hints as to how to go about solving the problem, giving students multiple chances to succeed.
We give five points for a thorough solution with reasoning; fewer points for a partial solution or solution with no reasoning, and more points for additional different solutions or for proving more than required.
Participants may earn extra points if they design their own problems and they get posted in the challenge.
The annual Paul Erdős International Math Challenge in this academic year runs from September 2017 through April 30th, 2018.
We are always looking for volunteer correctors, and organizations we could work with to spread the word around the world about our efforts.
