The ABACUS International Math Challenge was launched in 1997 by Tivadar Diveki, head of Grace Church School’s science department. The program is based on a printed journal for gifted students, originating in Hungary over 100 years ago. Participants over the years included Edward Teller, Leo Szilard and other notables in physics, computer science and mathematics. Today’s Abacus 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.
The Internet has made this program available to students around the world. 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. 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.
The 16th Annual Abacus International Math Challenge runs from September, 2012 through April 30th, 2013.
In your first e-mail, please indicate your name, your grade/age, the name of your school, and the city where you live. Make sure that you indicate the number of the problem you are responding to. For proper identification, every e-mail you send should include your name.
Showing your solution:
The solution to a problem should include the results and your reasoning. Make sure that you try to find all the possible solutions for a problem. Your reasoning has to be given in English, but do not be discouraged if English is your second language. If we have a question about your answer, we will contact you.
Try to send your answers by the last day of the month for the posted problem, however solutions to any of the problems will be accepted until April 30, 2013. (You are welcome to participate in higher grade groups by solving their problems.)
You get five points for a thorough solution with reasoning; fewer points for a partial solution or solution with no reasoning, and more points if you find additional different solutions or prove more than required.
You may earn extra points if you design your own problems and they get posted in the challenge. So, try to make up some problems and solve them.
ARE YOU READY? IF SO, LET’S GO!
