Categories & Contacts
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, 2015. (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.
