March is the month for State MATHCOUNTS competitions! Kudos to everyone who participated in their local chapter competitions and best of luck to all going to State!

Are you ready to level up with Olympiad training? Registration is open with early bird pricing available for our WOOT programs: MathWOOT (Levels 1 and 2), CodeWOOT, PhysicsWOOT, and ChemWOOT. What is WOOT? WOOT stands for Worldwide Online Olympiad Training and is a 7-month high school math Olympiad preparation and testing program that brings together many of the best students from around the world to learn Olympiad problem solving skills. Classes begin in September!

Do you have plans this summer?

Mathcounts STRATEGIES
Existing_Human1   19
N 11 minutes ago by Existing_Human1
Hello commuinty!

I am wondering what your strategies are for mathcounts. Please note I do not mean tips. These can be for all rounds, but please specify. BTW, this is for state, but it can apply to any competition.

Ex:
Team - sit in a specific order
Target - do the easiest first
Sprint - go as fast as possible

I just made up the examples, and you will probably have better strategies, so if you want to help out, please do

The daily problem!

N 33 minutes ago by c_double_sharp
Every day, I will try to post a new problem for you all to solve! If you want to post a daily problem, you can! :)

Please hide solutions and answers, hints are fine though! :)

The first problem is:
[quote=March 21st Problem]Alice flips a fair coin until she gets 2 heads in a row, or a tail and then a head. What is the probability that she stopped after 2 heads in a row? Express your answer as a common fraction.[/quote]

What was your Mathcounts Chant?
ilovebender   59
N Mar 17, 2025 by wikjay
Hi, I wanted to ask everyone, before the written competition, each state had to do their chant. What chant did you and your team make xd!

Im in WV and I think we did the least cringe chant, and it goes like this:

(After one person says something, the other person following waits ~2 seconds, and then says their line)
P1: Hi
P2: Hi
P3: Hi
P4: Bye

Lol if you were at the national competition you prob remember.
