Sacramento Area Competitions in Mathematics


Welcome to SACMATH

(Last Updated: May 6, 2020)

The in-person ARML competition in May has been cancelled, but MATHLEAGUE.ORG is holding online practices for the FARML (Fake ARML, on May 16) and ARML Local (on May 30-31) competitions. Come join practices for good problem-solving experience and the online competitions.

Practices are Saturdays and Sundays from 5pm to 7pm. The practice content is the same on Saturday and Sunday, but there is enough content that students can do something different each day. The content is oriented towards students with experience in high-school-level mathematics (algebra and geometry), but there is usually a "Beginners Room" that provides a slower-paced "guided experience" with the practice content.

If you are interested in the online practices, do the following:

- Sign up for the MathLeague.Org ARML mailing list at

- Read the mailing list archive at

- Review practice schedule and content at

Hope to see you at ARML practice!

SACMATH uses tests from MathLeague.Org and MathLeague.Org has come out with a statement on Coronavirus that is a good statement of policy and status. Please read the statement for a policy and status on contests.

SACMATH (Sacramento Area Competitions in Mathematics) is an organization led by Jeff Soesbe that has been running mathematics contests in the Sacramento region since October 2009.

During the 2019-2020 school year, I am planning another series of fun and challenging contests. I will also publicize other contests and math-related activities in the region. You can join the SACMATH mailing list to receive announcements of upcoming contests and activities.

My plan is to have one contest day per month from October through March. On this contest day there would be MathLeague.Org Elementary School and Middle School Contests. I will also try to do some High School contests during the year, as time and site availability permits.


UC Davis has a Math Circle program, for math education and problem solving building, with meetings throughout the year. I am also planning to work wtih UC Davis to host the AMC competitions throughout the school year. Details are below.

I will be recruiting students to form an ARML team to representing Sacramento Valley at ARML. Practices will be Saturdays in 2020 at UC Davis, in conjunction with Math Circle. See below for more information.

Feel free to contact me (Jeff Soesbe of SACMATH) at [email protected] with any questions. 

I hope you enjoy the contests!
