How to stand out in math?

How can I demonstrate my interest and ability in mathematics in high school? I am aware of summer camps and math competitions such as the AMC, but I just want to make sure I’m not missing anything. Thanks!

Some ideas (to the best of my ability):
• Mu Alpha Theta/ Math National Honor Society : if you don’t have one, start one at your school
• Taking math courses at your local community college
• Excel at math
• Score well on SAT 2 Math level 2 test
