What is Camp Lemma?

Camp Lemma is a one-week summer day program for rising 5th-8th graders who love math.  Our campers learn, create, and play in a mathematically-rich environment, surrounded by like-minded peers, and guided by our expert staff.

Our Curriculum

Our activities allow students to explore a variety of mathematical topics outside the standard middle school and high school curriculum.  From polytopes, to secret codes, to probability paradoxes, we try to give students a sense of the variety of ideas that fall under the broad umbrella of “mathematics.”

Our 2022 Summer Program

This summer Camp Lemma will be an in-person, vaccine-required program, held during the week of June 20-24, in the Proof School building at 973 Mission Street in San Francisco. Camp hours are 9:30am to 3:30pm. Students should bring a lunch, and will have access to a refrigerator and microwave.

COVID Safety

Camp Lemma is committed to running a safe and joyful in-person program this summer. Campers will be required to take a rapid antigen test on Sunday, June 19 in order to attend camp on Monday, June 20. In addition, given the current rate of spread in the community, we have been asked to require campers to wear masks at all times in the Proof School building.
