Mission and programs · 2024

Mission

The specific purposes for which the corporation is organized are to educate mathematically talented secondary and tertiary students in mathematical thinking and writing. The means of providing such education includes, but is not limited to, establishing residential summer programs for instructing such students.

Activities or mission (Part I)

To educate mathematically talented secondary and tertiary students in mathematical thinking and writing. The means of providing such education includes, but is not limited to, establishing summer programs for instructing such students.

  • MathILy: a residential summer program for mathematically gifted high-school students. Number of students enrolled was 44 in a 5-week program of courses, presentations and leisure activities. Eleven trainees (staff members) also benefitted.

    Expenses $279,613 · Revenue $210,981

  • MathILy-Er: Similar to MathILy with slightly younger students and who are earlier in their mathematical development. Number of students enrolled was 30 in a 5-week program of courses, presentations and leisure activities. Eight trainees (staff members) also benefitted.

    Expenses $139,111 · Revenue $132,953

  • MathILy-EST: A Research Experience for Undergraduates (REU) focused on beginning college students. Number of students enrolled was 9 in an 8-week program focused on a program of research, presentations, interactions with the MathILy students and leisure activities. One trainee (staff member) also benefitted.

    Expenses $110,121 · Revenue $110,947

  • FaBraC: a stand-alone course offered to students who have completed the MathILy summer program and who are interested in studying additional mathematical topics. It was determined that FaBraC would not run in fall, 2024, due to scheduling conflicts among the students who wished to participate. FaBraC will continue to be offered if enough student interest exists and scheduling is feasible.

On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those.
