Two Brookline HS seniors, Yuen Ler Chow and Elena Su, have created Brookline Codes to offer free online courses in math (four levels) and introductory computer science (in Scratch, Python, and Java) for greater Boston students in Grades 2-8 (and sometimes Grades K-1). Each course will engage students in two weekly sessions of 45-60 minutes each, plus off-line study. Register by September 11 for fall courses running September 14 to December 13. High school and college students may apply to teach with Brookline Codes. For more information, email brooklinecodes@gmail.com.
