Boston-based BlocksCAD is a STEM education technology company offering a web-based 3D design platform that combines 3D modeling and block-based coding to help students in Grades 3-8 have fun learning math, computational thinking, and coding. See this summary. The BlocksCAD platform is free to use, and parents can help kids get started with projects here. The BlocksCAD team offers courses through Newton Community Education (formerly in person and these days online) as well as their own online courses. Each BlocksCAD online course runs once a week for four weeks, 5PM-6PM — on Mondays or Tuesdays for Grades 3-5, and on Wednesdays or Thursdays for Grades 6-8. As conditions permit, BlocksCAD plans to offer in-person, one-week summer day camps for Grades 3-5 (1:30-4:30PM, June 29-July 2) and Grades 6-8 (9:30AM-12:30PM, June 22-26).
