General Information

Math Challenge is a free enrichment program for all Blackwell Elementary students. It is designed to help students strengthen their problem-solving skills in a fun and engaging way.
The challenges introduce strategies such as drawing a picture or model, making an organized list, looking for a pattern, working backward, and using guess-and-check.
  • There will be 15 challenge sets, released every other week from late September through May.
  • Each set contains 10–18 problems, arranged by difficulty, so students from all grade levels can participate.
  • All students in grades K–5 are encouraged to join.
  • Announcements about new challenges and due dates will appear in the PTSA Newsletter and The Blackwell Beat, and are also listed below.
Students who complete their challenges in Microsoft Forms may be recognized and rewarded for participation. To qualify, please email a screenshot of your auto-graded results to [email protected] before the due date.
Parents can find program updates in the PTSA Newsletter and The Blackwell Beat.
