Calling all math detectives! We’re celebrating the 100th day of school with a new Math Mystery every week from January 25 until February 28. Solve our riddles, think creatively, and start fun conversations all about problem solving and mathematical thinking.
What is a Math Mystery?
A Math Mystery is a brain-teaser, video, or activity that invites students and parents to think about math together. Ask your child to be the detective and figure out how they want to approach and solve a problem. You’ll be amazed at the creative solutions they come up with! We’re combating math anxiety by making the problem-solving process part of the fun.
New Math Mysteries will go up every week on our Twitter and Facebook Page. But on-demand videos, lesson plans, and solutions can only be found here.
