If your child or grandchild has brought home a math worksheet that looked like a foreign language, you’re part of a very large club. Modern math instruction has moved away from the memorization and “carry the one” method most adults learned, and parents nationwide are struggling to help. InvestigateTV+ Season 4, Episode 11 digs into exactly why the shift happened and what families can do about it, from asking teachers for parent-friendly explainers to using free online tools that break down each method step by step.
The same episode introduces us to Ben Hogan, a prosthetist at Mary Free Bed Rehabilitation Hospital, who created Project Bike Leg. His idea takes old bicycle parts that would otherwise be scrapped and turns them into functional prosthetic legs for amputees in developing nations. The need is staggering: more than 90% of people in developing countries who need a prosthetic leg don’t have access to one, making low-cost innovation like this genuinely life-changing.
Rounding out the episode, a Nashville company is deploying AI to recover unclaimed music royalties for artists, and 13-year-old Louisiana author Naomi DeBerry wrote “My Daddy Needs a Gift” about her father’s kidney transplant to encourage organ donation. Four stories, four reminders that creative thinking solves real problems. Which one hits closest to home for you? Let us know in the comments.
