Meet Zipline: The Tool Helping Teachers Close the Math Gap and Reignite Joy

By Donny McChesney, CTO 

Feeling overwhelmed by your students’ struggles in math? You’re not alone. More than ever, teachers are facing challenges that stretch beyond academics—social pressures, pandemic aftershocks, and growing disengagement in the classroom. 

But there’s one issue that affects everything else: the growing math ability gap. Research shows that over 40% of students need math instruction below their current grade level. With nearly half the class requiring personalized attention, teachers feel overwhelmed, and students struggle with tasks for which they are not yet ready. This mismatch leads to poor grades, low confidence, and a sense that school just isn’t for them. So what can we do? Here’s what every teacher needs to know—and how one simple tool can make a major impact. 

Tricks Every Teacher Needs to Know When Helping Their Math Students 

Supporting students across a wide range of skill levels may seem impossible—but it doesn’t have to be. The right strategies (and tech) can bring relief, clarity, and even joy back to teaching.

  • Acknowledge the Gap: Recognizing that ability levels vary widely—even within a single classroom—is step one.
  • Avoid One-Size-Fits-All Lessons: Personalization is essential when students are starting from such different places.
  • Use Data to Drive Support: Real-time feedback helps you identify who’s ready for more and who needs foundational help.
  • Empower Students with Instant Wins: Gamified learning can increase engagement and rebuild self-esteem.
  • Let Tech Do the Heavy Lifting: The right tool can reduce prep time and amplify your impact.
