Teach It Like You Stream It

You have the lessons. Here’s how to teach them.

Every worksheet on this page is free because good teaching should not depend on a budget. So is the studio I teach from. Numberbender Studio turns any laptop into a broadcast classroom — your camera beside your slides, your iPad as a live whiteboard, vertical lessons for the phones your students already hold.

  • 100% free
  • No login
  • Works on a Chromebook
  • Zoom · Meet · Teams
  • Camera beside your slides
  • iPad live whiteboard
  • Two apps at once
  • Vertical for Reels & Shorts
  • Your phone as a camera

If it works in your class, show the teacher next door. That is how this spreads — no budget, no gatekeeper, no permission needed.
