它是什么？

A flexible ball with finger holes.

它在哪里找到？

Bring your own, or Classroom Professionals might have one.

我该如何使用它？

Use an Oball for activities where students pass a ball to each other (a name game, etc). This kind of ball is much easier to catch because of the holes/texture and its flexible design. Be mindful of age. This tool can come across as a bit babyish, so you’ll need to introduce it in the right way or decide if it’s the right tool for your students.
