The odds you're the first teacher ever to cover "Photosynthesis" in 6th grade are close to zero. Someone has probably already built a quiz, a labeled diagram, or a sorting game on exactly that topic — and if they published it publicly, you'll find it directly in the Community section.
What the Community is
A list of every activity its authors marked "Public" — anyone can view, play, and — most usefully — duplicate into their own account as a starting point they can then freely edit.
Searching efficiently
Community filters let you narrow by subject, grade level, and activity type. Combining all three turns a list of thousands of activities into a handful directly relevant to tomorrow's lesson.
What you see before opening an activity
Each card shows the activity type, subject, number of plays, and, for well-liked activities, a clear signal it's worth trying — you don't have to open dozens to figure out which ones are useful.
Why duplicate, not just play
You can send a public activity's link straight to your class with no changes. But most of the time, something someone else built matches 80% of what you need — duplicating gives you your own editable copy, which you tweak quickly (one extra question, a swapped image) instead of building from zero.
Contribute back
When you publish an activity as "Public" (not "Private" or "Link only"), it automatically enters the Community and becomes visible to other teachers — the same way you find activities they've created.
Before starting a new activity from scratch, a quick Community search can save the time you'd otherwise spend writing the same questions someone else already wrote.
