Coding challenges that check themselves.
Debuggle is a block coding app made for grades 3 to 5 classrooms. Kids snap blocks together, and a "Your program must..." checklist fills in as their code meets each goal. You get a dashboard that shows who is stuck, and they get real debugging tools.
Free for every classroom. By Michelle Writes... and Codes.

How it works
Three steps, and the checklist does the checking.
-
Assign a challenge
Pick a ready-made challenge or write your own. Students join with a class code and a nickname, never an email address.
-
Kids build and debug
Students snap blocks together on a stage they know. When something goes wrong, they pause, step through one block at a time, and find the bug.
-
The checklist fills in
As the code meets each goal, like "uses a loop" or "has 2 sprites," the item checks itself off. You see the whole class at a glance.
