Make sure you follow these steps, as they'll help you clarify or even understand the problem that might be happening.
There are several reasons why an exercise might not show up as correct when you click the ▶ button.
1. Check that your solution is correct
As a teacher, you can always check the Instructions on the left side of the screen to confirm the answer.
For certain exercises, you can also check the solution by clicking the View Solution button.
2. Check for hidden blocks
In some games, the play area is quite large, and it's possible that some blocks you used in your game end up "hidden." In this situation, the exercise won't show up as correct, so we suggest using the horizontal and vertical navigation bars to look for any blocks that might be missing.
Alternatively, you can click the broom button at any time, which will make all missing blocks reappear on the main screen. Once you've deleted them, you can try confirming your blocks again by clicking the ▶ button.
3. Restart the exercise
If the exercise still isn't validating, you can use the Restart exercise button to reset it completely — this clears blocks and sprites, and takes you back to the start as if it were your first time playing. This lets you redo the exercise from scratch and more easily spot where you might have gone wrong.

As a last resort, and if our team asks for more information, you can send a screenshot of your computer's console. To do this, you need to right-click and then click Inspect.
Then, click Console and finally take a screenshot.
