Here is a series of 5 short (3 minute) videos from Pursue God that would be good for starting discussions and introducing lessons on proverbs: Proverbs for Kids
Each video has a lesson, some with simple games or crafts, and all have coloring sheets.
CAUTION: as with most lessons on the Proverbs, these five video lessons tend to be works based rather than grace based. And kind of moralistic..... A good starting point for conversation, maybe?
