Getting Unstuck was a 21-day learning experience in July 2018 of small Scratch programming challenges for K–12 teachers. It now offers useful resources like a strategies list and challenge archive. Getting Unstuck is a project of the Creative Computing Lab at the Harvard Graduate School of Education. (Text adapted from About Getting Unstuck).

Create a project that involves the touching color blocks in the Sensing category (i.e., touching color? and color is touching?). For example, you could have a sprite moving around on a colorful background, with the sprite behaving differently depending on which color it is touching, like in a maze game.
Find a project that uses broadcasting and remix it. For example, you could remix this pass-it-on project that we started.
Create a project that uses the cloning features of Scratch. For example, you could make a project that represents a natural or human-made phenomenon.
