I personally think that the lessons are fine, especially for younger kids, because the kids I taught last summer were mostly younger, with the oldest being in 8th grade, and they really liked using Scratch since it was interactive and easy to follow so I would mainly use these lessons as they are for elementary to early middle school students, but the problem I had with the lessons is that some of them found them repetitive, especially the older kids, which made them uninterested and not follow along, and instead of learning or working together to achieve the objective they would just play around with the projects, so for older students I would use these lessons differently or more selectively since they need more challenge and freedom; another issue I had was that my classes were mixed with both younger and older kids, and separating them was not really an option because sometimes the younger kids wanted to do the lessons the older kids were doing while the older kids didn’t want to work with them, which made it hard to keep everyone engaged at the same time, so to fix this I would keep the main lesson the same but add different levels where everyone completes the basic task and older students have extra challenges like adding features or creating their own version, and I would also give older students more freedom by giving them a goal instead of step-by-step instructions so they can be more creative, and overall I think the lessons are good but need to be adjusted to better fit different age groups, especially in a mixed classroom.
