Sketchy

I think that this is software is one of the best we have seen. The main reason I think this is because it is so flexible, and it can be used at almost any grade level. Kindergarten children can use it to practice their letters. Upper elementary students can use it to create timelines and animate scientific processes. I would like to use it with my middle schoolers to create political cartoons. And, I can see high schoolers using it to explain higher order math or in any number of ways.
Often, when software is promoted as being appropriate for multi-grade levels, it really isn't. Often, the teacher has to do much work to make it simpler for younger students, or more advanced for older ones. However, in this case, I think it is really the truth. Sketchy can be as simple or complicated as the artist makes it. It is easy to learn and easy to use. Students love to create things. Sketchy gives them a way to do that and motivates them at the same time.
Teachers can eay develop rubrics to grade sketchy assignments. This ensures that the students know what is expected and keeps the assignment focused. It is even more helpful when students are included in the process of rubric development.
