The Hopscotch app (iOS only) has long been a favorite for my student coders. They have lots of tutorials, and the students who participate in a couple of those often ask if they can code their own projects after learning the basics. If you have some iPads in your classroom, you may want to let some or all of your class try the “Carve a Pumpkin with Hopscotch” tutorial.
It’s best if you can allow pairs of students work at their own pace, rather than try to keep the whole class on the same steps at the same time. Keep in mind that the app has been updated a couple of times since this tutorial was made, so some of the tools may be slightly different.
