My Take
I love this! The students are highly engaged and learning. The website offers lots of teacher supports and materials. The only concern is the interface with Clever can be complicated so I don't recommend building your classes through Clever. Take the time to do it manually so you can make changes if necessary. Overall, this is a wonderful and engaging teaching tool for coding. I highly recommend it.
How I Use It
I am using this to help advance and reinforce my students' understanding of coding. It is highly engaging! In hindsight, I should have explored it more myself so that I could turn off certain features before the kids got further ahead. I recommend that teachers take the time to fully explore the sight and all the information before starting this with students.
