My Take
This is a great app for teaching coding to elementary students. The app takes place in a warehouse environment. The game is similar to those toy grabber machines at arcades and restaurants. Students need to program the grabber. Caution: this app can be confusing to some students.
How I Use It
My fifth graders love the challenge. They learn to problem solve and plan what to do beforehand. I learned to pair the students up to help each other during confusing parts. They do become addicted.
