mBot: Iteration in Practice

In this lesson, students will enhance their understanding of looping algorithms. The project in this learning activity is to create a “Jumping Bear” animation in mBlock. The act of jumping up and down is a set of repetitive motions, and therefore, students need to address and properly define loop bodies. This activity uses the PRIMM approach. First, students will predict the function of the demo program and then run it to see what actually happens. Students need to investigate how the demo program works and modify the demo to add some new effects to the demo program. Building on the hand-on experience, students are encouraged to make their own projects to demonstrate their understanding of this lesson.
