When I walked in the classroom, the first graders noticed that I did not have my computer cart with me. They got really excited when I told them about our screen-free activity involving a purple or blue mouse. The robot mouse is always a fun and engaging introductory activity to programming for my youngest students. Students develop critical thinking skills as they figure out step by step commands to help their mouse get to the cheese. Definitely lots of trial and error but the first graders were determined!
