Lego Spike Essential is for students K-4 to use Lego bricks and sensors to teach students programming concepts, circuitry, and robotics, preparing them for more advanced STEM concepts. It is the replacement for Lego WeDo. The first week of this course, a training kit will be delivered to your school or library for you to be able to complete the projects. It will be picked up on the date marked on your container. This course should take about 3 hours to complete.
