codeCampus is an online training tool for teaching K-6 teachers how to teach code in their class. The first hour of training and 2 weeks worth of lesson ideas are free. I only checked out the first part of the course but it looks professional and well done. There are short videos followed by coding activities. I think this would be a good PD day activity for a group of teachers. The coding is based on using Scratch (which is also free) so this is something you can try out risk free. I would say it is best for a grade 3-6 group that has very little programming experience. If you try it out let me know how it goes.
