Around every hub there are 8 place holders where you can post nodes. Click one of the 8 circles and the node selector will appear. When you move your marker across it, you will see names and colours of the different nodes you can choose from. Click the node you want and it will place itself in the place holder. You can read a little about the function of the node in the node itself. Bear in mind that your students always work with the nodes in a hub clockwise, starting at 12 o’clock. If you want more information about the nodes, you can read here in the support pages under the headline the 10 Loops nodes or go to the learning loop Build a learning loop to see practical examples of how each node can be used.
