This is a link to the digital technologies website. This resource is useful because it describes what binary is, and the resource was created particularly for professional development, as it can easily be shown in a staff or year level team meeting. It includes a short video and the resource has other activities to teach students about binary. The video includes an activity that displays how to convert numbers into binary. This can be a good activity for older students. Students can be handed a piece of paper with dots representing normal numbers e.g 2,4,8,16 and then in groups work together and write down what binary number they think it is. This activity can be set up so when students have the number they move onto the next set of numbers.
