Last week in our elementary classes we were teaching when to use 'a' and 'an'. For example, "This is a book", or "This is an orange".
Quite simple but I wanted something to make the point more exciting, and more fun, and ultimately more memorable so I created a simple printed course with a slider that the children could use to send an ozobot to either 'a' or 'an' depending on the given noun.
