What I expect to happen: [The student was trying to set a random interval for the size of the moon, ranging from 0.5 to 1.5]
What actually happens: [The moon would only appear when the value was a whole number scale factor.]
What I’ve tried: [not sure what to try… when the students learned dot notation, they were able to scale sprites up or down using decimals]

The randomNumber block only uses integers, so it will choose either 1 or 2 every time.

You might want to reframe it to choose between 5 and 15 and then divide that result by 10 and use that result for your scaling.

Hope this helps, but check back in if not!
