Use with the whole class OR as an extension/enrichment activity for that kid that always finishes before everybody else and needs an extra challenge to keep them out of your hair.

The user can follow these instructions step-by-step to build a program that calculates the mean of 8 numbers a user enters. Then there are follow-up challenges to "level-up" making the program more useful and/or extending into using similar ideas to calculate M.A.D.

Note: some familiarity with scratch programming is assumed BUT with a little guidance a complete novice can probably follow the steps (especially since scratch color codes all of its blocks making them easy to find by color).
