Ceiling/Floor • Activity Builder by Desmos

Hi everyone!

I found this activity online and copied its first slide here. I am trying to edit the slide so that it shows Stage 0 (instead of Stage 1) when there is only one circle, then Stage 1 will be when there are 3 circles. It seems like its being controlled by a floor function built into a time variable.


Choose Edit Graph on the graph and make two changes:

Thank you.

That worked. Is there a way that the “-1” does not appear?

I am not seeing -1, but it could be that you need to restrict the slider in the graph.


Thank you so much. I need to learn how the syntax of the function definition. Thanks again.

It looks like you’re making progress with your learning already. Looking at other people’s activities is a pretty good way to study.
