Professor Quigley invites Leap, Lily and Tad to the Math Factory as they wear springy shoes, while Mr. Websley is spying on them, deciding to write a math book. Professor Quigley shows the Frog Kids the numbers 0 to 10. They go to a math training area, where they see block-creatures known as Quidgets, who work with numbers by showing counting and knowing how many of something. Professor Quigley and Tad sing a song about the Quidget worm growing from 1 to 10 Quidgets.
After the song, Professor Quigley brings the Frog Kids to the Math Circus! Mr. Websley follows in their footsteps and peeks inside the tent. Professor Quigley dresses up as a ringmaster. For the first act of the show, the numbers 0 to 10 are introduced. After the act, Professor Quigley announces that there will be a 5-minute break at the ice cream stand.
At the ice cream stand, Mr. Websley is the vendor. He shows the Frog Kids about having the amount of scoops they get. Lily gets a couple scoops and tries it.
When the 5-minute break is up, Professor Quigley shows the audience an addition and subtraction act on a flying trapeze, and then counting by ten quidgets to 100. After that, Mr. Websley is shot out of a cannon across the circus and into a net. Mr. Websley and Tad conclude the video with a song. Tad gives Mr. Websley a 1-2-3-4-5, while Mr. Websley gives Tad a 6-7-8-9-10.
The scene then fades out and the credits roll.
