Lisa takes over her first-grade classroom and learns that there’s more to teaching than just knowing facts.
At the elementary school, the first grade class is in session. The teacher, Miss Allegra, attempts to teach her students how to count, how to care for their garden, and read a story to them, but throughout it all, Lisa expresses her disdain at how soft her teachings are. Eventually, Miss Allegra gets so fed up with Lisa's interruptions, she asks her if she would like to teach the class instead, and Lisa, thinking that she can do better, accepts. After one more insult, Miss Allegra storms off, leaving Lisa in charge.
However, Lisa's methods of teaching the class are too complex for the first-graders to comprehend, as she teaches them what string theory, photosynthesis, and the anatomy of a dinosaur. On top of that, whenever Lisa tries to fulfill the student's requests, she only succeeds in making things harder for them. Eventually, when the students start to make fun of Lisa while she teaches them about dinosaur anatomy, Lisa calls for DareBot 2.0, her robot assistant, in order to help out with the rowdiness of the students. As Lisa continues to teach the class subjects they can't comprehend, DareBot 2.0 keeps the students focused by keeping them awake, and threatening to obliterate them if they don't comply with his demands. When Darcy asks Lisa if Miss Allegra is going to come back, Lisa responds by saying that she gave them more info to learn than Miss Allegra ever did, and suggests they take a pop quiz to prove it, making all the students cry. Later, as Lisa and DareBot 2.0 grade the quizzes (with each one failing), Lisa questions how she can appeal to them. While drinking from a coffee mug, Lisa sees the text on it, which reads "Teachers Bring Learning to Life". This causes Lisa to figure out what she can do.
The next day, Lisa apologizes to the class for her unsuccessful teachings yesterday. She says to make up for it, inspired by a book the students like to read called Run, Dino, Run!, she's going to show them the actual dinosaur in the story. After commanding DareBot 2.0 to activate the "dinosaur DNA wi-fi particle transfer" machine, the device brings in an actual dinosaur. When Lisa attempts to show it to the class, it suddenly roars, and the students, realizing it's the real deal, quickly run away from the classroom, just as it bursts out and starts chasing them. Lisa and DareBot 2.0 follow from behind, attempting to stop it from running rampant. As the kids run out of the school, DareBot 2.0 catches up with the dinosaur in the gymnasium, where a craft fair is being held. As the two prepare themselves to fight, the dinosaur swings its tail at DareBot 2.0's head, causing it to fly off and shut down.
With Lisa now defenseless, she attempts to run away, but accidentally gets caught in a dead end. Just as the dinosaur closes in on Lisa, Miss Allegra suddenly arrives and calls the dinosaur out. As the dinosaur begins to charge toward the teacher, she suddenly gets it to calm down by giving it a box of apple juice and playing her guitar to get it to sleep. Flabbergasted, Lisa asks how she knew she needed help, to which Miss Allegra states that she had security cameras in her classroom, and heard the students screaming. Lisa apologizes and ultimately admits that Miss Allegra's teaching methods are better, saying that connecting to the students matters more than just knowing facts.
Later, Miss Allegra is back to teaching the first graders, with the dinosaur now one of her students.
