A teaching moment is a gameplay mechanic featured in The Sims 4: Parenthood. They are similar to chance cards and affect the children and teens of the household. Teaching moments can occur when a child or teen ask their parent for advice, or the parent gets a call from the Sim's principal during school hours about what they're doing.
For a teaching moment to pop up, a child or teen can autonomously "Ask for Advice" or have a parent answer a call from the principal from their phone during school hours. Here, the player can see what the Sim in question is asking about or what the principal is saying, given the choices given. Each choice will affect the Sim's character values. More options can be unlocked by raising a Sim's parenting skill.
