Instructions
Socialize with other Sims until you become friends with them. Select positive social interactions such as "Ask about day" or "Tell joke." It takes just a few minutes of talking to make friends with a Sim.
Select "Talk About" when you are friends with a Sim. Select "Ask for donations." If a plus sign appears above your Sim's head, you received a donation. Repeat this process with other Sims until you have five donations.
Go to the town and select an empty land plot. Click on the sign on the plot. You are asked if you want to build a preschool. Select "Yes," and the preschool appears automatically. You do not need to use your own money to build the school.
