Lunch Lady is a game where students can practice their mental math in a practical application. Players pretend that they are the lunch lady and they need to add up three items for each student. Students click on the cash register keys to enter the full amount charged to each students account, and then they press enter. The cash register cannot be used as a calculator to figure it out. If a typing mistake is made, players can press the button marked clear to erase the incorrect answer.
The goal of the game is to correctly enter the lunch charges for 8 students within 3 minutes, before the next class comes rushing in. If the player is unable to do so, then the next students come crashing in and bump the other students, causing a big mess in the cafeteria. If a player wins, they receive a certificate!
