# Lesson Ideas

In Pearl Diver, players take the form of a scuba diver in a dive boat, bobbing above a shipwreck. They must dive at the proper place on various number lines to retrieve precious pearls instead of rotting old boots. They'll have to be careful not to touch an electric eel! The game starts out with simple numbers but quickly introduces more complex concepts, including negative numbers, fractions, and decimals. In between rounds, students will take a break from diving and practice estimating skills as they prepare to slice some electric eel sushi. Pearl Diver teaches number properties; plotting numbers; visualizing quantity on the number line; ordering numbers; and using the number line as a visual model for mathematical operations.
