I built Money Math Duel for my daughter who is in second grade and learning currency. I wanted a way for her to practice adding up coins and dollars to get more familiar with making change or paying for items.
Customize each side to make it easier or harder depending on the player. This is a great way to equalize the playing field if one player is stronger than the other. For example, one player can adjust their settings to only generate questions between $15 and $20, while player two can adjust their settings to only generate questions between $0.01 and $1.
