Deep Sea Duel is an engaging game for students to learn addition with multiple single or multi-digit numbers. Students can play against each other or against the computer. They can control the number of numbers to choose from and the level of difficulty (adding negative numbers or decimals). The goal is to be the first one to pull three numbers over to your beach, which add up the the target number, which is shown on the seashell. A sum of any three numbers on the beach can total the target number.
Bonus: This game is available in both English and Spanish.
