This paper discusses the development and implementation of a digital game with a focus on the multiple representations it allows learners to interact with. A case study approach was adopted to examine two third-grade students’ mathematical practices as they played the game in which they needed to help an alien farmer called Gleeb to solve subtraction word problems. There are five levels to this game with all levels requiring working with three different representations: a game board, a bar model, and a number sentence. Students first represent problem situations using these multiple representations and then solve the initial problem. As the participating students progressed through the game, they engaged in important mathematical practices about subtraction and multiplication. They also successfully related the quantities involved in subtraction word problems to each other.
