Symbolic representations in mathematics (e.g., equations) are powerful and essential for more advanced mathematical thinking, but they cause major problems for K–8 learners. To engage mathematical reasoning without symbolic representations, BrainQuake has created diagrammatic mathematics puzzle games that provide an alternative, more learner-friendly interface to mathematical thinking and multi-step problem solving. In this working paper, we first outline the design underlying BrainQuake’s puzzle games, and we provide preliminary evidence that they can be used effectively in classroom settings. The latter part of this paper outlines a randomized control study—currently in progress—examining how BrainQuake’s suite of puzzle games impacts students’ mathematics achievement and attitudes. The results of the randomized trial will be presented at the conference. This work on the whole provides a concrete illustration of how understanding of deeper cognitive processing can be leveraged to design learning games that effectively support students in reasoning in mathematics.
