According to Stem.org.uk, playing mathematics games encourages strategic thinking, problem solving and develops fluency. And according to texthelp.com, technology provides dynamic opportunities for instruction in math and STEM classrooms. Making math (or STEM subjects) visual goes beyond student engagement; brain research indicates it to be integral to learning maths. According to Jo Boaler and the team at Stanford Graduate School of Education’s youcubed, representing all mathematical concepts visually, and including visual activities at all grade levels, can greatly help students. Technology provides additional opportunities for learners to see and interact with mathematical concepts. Students can explore and make discoveries with games, simulations and digital tools. Increased access to technology for math allows for a more customized learning experience. Because no two learners are exactly alike, technology can provide individual students with content and supports that are particularly helpful to their individual needs. SumQuest is an addition-based game designed with the aim of boosting mental maths ability. There are numerous versions of the game which can be played and which cater for various age and skill levels.
