This intervention is essentially a simple number board game that helps students with early number sense, typically students in pre-school or similar age programs. Complete steps, as well as a game board, can be found at the aforementioned link at InterventionCentral. This game takes 12-15 minutes per individual player and is very simple to implement with the instructions at the above link. The below resource, with a link to access to actual research, goes into the development of the game and how it can be effective for low-SES preschool students, who may have had only limited exposure to mathematics or math intervention and have thus not developed an early number sense. For these students, even a simple intervention such as this can have large effects that will help reduce the risk of later difficulties in math.
