Students, even as young as kindergarten, are natural problem solvers (Carpenter et al., 2017). Even before they learn to count, they can make sense of mathematical problems and real- world situations (National Council of Teachers of Mathematics, 2022). Kindergartners can make sense of complex story problems, including Separate Start Unknown problems, which involve an unknown quantity that decreases after an action occurs, resulting in a smaller quantity. This problem type is historically the most challenging of the additive problem types for young learners. This article highlights four students using tools to solve this problem type with included teacher takeaways.
