“…Maintenance (i.e., the ability to use acquired skills without relearning; Alberto & Troutman, 2009) in mathematics is particularly crucial as domains of mathematics are interconnected across grade levels and mathematical skills need to be applied in everyday life (Common Core State Standards Initiative [CCSS], 2019; Saunders et al, 2018). For example, elementary students learn mathematical concepts such as counting, operations, and fractions, whereas secondary students build on these basic concepts to learn more advanced mathematics (e.g., ratios and proportional relation, algebra, and modeling; CCSS, 2019; Powell et al, 2013).…”
