However, aspects of rational numbers that are incongruent with natural numbers are rarely explicitly stated in mathematics instructional material (Van Dooren et al., 2019). In a sample of middle school students, adaptive rational number knowledge substantially differed even among the top 45% of students, who all had strong conceptual knowledge of rational numbers' size, representations, and operations as well as strong procedural knowledge of rational number arithmetic. Moreover, following the constructivist game design framework, NanoRoboMath aims to engage players in exploring and experimenting with domain-relevant representations emphasized by Holbert and Wilensky (2019) to enhance their adaptive rational number knowledge.

Another type of visual model that emphasizes the measurement interpretation of rational numbers is the number line, which was used, for example, in Semideus (Ninaus et al., 2017), Motion Math (Riconscente, 2013), and Catch-the-Monster (Braithwaite & Siegler, 2020) to support players' understanding of numerical magnitudes. Kärki, T., McMullen, J., & Lehtinen, E. (2021). Items tested students' knowledge of the effects of arithmetic operations with fractions and decimals using questions, including the following: "Is the outcome of 40 × 1/3 smaller or larger than 40? " Advances in game-based learning (pp. Lesson 5: Multiple-Step Problems. In the game, players had to mix the different representations of rational numbers, and they needed a good understanding of the effects of operations to achieve high scores in power mode tasks. To confirm the effectiveness of the game, future studies would need to use an a priori power analysis that acknowledges the nested structure of the data. Intro levels consisted of two tasks (targets), while ordinary levels had four tasks, and extra levels had eight tasks. Children doing mathematics. Lesson 3-6 applying rational number operations answer key strokes. Lesson 5: Distance, Rate, and Time. Adaptive number knowledge was first considered with whole numbers (McMullen et al., 2016, 2017), but the concept has recently been extended to rational numbers (McMullen et al., 2020).

Children's counting and concepts of number. Recently, McMullen and colleagues (2020) examined students' capability to integrate multiple features of their procedural and conceptual knowledge of rational numbers in a novel task, as a means to examine a specific behavioural manifestation of adaptive expertise with rational numbers, which they called adaptive rational number knowledge.
The arithmetic and numerical skills and knowledge needed for strong adaptive rational number knowledge appear to align with features of conceptual knowledge. To examine whether NanoRoboMath could be an ecologically valid instruction tool that supports the development of conceptual and adaptive rational number knowledge in primary education, we carried out a quasi-experimental classroom intervention in which a group of students played NanoRoboMath during three mathematics lessons. A control group attended normal (business-as-usual) math lessons, which did not contain rational number instruction. Lesson 7: Dividing Integers. Moreover, to avoid including players who only repeated the first few levels, students who completed less than four ordinary levels (16 different tasks) were excluded.
