Resource | More and Less: Language Supports for Learning Negative Numbers
The language that students use with whole numbers can be insufficient when learning integers. This is often the case when children interpret addition as “getting more” or “going higher.” In this study, we explore whether instruction on mapping directed magnitudes to operations helps 88 second graders and 70 fourth graders solve addition and subtraction problems with negative numbers. Further we…
