Understanding conceptual relationships is an important aspect of learning arithmetic. Most studies of arithmetic, however, do not distinguish between children's understanding of a concept and their ability to identify situations in which it might be relevant. We compared 8- to 9-year-old children's use of a computational shortcut based on the inverse relationship between addition and subtraction, in problems where it was transparently applicable (e.g. 17+11−11=□) and where it was not (e.g. 15…

Children’s strategies to solving additive inverse problems: a preliminary analysis
Prior studies show that elementary school children generally “lack” formal understanding of inverse relations. This study goes beyond lack to explore what children might “have” in their existing
Patterns of Individual Differences in Conceptual Understanding and Arithmetical Skill: A Meta-Analysis
Some theories from cognitive psychology and mathematics education suggest that children's understanding of mathematical concepts develops together with their knowledge of mathematical procedures.

Children’s knowledge of arithmetic concepts is considered critical in the development of current and later mathematic skills. If children understand numbers, operations, and the relations among them,
Childrens understanding and use of inversion in arithmetic
In this presentation, I consider the origins and the extent of children’s understanding of the inverse relation between addition and subtraction. I argue that this understanding might have its
Young children's use of derived fact strategies for addition and subtraction
It was concluded that children may have difficulty with understanding and applying the relationships between addition and subtraction.


Individual differences in children's understanding of inversion and arithmetical skill.
Two experiments are reported that investigate children's understanding of the principle of inversion and the relationship between their conceptual understanding and arithmetical skills, which indicates that they could make use of the inverse principle.

The extent to which certain information-processing demands make some problems more difficult than others and whether preschoolers use arithmetic concepts spontaneously when solving novel problems is determined.

The role of conceptual understanding in children's addition problem solving.
Results revealed that conceptual understanding was related to using order-indifferent, decomposition, and retrieval strategies and speed and accuracy in solving unrelated problems and the importance of conceptual understanding for addition development is discussed.
Children's understanding of the relation between addition and subtraction: inversion, identity, and decomposition.
It is shown that children at this age use the inversion principle even when the addend and subtrahend are the same in quantity but involve different material.
