The Symmetric Property of the Equality Relation and Young Children's Ability to Solve Open Addition and Subtraction Sentences

Weaver, J. Fred

Journal for Research in Mathematics Education, 4, 1, 45-56, Jan 73

The ability of 135 first, second, and third grade classes to solve open sentences involving sums between 10 and 18 was investigated. Performance appeared to be related to grade level, operation, the position of the placeholder, and the existence of a solution within the set of whole numbers. (Author/DT)
