Understanding Math – Addition and Subtraction is the latest Mathematics app from appp media and is the second in their Understanding Math series, based on Jerome Bruner’s Three Modes of Representation learning theory. This app explores the concepts of addition and subtraction using different symbolic, visual and active representations. As well as answering set problems, the app gives children tools to help solve their own addition and subtraction problems.
