Mathematicians go on a virtual shopping trip in an interactive designed to boost the concept of estimation. Scholars read and answer five questions—multiple-choice, true or false, and a discussion—with help from a drag-and-drop shopping...

Commutive and associative properties are the focus of a five-question interactive. Dealing with decimal multiplication and addition, mathematicians solve multiple-choice and true or false questions using a model that moves balloons along...

An interactive challenges scholars to subtract mixed numbers. Pupils answer questions—multiple-choice, fill in the blank, and true or false—with help from virtual fraction strips. The practice closes with a discussion.
