Context of the Standard

Objects and actions have attributes; these attributes allow people to group items. Attributes may be physical properties, behaviors, or actions. Actions in computer science are reflected in step-by-step sequences (algorithms). Actions may be categorized as back and forth movement, turning, and stopping. Categorizing of attributes or actions relies on careful observation of patterns and similarities and differences.  In this standard, students are expected to analyze groups of items and compare and contrast the attributes that led to the development of the group.

In block based programming environments, commands are grouped into categories based on function. In higher level programming languages, data are often classified by the type and format of the information.
