Copy Cat
Pupils examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.
Curated OER
Function Tables
Students practice representing problems found in the real world in terms that can be translated into mathematical expressions. The situations are represented in tables and graphs by students.
Curated OER
Relationships and Functions
Fifth graders describe patterns as relations and functions. In this patterning lesson, 5th graders analyze and continue patterns. Students understand how patterns relate to relations and functions.
