This two-week unit introduces students to more sophisticated number patterns and teaches students how to describe the relationship between two sets of data in a table. In the unit, students will identify patterns in everyday situations, record those patterns in the form of a table, and begin to use arithmetic expressions as well as other strategies to describe relationships between sets of data in a table. The performance task will ask students to create tables comparing age relationships. Students will describe the relationship between sets of data in each table using both written and verbal communication
