Increasing and Decreasing Patterns with Tables and Charts
Grade 4 patterning formalizes the connection between patterns and data: a table of values is both a pattern description and a data display. Fish stock changes over time (BC curriculum context) produce a decreasing pattern that students can represent in a table, graph on a number line, and use to predict future values. This is the beginning of mathematical modelling: using a pattern rule to describe and predict real-world change.

WHAT STUDENTS WILL LEARN
✓Represent increasing and decreasing patterns in tables, charts, and on number lines
