This unit teaches you how to spot patterns, understand them deeply, and represent them in different ways—words, tables, graphs, and equations. You'll also learn to model patterns using simple algorithms.

By the end of this unit, you'll be able to:

• Tell the difference between linear (constant difference), exponential (constant ratio), and quadratic (constant second difference) patterns
• Switch smoothly between words, tables, graphs, and equations to represent relationships
• Build rules from data by finding slope, starting points, and growth factors
• Model additive and multiplicative patterns using simple algorithms

📚 Lessons

Lesson 1.1 — Recognizing and Describing Patterns

Learn to identify linear, exponential, and quadratic patterns. Figure out the rule behind any pattern and use it confidently.

Lesson 1.2 — Representing Patterns Thoroughly

Master moving between words, tables, graphs, and equations. This skill helps you check your work and understand relationships on a deeper level.

Lesson 1.3 — Modeling Patterns with Algorithms

Write simple algorithms and pseudocode to model linear and exponential patterns. Connect coding logic to math concepts.
