Sequences, Time Series and Growth
Students model situations using arithmetic and geometric sequences, recurrence relations, and time series with seasonal effects.
About This Topic
Students model situations using arithmetic and geometric sequences, recurrence relations, and time series with seasonal effects.
Key Questions
- Which growth patterns are best modelled by arithmetic, and which by geometric sequences?
- How do we separate trend, seasonality, and noise in real time-series data?
- What questions can a recurrence relation answer that a closed formula cannot?

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.

Bivariate Data and Linear Models
Students investigate associations between two variables, fit and interpret linear models, and reason about correlation versus causation.

Networks and Decision Mathematics
Students represent real-world problems as graphs and apply algorithms for shortest paths, minimum spanning trees, and project scheduling.
