Arithmetic Progressions
Students study patterns in numbers to define Arithmetic Progressions (AP). They derive and apply formulas for the nth term and the sum of the first n terms.

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.

Statistics
This topic extends previous knowledge to find the mean, median, and mode of grouped data. Students learn different methods like the direct and assumed mean methods.
8 methodologies
Probability
Students explore the theoretical approach to probability. They calculate the probability of simple events like tossing coins, rolling dice, and drawing cards.
