Mean (Average) of Data Sets
Calculating the mean (average) of data sets and understanding its use as a measure of central tendency.
Key Questions
- Explain what the 'average' tells us about a set of data.
- Compare the mean, median, and mode as ways to describe the 'centre' of a data set.
- Analyze situations where the mean might not be the best measure of central tendency.

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.
