Measures of Central Tendency: Mean

Students will calculate the arithmetic mean for a given set of data and understand its significance.

Key Questions

  1. Justify why the mean is a useful measure of central tendency.
  2. Analyze how an outlier affects the mean of a data set.
  3. Predict the mean of a small data set without formal calculation.

lesson plan

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 planner

Math 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.

rubric

Math 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.
