About This Topic

Students explore compound inequalities involving 'and' and 'or' statements. They extend this knowledge to solve absolute value equations and inequalities.

Key Questions

  1. What is the difference between an 'and' and an 'or' compound inequality?
  2. How does absolute value relate to distance on a number line?
  3. How can we graph the solutions to absolute value inequalities?

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.
