Limits: Numerical, Graphical & Algebraic Reasoning

How can values near an input reveal behavior at that input—even when direct substitution fails?

Instructional priorities

  • Begin with multiple representations and precise language.
  • Require theorem or definition names when they govern a conclusion.
  • Use technology after a mathematical setup is visible.
  • Assess notation, units, interpretation, and verification—not answers alone.

Evidence cycle

  1. Readiness retrieval
  2. Guided concept development
  3. Pathway practice
  4. Investigation
  5. Mastery attempt
  6. Correction and reassessment

Common misconceptions

A graph can cross a horizontal asymptote. The asymptote describes end behavior, not a forbidden output. A limit is not found by merely substituting the target. Substitution works only when the function's local structure permits it.

Assessment guidance

Use the teacher keys as instructional references. Accept mathematically equivalent exact forms. Require work for formal evidence and inspect calculator or CAD settings when technology affects the result.

Printable faculty solution set

The three differentiated Unit 02 worksheets now contain 40 unique problems. Use the synchronized reasoning key and accept mathematically equivalent justified solutions. Worksheet completion never replaces 80% mastery checks.

Interactive limit investigation

Explore one-sided limits, holes, jumps, asymptotes and oscillation with the original Calculus I Limits Laboratory. This is a free study tool and does not confer a completion score.
