Lesson Plan: Limits by Direct Substitution Mathematics • 12th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the direct substitution method to evaluate limits.

Objectives

Students will be able to

use the direct substitution method to find limits of constant, polynomial, radical, rational, trigonometric, exponential, and absolute value functions,
determine the value of a constant in a function given its limit at a point.

Prerequisites

Students should already be familiar with

limit notation,
finding limits from tables and graphs.

Exclusions

Students will not cover

properties of limits,
evaluating limits using algebraic techniques,
limits at infinity and unbounded limits.
