The lesson plan below implements elements of universal design described throughout this website.
Lesson Overview 

Unit  Exponents 
Subject  Developmental Algebra 
Lesson Description for Day  Write numbers with exponents and evaluate numerical expressions that contain exponents. 
Standards: NCTM  Understand numbers, ways of representing numbers, relationships among numbers, and number systems. 
Goals 

Unit Goals  Students will perform operations using real numbers and variables:
Evaluate numerical expressions that contain exponents 
Lesson Goals  Students will understand:

Methods 

Anticipatory Set  Show the student a Rubik’s Cube. Ask if anyone has ever tried to solve a Rubik’s Cube. Tell the students that according to the manufacturer, there are 43 quintillion different possible moves on the Rubik’s Cube. Show the number for 43 quintillion: 43,000,000,000,000,000,000
Discuss the problem of writing such large numbers and explain that there is a much simpler way to do it, and that is to use exponents, or scientific notation. The way to express 43 quintillion in scientific notation is 4.3 x 10 (with an exponent of 19). That means 10 multiplied by itself 19 times. 
Introduce and Model New Knowledge 

Provide Guided Practice  Provide students with practice problems where they must write expanded multiplication problems in exponent form and problems where they must evaluate, or solve numbers written in exponent form. Students may benefit from working in pairs to solve these problems. 
Provide Independent Practice  Assign homework from text. Direct students to use the http://usablealgebra.landmark.edu website as a reference and a place where they can have more guided practice.
