ALEX Lesson Plans
Subject: English Language Arts (3), or Mathematics (3) Title: A Math and Language Arts lesson: Introduction to Division
Description: The lesson will help students develop an initial understanding of division and clarify how the four operations of addition, subtraction, multiplication, and division relate to and are separate from each other. The lesson begins with a brainstorming discussion which builds background and fosters comprehension. A big book, The Doorbell Rang, by Pat Hutchins, is used along with manipulatives to provide instruction at concrete and pictorial levels. Students will demonstrate what they have learned by writing a short story incorporating simple division.
Subject: Mathematics (3  5), or Technology Education (3  5) Title: Let's Go Shopping!
Description: This technologybased lesson provides students practice in collecting and organizing data through the use of grocery store circulars.
Subject: Mathematics (3  5), or Technology Education (3  5) Title: It’s My Party!
Description: Students will learn the value of money by planning their own birthday party. By using the Internet and a calculator, students will be given the opportunity for a practical reallife opportunity to solve a problem related to money exchange.
Subject: Mathematics (3  4) Title: Budgeting for the Oregon Trail
Description: As a part of the online collaborative unit, Westward Ho!, students will work in cooperative groups of 45 students to decide what items they need to take on the Oregon Trail, determine the cost of the items, and complete a ledger to inventory (keep up with) items used on the trail. Information will then be used as part of a multimedia slideshow journal describing the journey.

Subject: Language Arts,Mathematics Title: Multiplying Meanings
Add Bookmark
Description: In this eightlesson unit, from Illuminations, students explore the many meanings of multiplication (skip counting, repeated addition, sets, arrays, number line, cross products of sets and balanced equations). They also learn about the order property, the multiplicative inverse and the results of multiplying by 1 and by 0. In addition, students write story problems in which the operation of multiplication is required. Opportunities to connect with literature are presented in four of the lessons.

Subject: Mathematics Title: Concentration
Add Bookmark
Description: This student interactive from Illuminations allows students to play the classic game of Concentration by themselves or against a friend. The interactive can be used to review numbers, shapes, multiplication facts, fractions, decimals, and percents. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2,3,4,5
Subject: Mathematics Title: Bag the Beans
Add Bookmark
Description: In this Science NetLinks lesson, students work with manipulatives (beans) to create and solve math problems, some of which have more than one correct answer. This lesson addresses the common misconception that there is only one correct way to solve any math problem. Thinkfinity Partner: Science NetLinks Grade Span: 3,4,5
Subject: Mathematics Title: Product Game
Add Bookmark
Description: This interactive game, from Illuminations, exercises students skills with factors and multiples. Players take turns moving a marker along a number line to create products, which are then colored in on the game board. The object of the game is to get four squares in a row.

Subject: Language Arts,Mathematics Title: Modeling Multiplication with Rows and Columns
Add Bookmark
Description: This lesson, one of a multipart unit from Illuminations, encourages students to explore the array model of multiplication. Students make arrays with counters and then create a second concrete example of the array model using toothpicks. They also write problems that involve multiplication. A children s book is suggested to connect multiplication with children s literature. Several pieces of literature appropriate for use with this lesson are suggested.

Subject: Mathematics Title: Multiplication Stories
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students practice memorization of multiplication facts where one factor is 6 or 7. They create multiplication stories, play a multiplication game, and then record their current level of mastery of the multiplication facts. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: Times Six, Times Seven
Add Bookmark
Description: In this sixlesson unit, from Illuminations, students who have previously studied the meanings of multiplication use its properties to help them memorize the products to 70, where 6 or 7 is a factor. Retention is fostered through class discussions, preparation of a personal multiplication chart, and game playing. The unit is most appropriate for students who understand the process of multiplication and have mastered the multiplication facts through the 5 table.

Subject: Mathematics Title: Clothing Sizes
Add Bookmark
Description: This reproducible worksheet, from an Illuminations lesson, prompts students to analyze measurements of their body, specifically as they relate to clothing sizes. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: A Brownie Bake
Add Bookmark
Description: This lesson, one of a multipart unit from Illuminations, focuses on student organization, preparation, and presentation of some simple foods as a way to apply various mathematical concepts, with problemsolving techniques being a central theme. Students prepare, after determining minimum amounts of ingredients required, a commercial brownie mix and serve equal portions to all class members. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: The Variable Machine
Add Bookmark
Description: This Illuminations lesson provides an introduction to the use of variables. Students explore the idea of variable as a symbol that can stand for any member of a set of numbers, and they substitute numbers for variables (letters) to discover unknown values.

Subject: Mathematics Title: Number and Operations Web Links
Add Bookmark
Description: This collection of Web links, reviewed and presented by Illuminations, offers teachers and students information about and practice in concepts related to arithmetic. Users can read the Illuminations Editorial Board's review of each Web site, or choose to link directly to the sites. Thinkfinity Partner: Illuminations Grade Span: K,1,2,3,4,5,6,7,8,9,10,11,12
Subject: Mathematics Title: Communicating about Mathematics Using Games: Playing Fraction Tracks
Add Bookmark
Description: Mathematical games can foster mathematical communication as students explain and justify their moves to one another. In addition, games can motivate students and engage them in thinking about and applying concepts and skills. This eexample from Illuminations contains an interactive version of a game that can be used in the grades 35 classroom to support students' learning about fractions. eMath Investigations are selected eexamples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The eexamples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the eexamples are natural companions to the iMath investigations. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: Factorize
Add Bookmark
Description: This student interactive, from Illuminations, allows students to visually explore the concept of factors by creating rectangular arrays with an area equal to the product of the factors. They can choose whether or not to use the commutative property when identifying factors. Thinkfinity Partner: Illuminations Grade Span: 3,4,5,6,7,8
Subject: Mathematics Title: Making Your First Million
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students attempt to identify the concept of a million by working with smaller numerical units, such as blocks of 10 or 100, and then expanding the idea by multiplication or repeated addition until a million is reached. Additionally, they use critical thinking to analyze situations and to identify mathematical patterns that enable them to develop the concept of very large numbers.
