ALEX Lesson Plans
Subject: Mathematics (4) Title: Creative Factor Trees
Description: Students will explore and review prime and composite numbers. Students will also build a factor tree model by displaying how to write out a prime factorization of a number correctly, how to identify prime and composite numbers, and how to check their results. This handson approach allows students to use different mediums and practice their understanding of mathematics.
Subject: Mathematics (4) Title: Hanging Out with Prime Factorization
Description: During this lesson, students will review factors, prime and composite numbers. Students will also create a mobile that show the prime factorization of the number of their choice.
This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMSU Project.
Subject: Mathematics (4  6) Title: My Favorite Number
Description: The activity allows students to review many of the number theory concepts. Students will pick a composite number write verbal expressions about the number, find the factors, prime factorization, list multiples, draw a cartoon character of the number, and write a word problem. The purpose of this activity is to be a review of the number theory topics taught during middle school.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMSU Project.

Subject: Mathematics Title: Factor Game
Add Bookmark
Description: This interactive game, from Illuminations, allows students to exercise their factoring ability. They can play against a friend or the computer as they take turns choosing a number and identifying all of its factors. Thinkfinity Partner: Illuminations Grade Span: 3,4,5,6,7,8
Subject: Mathematics Title: The Product Game
Add Bookmark
Description: In this fourlesson unit, from Illuminations, students play a game in which they start with factors and multiply to find the product. They play the game, make their own game boards, use Venn diagrams to represent the relationships between the factors or products of two numbers and develop strategies for winning the game.

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: Looking for Patterns
Add Bookmark
Description: This lesson, one of a multipart unit from Illuminations, focuses on the properties of multiplication. Students skip count, examine multiplication patterns, and explore commutativity. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
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: The Factor Game
Add Bookmark
Description: In this Illuminations lesson, students play the Factor Game, which engages students in a friendly contest where strategies involve distinguishing between numbers with many factors and numbers with few factors. Students are then guided through an analysis of game strategies and introduced to the definitions of prime and composite numbers. Thinkfinity Partner: Illuminations Grade Span: 3,4,5,6,7,8
Subject: Mathematics Title: Super Bowl Scores
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students explore the connections between mathematics and football. Students analyze information about football scores represented graphically and then discuss, describe, read, and write about the graphs and the information they contain.
