ALEX Lesson Plans
Subject: Mathematics (5  6) Title: Decimal Dilemma: Carlos the Centipede needs to buy tennis shoes!
Description: In this lesson, Carlos the Centipede must buy new baseball shoes. His dilemma will be how to multiply decimals (money) by multiples of 10. To add to the dilemma, Carlos' baseball team needs to buy shoes too! Students will multiply decimals by 100. Students will investigate what is happening to the decimal point each time a decimal is multiplied by a multiple of 10.
Subject: Mathematics (4  5) Title: Pacaderms, Pennies, and Pasta
Description: After learning of a historical event in which elephants were used to test out the Brooklyn Bridge, students construct their own bridge using very basic materials. Students weigh different items to determine the weight their bridge can withstand without collapsing.
Subject: Mathematics (5  6) Title: Decimal Dilemmas: Carlos the Centipede is Adding Decimals!
Description: In this lesson, students will work in collaborative/cooperative groups to understand adding decimals. Students will use decimal grids to represent the sum of decimals. Emphasis is on using placevalue, lining up the decimals and bringing the decimal down. Students will understand how important estimation of decimals is in reallife situations.
Subject: Mathematics (5  6) Title: Decimal Dilemma: Carlos the Centipede is Subtracting Decimals!
Description: In this lesson, students will work in collaborative/cooperative groups to understand subtracting decimals. Students will use decimal grids to represent the difference of decimals. Emphasis is on using placevalue, lining up the decimals and bringing the decimal down. Students will understand how important estimation of decimals is in reallife situations
Subject: Mathematics (5  6), or Technology Education (6  8) Title: Satisfy Your Vacation Hunger!
Description: Students will prepare and present a group project detailing the menu for a 5 day vacation. Each group will select a vacation destination and describe activities involved in the vacation and the meals that will be served. Groups will be given a budget of $200 for the 5 days of meals for 4 people. Students will use various forms of technology to research needed information, prepare the budget, and to present the final product. Projects will be turned in as a binder with required information and as a multimedia presentation to be shared with the class.
Subject: English Language Arts (6), or Mathematics (3  5) Title: "All in the Family"
Description: A cooperative unit where students work together and use a variety of math skills to establish budgets and compare and compute the best buys. Students will continue practicing their writing skills by writing thank you notes to local merchants.
Subject: Information Literacy (K  12), or Mathematics (4  5), or Technology Education (3  5) Title: Dream Vacation
Description: This unit teaches students to plan a trip with an itinerary, remain within a budget, and work cooperatively. It is a technologybased project that combines a study of mathematics, economics, geography, and social studies.

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: Language Arts,Mathematics Title: Numbers and Language
Add Bookmark
Description: In this fivelesson unit, from Illuminations, students participate in activities in which they focus on the role of numbers and language in realworld situations. Students discuss, describe, read, and write about numbers they find in familiar realworld situations. An emphasis on using components of language helps students build a broader vocabulary of numbers than the traditional symbolic representation of numbers.

Subject: Mathematics Title: Finding Products
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students examine the role of commutativity and the multiplicative identity, play a multiplication game, and explore products where one of the factors is 6. They also create a personal multiplication chart. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
