Subject: Mathematics (4) Title: Let's Go Shopping
Description: Students will be given a task card stating how to spend a certain amount of money. Students must look through sale papers, find the items to purchase, add the totals, multiply quantities, subtract from the total, and write a check to purchase the items.
This is a College and CareerReady Standards showcase lesson plan.
Subject: Mathematics (4) Title: Explorations in Place Value
Description: Explorations in Place Value is an interactive math miniunit that incorporates the use of children’s literature, mathematical learning stations, and small group instructional strategies to reinforce basic principles of place value and to teach students about writing large numbers in expanded notation.
This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.
Subject: Mathematics (3  4), or Technology Education (3  5) Title: "Hanging Out the Laundry" with Place Value
Description: As an introduction to the thousands place in place value, students will first practice with place value mats and base ten blocks. Then students will play "hanging out the laundry" for more practice with place value. Additional practice can be gained by accessing the website provided.

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: Further Investigating Greater Than, Less Than, and Equal To
Add Bookmark
Description: Students build upon their understanding of greater than, less than, and equal to by observing quantity and making comparison using varied instructional materials. The fish cutout, with its mouth open, represents the greater than or less than symbol; the clam cutout represents the equal to symbol. Using fish lips as a transition point, children will apply their understanding of greater, less, and equal to the standard symbols as the teacher introduces symbolic notation at an developmentally appropriate level.
