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 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: 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.
