Subject: Mathematics (4  5), or Technology Education (3  5) Title: Please Excuse My Dear Aunt Sally
Description: As a handson lesson, the students will recognize the correct usage of the order of operations. In groups, the students will work cooperatively to discover the importance of following stepbystep instructions and apply that knowledge in solving algebraic equations by correctly using the order of operations.
This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.
Subject: Mathematics (4  6) Title: The Mean, Median, and Mode Chain Gang
Description: Cooperative learning groups and chain links are used to find the mean, median, and mode. A Science NetLinks lesson is linked for further reallife application in the world of baseball (optional). This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (3  5), or Technology Education (3  5) Title: Let's Go Shopping!

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.
