Title: IGD: Area of a Parallelogram      Add Bookmark
Description: This student interactive, from Illuminations, helps students understand and investigate how to find the area of the parallelogram if they already know how to find the area of a rectangle. Students divide the parallelogram into pieces, arrange them together to form a rectangle, and then use the formula for the area of a rectangle to find the area of the parallelogram.

Title: Geometric Solids and Their Properties      Add Bookmark
Description: In this five-lesson unit from Illuminations, students analyze characteristics and properties of three-dimensional geometric shapes; develop mathematical arguments about geometric relationships; and use visualization, spatial reasoning, and geometric modeling to solve problems. After being introduced to shapes, they look for patterns, construct a solid, and build a shape jacket.

Subject: Mathematics
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 e-example from Illuminations contains an interactive version of a game that can be used in the grades 3-5 classroom to support students' learning about fractions. e-Math Investigations are selected e-examples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The e-examples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math investigations.

Title: IGD: Area of a Rectangle      Add Bookmark
Description: This student interactive, from Illuminations, allows students to see interactively how to find the area of a rectangle by manipulating the length of two opposite sides of a rectangle. They discover that as the measurement of the base changes, the area of the rectangle remains base times height.

Title: Investigating with Pattern Blocks       Add Bookmark
Description: This lesson, one of a multi-part unit from Illuminations, promotes problem-solving and reasoning with fractions as students investigate the relationships between various parts and wholes. It also focuses on representation as students are given multiple opportunities to investigate the relative value of fractions. Students use communication skills as they work in pairs to articulate and clarify their understanding of fraction relationships.
