Title: Become a "ruler" of the ruler!
Description: In order to practice basic sewing skills, students must be able to read and use a ruler for a variety of tasks. In this hands-on lesson, students will work collaboratively to demonstrate their mastery of how to read "English" units of measurements (inches). Students will learn how to read both 1/8" and 1/16" measurements through the use of yardsticks, rulers, and flexible measuring tape. This lesson can be used as part of a unit or as a remediation for students who will be using a ruler on assignments and projects.

Subject: Mathematics
Title: Investigating Equivalent Fractions with Relationship Rods
Description: In this lesson, one of a multi-part unit from Illuminations, students investigate the length model by working with relationship rods to find equivalent fractions. Students develop skills in reasoning and problem solving as they explain how two fractions are equivalent (the same length). Relationship rods are wooden or plastic rods in ten different colors, ranging in length from one to ten centimeters.

Title: Inch by Inch
Description: In this lesson, one of a multi-part unit from Illuminations, students use an actual ruler to represent various fractions as lengths. This lesson builds on work done in a previous lesson with nonstandard measurement as students use a standard instrument to measure a variety of items. Several pieces of literature appropriate for use with this lesson are suggested.

Subject: Mathematics
Title: Communicating about Mathematics Using Games: Playing Fraction Tracks
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.
