Subject: Mathematics Title: Expanding Our Pattern Block Fraction Repertoire
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students expand the number of fractions they can represent with pattern blocks by increasing the whole. Instead of representing the whole with one yellow hexagon, the students explore fractional relationships when two, three, and four yellow hexagons constitute the whole. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: Investigating Equivalent Fractions with Relationship Rods
Add Bookmark
Description: In this lesson, one of a multipart 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. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: More Fun with Fraction Strips
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students work with fraction strips to compare and order fractions. Building on work done with fraction relationships in a previous lesson, students develop skills in problem solving and reasoning as they make connections between various fractions. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: Making and Investigating Fraction Strips
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students make and use a set of fraction strips to represent the length model, discover fraction relationships, and work with equivalent fractions. They then create a virtual set of fraction strips using an online interactive activity. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: Inch by Inch
Add Bookmark
Description: In this lesson, one of a multipart 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. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
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. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
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.

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
