Subject: Mathematics (4) Title: Lay It on the Line
Description: This lesson allows students to explore their surroundings to locate and prove the presence of perpendicular lines. Students will use the corner of a ruler as a tester to determine right angles contained in classroom items. It can be included in a unit on geometry and measurement.
This is a College and CareerReady Standards showcase lesson plan.
Subject: Mathematics (4) Title: Pizza Problems: An Angle Investigation
Description: This investigative lesson allows students to identify angle measurements as part of a larger angle. Students will deconstruct 180 degree angles into equal parts.
This is a College and CareerReady Standards showcase lesson plan.
Subject: Mathematics (4) Title: Talking in Circles
Description: The students will identify parts of the circle including center, radius, diameter, chord, and arc.
This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.
Subject: English Language Arts (3), or Mathematics (3  5), or Technology Education (3  5) Title: Weight vs. Capacity
Description: This lesson will introduce students to measuring weight, mass, volume, and capacity using metric and cutomary units.
This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.
Subject: Mathematics (3  5), or Technology Education (3  5) Title: $100 Picture
Description: This is a lesson where collaborative learning groups are used to explore perimeter and area of an irregular figure using pattern blocks. This lesson should be used after students have already had some experience with finding the perimeter and area of a figure.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMSU Project.
Subject: Mathematics (3  5) Title: The Class Quilt
Description: Students will design a 12 inch quilt square consisting of geometrical shapes.They must use their knowledge of fractions and polygons in order to create an exact 12" by 12" square.Students will use knowledge of area of a figure in order to create a quilt using their squares.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMSU Project.

Subject: Mathematics Title: Concentration
Add Bookmark
Description: This student interactive from Illuminations allows students to play the classic game of Concentration by themselves or against a friend. The interactive can be used to review numbers, shapes, multiplication facts, fractions, decimals, and percents. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2,3,4,5
Subject: Mathematics Title: Building with Triangles
Add Bookmark
Description: This unit of four lessons, from Illuminations, focuses on triangles and their properties. Each investigation begins with an openended question that challenges students to become actively involved in mathematical experiments, ideas, discussions, manipulative materials, tools, and techniques.

Subject: Mathematics  Applied Mathematics  Social Studies  Geography Title: Geography of Pizza
Add Bookmark
Description: In this lesson, from Xpeditions, students analyze Earth's surface according to the spatial elements of points, lines, and areas, and use a simple map to identify features in terms of spatial elements. This lesson uses a pizza restaurant to introduce these components to students, e.g., the location of a restaurant (point), roads and sidewalks (lines), and the city blocks or the region served by a restaurant (area).

Subject: Mathematics Title: Clothing Sizes
Add Bookmark
Description: This reproducible worksheet, from an Illuminations lesson, prompts students to analyze measurements of their body, specifically as they relate to clothing sizes. 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. Users can read the Illuminations Editorial Board's review of each Web site, or choose to link directly to the sites. Thinkfinity Partner: Illuminations Grade Span: K,1,2,3,4,5,6,7,8,9,10,11,12
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: Arts,Mathematics Title: Constructing a ThreeDimensional Model
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students build a three dimensional model of a clubhouse from two dimensional blueprints designed in an earlier lesson. In addition, they solve problems related to constructing and decorating their clubhouse. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: Rectangles and Parallelograms
Add Bookmark
Description: In this lesson, from Illuminations, students use dynamic software to examine the properties of rectangles and parallelograms and then identify what distinguishes a rectangle from a more general parallelogram. Using spatial relationships, they examine the properties of two and threedimensional shapes. The lesson links to a virtual manipulative that allows students to compare rectangles and parallelograms.
