ALEX Lesson Plans
Subject: Mathematics (K  2), or Technology Education (K  2) Title: Stop, Look, and Find Shapes in Our School and Community!
Description: This is a projectbased lesson that provides many handson opportunities for students to learn about shapes in their environment. Students are challenged to find shapes in our world using everyday technology. Students review the characteristics of basic shapes such as squares, triangles, circles, etc. They will then learn how to use digital cameras to capture shapes in the environment and will create a digital book of their photos.
Subject: Character Education (K  12), or English Language Arts (1), or Mathematics (K  1), or Technology Education (K  2) Title: "Shape Up or Ship Out"
Description: In this activity, students will identify shapes that architects use to build houses. Students will then explore these shapes by building a model "dream" home.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMSU Project.
Subject: Mathematics (K), or Technology Education (K  2) Title: Geometric Shapes
Description: During this lesson, students will explore shapes and become aware of shapes all around them. They will search for shapes in a variety of places and explore shapes on the Internet.
Subject: Mathematics (K  2), or Technology Education (K  2) Title: Congruent Figures
Description: This lesson is an introduction to a unit about congruent shapes. Students will begin by listening to a book about shapes. They will then complete several handson activities, including sorting shapes, using their bodies to form congruent shapes, and using activities on the Internet to practice forming congruent shapes.
Subject: Mathematics (K  2), or Technology Education (K  2) Title: Shapes in the Classroom
Description: This lesson will teach students to identify solid figures found in the classroom and in magazines. Students will also learn more about solid figures using the Internet.
Subject: Arts Education (K), or Mathematics (K  2), or Technology Education (K  2) Title: Tantalizing Tangrams
Description: This is an introductory lesson using tangrams. Students will observe the seven geometric shapes that make up the tangram in a variety of ways that exhibit spatial relationships. They will have handson experiences using these tangrams to create new shapes. Finally, they will try to make the seven shapes form a square.

Description: Describing figures and visualizing what they look like when they are transformed through rotations or flips or are put together or taken apart in different ways are important aspects of geometry in the lower grades. This twopart tangram example from Illuminations demonstrates the potential for highquality experiences provided by computer 'shape' environments for students as they learn concepts described in the Geometry Standard. Problemsolving tasks that involve physical manipulatives as well as virtual manipulatives afford many students an entry into mathematics that they might not otherwise experience.

Description: In this fourlesson unit from Illuminations, students develop their understanding and use of patterns as they analyze relationships and make predictions. Students use interactive math applets to learn about repeating and growing patterns. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics,Social Studies Title: Going Places
Add Bookmark
Description: This unit of seven lessons, from Illuminations, engages students in activities that use measurement and geometry. Students investigate various areas and objects they see each day to apply ideas of navigating in space and understanding the relationships among these various elements.

Subject: Mathematics Title: Ladybug Mazes
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students plan a series of moves that navigate a ladybug through a maze. Their plans turn the ladybug at the appropriate corners and keep it on a path without crossing the walls. This activity helps students gain experience in estimating length and angle measures.

Description: Create customized activity sheets for your classroom! Nets of 3D shapes, tessellations, coordinate graphs, and more  all based on your input. Thinkfinity Partner: Illuminations Grade Span: K,1,2,3,4,5,6,7,8,9,10,11,12
Subject: Mathematics Title: Investigating the Concept of Triangle and the Properties of Polygons: Making Triangles
Add Bookmark
Description: This twopart example from Illuminations describes activities using interactive geoboards to help students identify simple geometric shapes, describe their properties, and develop spatial sense. This first part, Making Triangles, focuses attention on the concept of triangle, helping students understand the mathematical meaning of a triangle and the idea of congruence, or sameness, in geometry. In the next part, Creating Polygons, students make and compare a variety of polygons, describing the salient properties of the shapes they create. 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. Thinkfinity Partner: Illuminations Grade Span: K,1,2
Subject: Mathematics Title: Multiple Patterns
