Lesson Plans: Learning Geometry: A series of on-line videos for teachers related to various geometry concepts. Learner.org - What is Geometry? In this lesson, students will learn to solve visual geometric problems, use mathematical language and construct basic objects. Learner.org - Triangles and Quadrilaterals Students will classify, determine a rule for creating triangles and construct a triangle and quadrilateral. Learner.org - Polygons Students will broaden thinking about polygons, classify polygons and begin to understand mathematical definitions. Learner.org - Parallel Lines and Circles Students will be introduced to Geometer's Sketchpad, study parallel lines, circles and use technology. Learner.org - Dissection and Proof In this lesson, students will learn to dissect geometric figures into pieces you can rearrange to form different geometric figures. Use geometric language to describe your reasoning, justification, and solutions to problems and prove the midline theorem. Learner.org - The Pythagorean Theorem Students will learn how to examine proofs, apply the Pythagorean theorem and use the distance formula Learner.org - Symmetry In this lesson, students will learn about and explore symmetry. Learner.org - Similarity Students will explore geometric similarity, study similar triangles and explore basic ideas of trigonometry. Learner.org - Solids Students learn various aspects of solid geometry, explore platonic solids and examine 2-D properties such as nets and cross sections. Learner.org - Classroom Case Studies In this session, we will examine how geometry as a problem-solving process might look when applied to situations in your own classroom. This session is customized for three grade levels. Math Forum - 3-D Visualization Activity: Students will draw a 3-d object and use appropriate vocabulary. An Introduction To Quadrilaterals: This lesson is designed to introduce students to quadrilaterals. Included in this lesson are discussions of parallelograms, rectangles, and trapezoids. Plane Geometry: Students will demonstrate a sense of spatial awareness and familiarity with two dimensional shapes and recognize relationships between geometry and the environment. Tantalizing Tessellations: These activities ask students to respond to the concepts of tessellations. Tessellation Tutorial: Step by step directions for making tessellations using a computer's paint program. Equilateral Triangles and Beyond: Steps for constructing an equilateral triangle. Graphic Design: Using Symmetry to Create Corporate Logos Symmetry: In this session, students will explore geometric versions of symmetry by creating designs and examining their properties. Fraction Facts: Introduces students to fractions and explores basic mathematical operations with fractions, comparing fractions, and converting fractions into decimals or percents. There are several computer based games embedded in these lessons. Skill in Arithmetic - Proper Factions, Mixed Numbers, Improper Fractions What is a common fraction? What is a proper fraction? How are the proper fractions named? Skill in Arithmetic - Equivalent Fractions What are equivalent fractions? How can we know when fractions are equivalent? Skill in Arithmetic - Compare Fractions How can we compare fractions with the same numerator? How can we compare fractions with the same denominator? Beat the Calculator: Math challenge demonstrating concepts that allow students to rapidly compute fractions mentally.

Resources: Equivalent Fraction Matching Game: Fast paced, great for students working in pairs. Dan Brown: Ambigrams An ambigram is a word written in such a way that it is legible both right side-up and upside-down. Ambigrams are an ancient art form and play heavily into the mysteries of Dan Brown's books. How Would You Hang This Sign? This site gives an example of two words that look the same when they are flipped together. It is a great launch for a math lesson on symmetry. The Four Types of Symmetry in the Plane: An explanation with diagrams. Spike's Game Zone: Colorful interactive activities and games that demonstrate fraction concepts. AAA Math - Subtracting Mixed Numbers: Short self paced lesson explaining how to subtract fractions with a self check game following the lesson. Quia: Subtracting w/ Renaming Mixed Numbers: Students have their choice of matching, flashcards, and concentration games focusing on subtracting mixed numbers where renaming is necessary. All three of these games are in either Java and Non-Java versions. Geometric Figures Fast Facts: Definitions and formulas for circles rectangles, and triangles. Figures and Polygons: A list of definitions and explanations about various geometric figures and polygons. Geometry Problem of the Week Polyhedra in the Classroom: This is a list of activities designed to allow students an opportunity to work on specific mathematical ideas through the use of technology. Polyhedra Acrtivities Classroom Polyhedra Activities: Ideas and plans for many polyhedra models. Geometry K-12: A list of helpful resources and activities. Mathematics Museum: This is a mathematics website for Japanese high school students. It has wonderful geometry animations.
