Curated OER
Polygon Sum Conjecture
Students calculate the sum of the angles of a polygon. In this geometry lesson plan, students use the interior angle formula of polygon based on the number of sides of the polygon. They identify the missing angle using algebra.
Curated OER
Identifying Lines of Symmetry
Students calculate the lines of symmetry using polygons. In this geometry lesson, students graph, compare and estimate using collected data. They identify different attributes to the polygons based on their sides.

Geo Jammin' - Day 1, Lesson 1: Gee Quiz!
Second graders are introduced to geometry by a teacher made puppet called Geo George.
Curated OER
Function Tables
Learners practice representing problems found in the real world in terms that can be translated into mathematical expressions. The situations are represented in tables and graphs by students.
Curated OER
M & M Fractions
Students receive 10 M & M's to study about fractions. As a class, they divide the ten M & M's into a half. They then take away two and use the eight M & M's to study about fourths. They also use nine to study about thirds.
Curated OER
Analyzing Body Angles
Students investigate angles of polygons. In this geometry lesson, students identify the relationship between angles and the number of sides in a polygon. They differentiate between sumilarity anf congruence in angles and sides.
Curated OER
Studying Special Segments in Triangles
Students investigate special segments in triangles. In this geometry lesson, students graph, compare, estimate and predict findings based on their data. They differentiate between similarity and congruence of triangles.
Curated OER
Stained Glass Critter
Students investigate the the origination of stained glass in the 12th century cathedrals.
They practice writing their names in cursive symmetrically. Students also practice how to make a stained glass image.

Keith Haring and Graffiti
Students appreciate the art of the artist Keith Haring. They design and implement Keith Haring-like images for a wall mural and explain and experience a project containing many different compenents and processes from beginning to end.
Curated OER
Lines of Symmetry
Fifth graders explore the concept of symmetry using lines drawn through different shapes. The worksheet that is included in the lesson should be used to chart the lines of symmetry for the different shapes drawn.
Curated OER
What Makes A Face A Face?
Students discuss what enables us to read a face: features, expressions, standards of beauty, age and gender. They discuss what enables us to read motion: repetition, sequence, changes in form and scene.

The Dragon Curve Fractal
Students identify the properties of a dragon curve. In this geometry lesson, students identify sequences and patterns as they solve fractals. They investigate patterns found in nature.
Curated OER
Are you in Golden Shape
Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.
Curated OER
Making Parallel Lines
Students differentiate between parallel and perpendicular lines. In this geometry lesson, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.

More No-Three-In-A-Line
Fourth graders read Mary's problem and make sure that they examine it.
After some discussion, let the class work on the problem in their groups.
They then take turns in putting a picture of their arrangement on the board.

No-Three-In-A-Line Again
Young scholars interpret information and results in context while using words and symbols to generalize patterns. They use symmetry and angle properties of polygons to solve practical problems and identifying invariant properties under...
Curated OER
No-More-In-A-Line
Young scholars and teacher discuss square windows and their symmetry. Students work on the problem given and discuss any difficult ideas. They work in groups to use a systematic approach to get all possible answers.
Curated OER
Angle Pairs
Students practice identifying right, vertical, and adjacent angles using a Smartboard. They then determine measurements of all of the angles when only one measurement is given.
Curated OER
Angles and Parallel Lines
Sixth graders draw parallel and intersecting lines to observe and examine the characteristics of alternate interior angles, vertical angles, corresponding angles, and supplementary angles. Through observation, they discover the...

Wing Shapes and Areas
Students, after reading the explanation given below, use FoilSim to determine the weight of the aircraft that can be lifted by a pair of wings of each type. They also design a unique platform of a wing to lift a plane weighing 11500 pounds.
Curated OER
Characteristics of Lift and Wing Area
Learners use FoilSim to complete the activity and investigate the factors that affect lift and how wing area and lift are related.
Curated OER
Fitness
Fourth graders determine how to design regular and semi-regular tessellations of the plane. They develop the ability to demonstrate why a tessellation covers the plane in this series of lessons.
