Pythagorean Theorem
Pupils explore how the Pythagorean Theorem works and how to apply it.
Curated OER
Pythagorean Theorem
Students are introduced to the Pythagorean theorem. They use three different activities that give students the opportuntiy to observe triangles, and use the Pythagorean theorem and practice different ways of determining areas of...

The Quadratic Formula
Students solve quadratic function by completing the square. In this algebra lesson plan, students use the quadratic formula to factor quadratics and find the roots. They graph the parabola and identify its properties.
Curated OER
Transversal and Angles
Tenth graders identify angles formed by parallel lines and a transversal. Using meter sticks and bolts, they perform hands-on activities to demonstrate the properties of parallel lines and congruent angles. They color code diagrams to...

From Where to Where?
Learners find locations based upon their latitude and longitude coordinates. In this latitude and longitude lesson, students locate points on a grid and learn how to use an astrolabe.
Curated OER
Tessellations
Students form repeating patterns using tessellations. For this tessellations lesson, students identify shapes and illustrate three types of transformations. A website is included with the lesson which provides extension activities and...
Curated OER
Sorting
Students sort a variety of manipulatives and use a software program that provides more sorting practice.
Curated OER
Finding The Circumference Given The Radius
Students develop an understanding of pi and the relationship between the diameter, radius and circumference. After a lecture/demo, students use construction paper and a compass to solve problems using diameter, radius and circumference.
Curated OER
African Ceremonial Masks
Fourth graders examine and discuss the purposes and traditions of African ceremonial masks. They design and create African ceremonial masks using various materials.
Curated OER
Surface Area and Volume
Students are introduced to the notion of surface area and volume. Students review surface area and volume by finding the area of a two-dimensional shape. They practice using the computer to create different surface area shapes.

Math: Gears and Wheels
Twelfth graders solve problems involving linear and angular speed. Using information about a compact disc, they solve the problem using multiple rates and conversion factors. Students also solve additional problems involving bicycle...
Curated OER
Ship Shape
Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.
Curated OER
Fractals
Students explore the concept of fractals. In this fractal lesson plan, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...

Creating Polygons
Learners describe, make and compare polygons. In this creating polygons instructional activity, students identify properties of quadrilaterals and describe common features of two dimensional shapes.
Curated OER
Follow The Falling Meteorite
Students investigate the supposed traveling path of a meteorite. They use sound in order to triangulate the path. The results of the experiment are written on a map to display the path of the meteorite. The culminating activity is when...
Curated OER
Justifying Mathematical Conjectures
Sixth graders, in groups, explain why they think something. This requires students to listen to and respond to each other. In this particular lesson, 6th graders explain to their classmates when one can or cannot construct a specific...
Curated OER
Shape It
Fourth graders use math software and geoboard paper to design basic shapes. They write individual definitions for the geometric shapes based on what they see in the shapes. They apply their background knowledge of the shape as they write...
