ExplorA-Pond:3rd Grade Shapes & Fractions
Students, using a map, drawing or aerial view of a pond, represent the shape of the pond using simple geometric shapes or fractions of those shapes. They identify the numerator and denominator in each fraction created.

Geometric Pictures of One Half
A learning task that involves creative ways of thinking permits children to use paper models as a way to visualize the fraction one-half. Learners can fold or cut their models in such a way that the unshaded regions, and shaded...

Egyptian Numeration Pyramid
Fourth graders, using paper, construct a 3-D pyramid, decorating it with Egyptian numbers.
Curated OER
ndirect Measurement Technique: Using Trigonometric Ratios
Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...
Curated OER
Listen to a Shape
First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.
Curated OER
Geometric Figures
Students compare, classify and calculate the area of geometric figures such as rectangles, squares, circles and triangles.
Curated OER
Bill's Badge
Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.
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...
Curated OER
Angles, Parallel Lines, and Polygons
Young scholars examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate...
Curated OER
Pyramid Play
Students investigate the concept of the Food Pyramid. They use a game as a tool of discovery in order to classify different types of food in the pyramid. Upon completion of the game the students construct their own models of it.
Curated OER
Measuring with Mathematics
Eighth graders discover how the change in the dimensions of a shape cause a change in the overall area of the shape, but the perimeter stay the same. They, in groups, go out to the playground and construct large areas using stakes and rope.
Curated OER
Kindergarten Shape Books
Students, in groups, identify examples of shapes around the school site. They take digital pictures of these shapes and use them to construct a class book.
Curated OER
Pattern Block Activities
Students practice various math skills by using manipulative activities. For this math manipulative lesson, students sort shapes, build hexagons, and build shapes using manipulatives. These activities would be great for parent ed or...

Koch Snowflake
Students investigate Koch's Snowflake. In this geometry lesson, students identify the properties of creating Koch's snowflake. They solve problems dealing with fractals and patterns.
Curated OER
Fractals: Koch Snowflake
Students investigate the properties of Koch's snowflake. In this geometry lesson plan, students investigate fractals and patterns. They create Koch's snowflake using Cabri software.
Curated OER
The Trappings of Trapezoids
Students define trapezoids and their shapes. In this geometry lesson, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.

Whatcha Gunna Do When the Hulkster's Measuring Too??
Learners measure using tools they have made. In this algebra lesson, students measure the height and distance using non-traditional measuring methods. They apply their findings to algebra and trigonometry properties of measurements.
Curated OER
Tessellations
Students create tessellations. In this geometry lesson plan, students use polygons to create different patterns by rotation. They identify the reasons for polygons to create the type of tessellation it does.
Curated OER
Using Geometric Shapes To Make Patterns
Sixth graders explore the use of shapes to create geometric patterns. they start with a simple example of dividing shapes in half to create two new ones. This can be extended to creating intricate patterns.
Curated OER
Interior and Exterior Angles of Polygons
Students identify interior and exterior angles of polygons. In this geometry lesson, students add interior and exterior angles of polygons. They use angle theorems to solve the problems.
