Students define important vocabulary words using a dictionary. In this geometry instructional activity, students identify and use properties of triangles to solve problems. They identify the median. altitude and angles as well as...

Sixth graders identify and use area formulas for finding the area of geometric shapes.

Students identify different types of special right triangles. In this geometry lesson, students differentiate between right triangles and isosceles triangles. they construct the triangles using geometry software and make conjectures...

Pupils solve problems using fractals. In this geometry lesson, students identify properties of fractals. They find patterns in their surroundings and relate it to the real world and math.

Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson plan, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

Students study West Virginia quilts. In this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.

Young scholars complete a variety of activities surrounding minerals, crystals, and mineralogy. They locate common minerals on a world map, complete a lab in which they identify the chemical and physical properties of various minerals,...

Students observe a selection of shapes. They identify which shapes will tessellate and justify their answer. Students apply the symmetry and angle properties of polygons to create tessellations.

Students tackle the problem of how to divide a triangular piece of land fairly among four people. They decide whether their method of fair division always works or if it only works in special cases.

Lead your high school class on a journey through the world of symmetry and reflections as you discuss geometric principles. Pupils differentiate between reflections and rotations, explore rotational symmetry, and investigate how to...

Elementary graders discover the concept of fractional pieces of a whole. They investigate the meanings of fractions in everyday life and why they are used. Pupils divide brownies amongst each other to demonstrate the use of fractions...

Get a handle on equivalent fractions through the use of manipulatives. Using area models, sets, and length manipulatives like fraction strips and Cuisenaire rods, the class will gain a deeper understanding of equivalent fractions....

Young scholars respond to Tony Smith's sculpture as art and brainstorm about math concepts inherent in his work. They create a sculpture with polyhedra nets, calculate the cost of covering sculpture in gold, and write an exhibit label...

Middle schoolers investigate the concept of tessellations and how they are formed using angles. They categorize how different patterns do and not tessellate and separate them into two different places for assessment. The teacher draws...

Students, as a final project, draw a picture of their ideal neighborhood on a sunny day. In addition to the sun, their drawings include homes, trees, streets, and selected objects. Each object in their drawing has a written description...

Third graders represent fractions as part of a whole. In this fractions lesson, 3rd graders use manipulatives to show how a fraction is a part of a whole. This lesson includes individual practice and an assessment instead of direct...

Third graders use fractions to describe part of a set. In this fractions instructional activity, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This instructional...

Incorporating concepts in algebra, number sense, patterning, data collection, and geometry, this lesson engages students in various hands-on activities to explore the relationship between regular polygons and the number of diagonals...

An integrated geometry lesson on spatial sense in which students identify and use different shapes to create a tessellation. "Through a variety of modalities such as writing, music, art, poetry, and literature, students are introduced to...
