Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

Help your middle and high schoolers explore geometric terminology. In this geometry lesson, learners use the entire year to create an ABC Geometry book. Learners use a list of terms learned in class to create a page for each letter....

A geometry game that resembles Battleship is the foundation for hide and seek where "hiders" draw shapes on coordinate planes and "seekers" must guess the shape and its location based on questions and clues. Reproducible, paper-sized...

Middle schoolers complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a...

Develop young mathematicians' knowledge of two- and three-dimensional shapes with this geometry workbook. From learning about the classifications of different shapes and figures to calculating their area, perimeter, and volume, this...

Add some visual support to your elementary geometry lessons with this set of printable shape cards. From triangles and squares to octagons and nanogons, this simple resource can be used in countless ways to develop children's knowledge...

Kindergartners identify geometric shapes by planting a fall garden. They start their seeds in containers that have different shapes, and keep track of their plants based on those shapes. This brilliantly designed and incredibly thorough...

Tenth graders investigate the early history of geometry. In this geometry lesson, 10th graders investigate translations, rotations, and reflections. They also solve problems with line of symmetry and rotational symmetry while reviewing...

Elementary schoolers utilize a pattern worksheet embedded in this plan to work on a deeper understanding of geometric concepts like symmetry and congruency. Since geometry is such a visual form of mathematics, this instructional activity...

Learners review the parts of a circle, calculate the circumference and area of a circle, and create student-made tests on the geometry of circles using educational software.

Third graders describe 2D and 3D shapes. In this geometry lesson, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they have in...

Students complete worksheets involving rotational symmetry. In this geometry instructional activity, students complete worksheets to identify rotational symmetry and rotations. They compare and contrast rotated figures. Students examine...

Students construct two-column proofs. In this geometry lesson, students use deductive reasoning and geometric properties to justify given geometric statements. Students compare and contrast proofs.

Students are introduced to the basics of Geometry. Using cutout shapes, they identify whether they are polygons by using the properties of polygons. They practice drawing shapes they are going to be using on an everyday basis and...

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

Young scholars identify and name basic shapes and points. In this elementary geometry lesson, students use printable cut outs to name circles, triangles, and squares before playing a game with them. They play a game of "Pin the Tail on...

First graders review the placement of positional words and shapes. In groups, they travel between eight centers throughout the classroom in which they participate in various activities. They focus on concepts that are related to Geometry.

Students explore the characteristics of geometric shapes. For this geometric shapes lesson, students use tiles to draw pentominoes. Students participate in various learning center activities focused on configuring pentominoes.

Students calculate the area of different polygons. In this geometry lesson, students find the area of complex polygons. They solve word problems using rates and distances.

Tenth graders investigate the history of Pi and how it relates to circles. In this geometry instructional activity, 10th graders measure the circumference of a circle and the diameter of a circle. They relate these measurements to the...

Students play a "Battleship" type of game to practice graphing on a coordinate plane. In this coordinate graphing lesson, students select a point on their grid to place their "battleship." It the opposing team misses the ship, the...

Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes. This...

High schoolers explore the concept of quadrilaterals. In this quadrilaterals lesson plan, students use the slope formula, midpoint formula, and distance formula to justify that a given quadrilateral is a parallelogram.

Students develop math vocabulary by chapter. In this math vocabulary instructional activity, students develop a notebook of math words and their definitions for each chapter throughout the year. They use these words to further...
