Learners investigate the symmetries of a convex quadrilateral in a collaborative activity. Rigid motion and complements are explored as learners analyze different cases of reflections across a line.

An AP calculus lesson begins with an activity to determine the volume of a solid using a cross-section. Next, learners review the ways to find the area between two curves , as well how to find the volume of a solid created...

Discover the relationship between tangent lines and the tangent function. Class members develop the idea of the tangent function using the unit circle. They create tables of values and explore the domain, range, and end behavior of...

Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...

Learners investigate the symmetry that is found in nature. They view shapes and patterns in nature while looking at images. Students look for tessellations while obtaining photographs with a digital camera. The information is used for...

Students identify the transformation and rotation of polygons. In this geometry lesson, students use picture to perform rotation, reflection and transformation. They identify the coordinate points of the new transformation.

Second graders and teachers identify geometric vocabulary word by searching a geometry website. They create a Quilt Word Wall using the geometry words.

Learners explore the concept of transformations. In this transformations instructional activity, students use Geometer's Sketchpad to construct cyclic and dihedral figures. Learners study reflection and rotation symmetry. Students...

Students create different shapes on grid paper.  In this two-dimensional geometry lesson, students take turns outlining a shape made of six squares on the graph paper.  They identify all shapes they see once everyone has had a...

In this geometry skills worksheet, students graph a triangle using the provided information and then respond to 3 short answer questions regarding it.

In this identifying transformations learning exercise, 3rd graders look at three figures and choose reflected, rotated or translated to indicate how it has been transformed.

Fifth graders explore geometry by exploring Pi. In this circle measurement lesson plan, 5th graders identify the relationship between the radius, diameter and circumference of a circle and how Pi is the key to unlocking any circular...

Students listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.

In this math worksheet, learners look for the words that are related to the math words used in the practice of geometry. They also practice spelling.

Students 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 examples...

Students explore the concept of congruent triangles.  In this congruent triangles instructional activity, students use Cabri Jr. to construct two congruent triangles using circles.  Students determine if the two triangles are...

In this math worksheet, students use protractors to measure each of a set of angles. This is a worksheet generator, the teacher controls the minimum and maximum angles students are presented with as well as whether or not to rotate...

You know the Inscribed Angle Theorem and you know about tangent lines; now let's consider them together! Learners first explore angle measures when one of the rays of the angle is a tangent to a circle. They then apply their...

So a cylinder does not have to look like a can? By expanding upon the precise definition of a rectangular prism, the lesson develops the definition of a general cylinder. Scholars continue on to develop a graphical organizer...

An interactive comprised of five questions challenges young scholars to complete a simple pattern. After examining a train with colored carts, learners arrange a green, blue, and yellow block into their corresponding space. Questions are...

A six-question interactive tasks mathematicians to solve addition and subtraction problems using front-end estimation. Question types consist of multiple-choice and true or false. A set of wooden beams that can be measured using moveable...

Here is a study guide on transformations that includes reflections, translations, dilations, and rotations. It also has definitions, helpful diagrams, and several examples involving transformations on the coordinate plane. The lesson...

In this transformations worksheet, pupils draw the transformations of the triangles and parallelograms in graphs. They complete four drawings.

Bring about the change you want to see in the world  or at least in your lesson plans. Young mathematicians learn about translation and reflections by applying them to polygons on the coordinate plane. Results provide data to...
