Students follow directions in the ABC of Symmetry to make a butterfly which shows a line of symmetry.

Young scholars investigate and solve Pythagorean triples. In this geometry instructional activity, students find the missing sides and angles of a right triangle. They graph right triangles and move the sides around to create different...

Students listen to a read aloud of The Quiltmaker's Gift by Jeff Brumbeau finding examples of symmetry in the illustrations in the book.

Students examine various closed and open figures. They decide which letters have closed figures. Then they receive a pre-made name card and decorate every closed figure in their name.

Third graders are given square tiles and participate in a demonstration on how to arrange them. Using the tiles, they work with a partner to discover how many two-dimensional tetrominoes they can create. To end the lesson, they must...

Students identify the two-dimensional geometric shapes Lowrey utilized in the painting Untitled. Students compare the two-dimensional shapes in terms of equivalent fractions, congruency, symmetry and asymmetry. Students create their own...

Second graders manipulate triangles to discover the concepts of slides, flips and turns of a geometric shape.

Students take a sample of fish and try to determine how many fish are in the sea.  In this scientific sampling lesson, students explore the way scientists measure large areas of samples. Students record the distribution in a quadrant.

Sixth grade pupils: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.

Students review geometry unit content through a vocabulary/word game. They demonstrate understanding using geoboards to answer questions. They work in groups and it's a race to the correct answer.

Fifth graders explore polygons. In this math lesson, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.

Students study pyramids. In this prisms lesson, students explore the attributes of pyramids. Students will explore the lateral surface area of pyramids and be able to distinguish pyramids from other space shapes.

Learners observe and solve examples of betweenness, ruler postulate, and segment addition postulate. They complete the Finding the Measure of Segments worksheet using the distance formula.

Fourth graders explore the definition and properties of parallel lines. This high level lesson has students calculate the slope of the two parallel lines, and draw the lines on a Caretsian coordinate system.

Students create reflections over two lines. In this reflections worksheet, students compare and contrast reflections over parallel and intersecting lines. They dilate figures and investigate the effect of the dilation using measurement...

Students use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson plan.

Learners explore geometry by completing a math worksheet in class. In this shape identification lesson, students identify the characteristics associated with 15 solid geometric shapes. Learners identify patterns between vertices, edges...

Pupils create a new playground design to present to elementary students during Playground safety week. They review basic geometry to use in observing and recording the equipment on a local playground. They research playground safety...

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

Fourth graders create mandalas. In this mandala instructional activity, 4th graders look at these polygons in nature and man-made forms. They create their own by using tangrams.

Learners recognize and identify shapes in their environment. They investigate why objects can be composed of several different shapes. They follow a pattern to recreate designs using various shapes.

In this online interactive history activity, students respond to 10 short answer and essay questions about the achievements of Johannes Kepler. Students may check some of their answers on the interactive activity.

What did you do over your summer vacation. Young wage earners must compare summer job options, and determine when each job earn the same amount and what that amount be. This be done by creating, graphing, and solving systems of...

Students investigate triangles. In this shapes geometry lesson, students define and state the attributes for equilateral, scalene, and isosceles triangles. Students locate the prefix "tri" in a variety of words and make connections with...
