In this system of axes worksheet, 10th graders solve and complete 1 word problem. First, they determine the figure shown in the illustration and set-up an expression. Then, students solve to find the shaded region of the diagram.

Use a triangle area formula that works when the height is unknown. The eighth installment in a 16-part series on trigonometry revisits the trigonometric triangle area formula that previously was shown to work with the acute triangles....

Young scholars examine transformations. In this math lesson, students view and describe flips, slides, and turns. Young scholars practice making transformations with shapes.

Twelfth graders build a model of the following figures with the base from column I and the cross-section from column II. Draw the base with labeled axes on the graph paper and construct the figure on top of the base with the play dough...

Students explore the concept of Mandelbrot sets and Julia sets. In this Mandelbrot and Julia set lesson, students use a function integrator applet to investigate two-variable function iterations. Students use Julia set and Mandelbrot set...

Second graders identify different polygons and their attributes. In this geometry lesson, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and then find their...

Students create a scrapbook. In this geometry lesson, students use digital cameras to take pictures of geometrical concepts. Students use the pictures to create a "Geotown" scrapbook.

Fifth graders create math word problems. In this geometry lesson plan, 5th graders define perimeter and discover how to find the perimeter of a rectangle, a square and a regular polygon. Students write word problems on finding the...

Sixth grade students: 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 explore how geometry is used on the composition of artworks by artists from different cultures. This lesson is equally suited for a Math or Art classroom at the late-elementary or early-middle school level.

Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Fourth graders find the volume of solids. In groups, 4th graders use spinners to determine the dimensions of solids. They construct the shapes, creating a model of the figure Students count the cubes in the model to determine the...

Students create posters about geometric shapes in order to demonstrate their understanding of the different shapes. Students look for pictures in magazines to represent two-dimensional shapes, paste them on a poster, label the shape,...

Fourth graders use computer drawing tools to create a house of geometric shapes.

Learners perform transformations and translation on a coordinate plane. In this geometry instructional activity, students move shapes around on a graph identifying translation, image, and transformation. This instructional activity has...

Students investigate the Pythagorean Theorem.  In this seventh through twelfth grade geometery lesson plan, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side of a right...

Students draw on graph paper. In this geometry lesson, students review types of triangles and quadrilaterals. Students investigate geometric transformations, including translation, rotation and reflection. Students practice each...

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.

Students perform translations on different polygons. In this geometry activity, students create figures that will be used as an assessment to represent transformation. They perform hands on creation and relate it to the real world.

Students explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.

Learners explore the concept of geometric shapes. For this geometric shape lesson, students play bingo to review geometric shapes. Learners identify the shape being described by the teacher and put a marker on their bingo card.

Tenth graders investigate the volume of a cylinder.  In this geometry lesson, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions.  The lesson progresses to the use of the formula to find...

Students investigate image and pre-image. In this geometry lesson plan, students identify the reflection and rotation of different shape on a coordinate plane. They identify similarities and differences of image and pre-image of a...
