An outstanding lesson on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle...

Create the ultimate miniature golf course. The 93-page model curriculum unit from the Massachusetts Department of Elementary and Secondary Education contains nine lessons on understanding similarity in terms of both Euclidean geometry...

This is an intriguing problem that brings together real-world data, technology, and mathematical problem solving. If visibility wasn't an issue, could you see from the highest point in the lower 48 states, Mt. Whitney, to the lowest...

Students use the inequality theorem to solve triangles and their properties. In this geometry lesson, students are given spaghetti of different lengths and asked to create triangles. They conclude the necessary length needed to make a...

Fifth graders identify lines of symmetry., similar and congruent shapes. They use construction paper to create their own symmetrical shapes. Students create stained glass frames containing symmetrical, congruent and similar shapes.

These four lesson plans build algebra skills for working with numbers in exponential form and for examining triangles. Be aware that in the text, scientific notation is referred to as index notation and the laws of exponents as the laws...

Students explore the concept of right triangles. In this right triangle instructional activity, students construct a scale model of a tourist attraction similar to Fort Jefferson. Students research aerial photos of Fort Jefferson, then...

Middle schoolers construct a three-dimensional model of a city using both similar and congruent figures and geometric transformations. City must have at least ten buildings with each building labeled and may be constructed out of paper...

Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade...

Students make dog collages using triangles and rectangles. In this collage lesson, students use cut-out triangles and rectangles to make a dog collage after looking examples of Keith Haring's work and listening to Emma Dodd's, Dog's...

Third graders examine the artwork of Faith Ringgold. They create their own quilt pattern on fabric and piece them together to create a class quilt. They compare their similarities with one another.

Learners create sets of similar triangles which, when fixed together with a piece of Scotch tape, form a spiral-like, segmented shape, slightly similar to the cross section of the shell of a nautilus.

Students investigate the physical properties of fire by creating storyboards.  In this elements lesson, students view a video clip of forest fires and identify the cause.  Students create large storyboards defining the three...

Pupils explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

Students explore two-dimensional and solid shapes. In this shapes and patterns geometry lesson plan, students work with a partner to create identifiable objects using tangrams. Students describe the attributes of their shape and their...

Ninth graders explore a variety of geometry and science concept while making an origami frog. The fold paper into the shape of a frog and conduct measurement activities including frog leaps.

Students study a variety of geometric shapes by taking pictures of items representing the shapes with a digital camera. They identify the shapes by using software to paint on the image.

Learners identify points on the coordinate plane using ordered pairs and also plot the ordered pairs on the coordinate plane. They also use properties of shapes to identify polygons such as triangles and quadrilaterals (square,...

Students examine and identify the similarities and differences of two-dimensional shapes. They play an I-Spy shape game, participate in a classroom Shape Search, and create illustrations of shapes for a shape collage.

Second graders compare and contrast historical American cultures.  In this American history lesson plan, 2nd graders participate in reading, writing, oral, and hands on activities. Students discuss the similarities and differences...

Learners discover different geometric shapes such as triangle, square, rectangle, and octagon. Students incorporate the use of technology by taking pictures of shapes around their school using a digital camera.

Students and parents participate in a variety of activities designed to help them explore the similarities and differences of people. They design and wear masks, sort attribute blocks, read stories, discuss the rights and...

Students study about our dependence on the earth's resources for materials. They practice their knowledge of geometric shapes by recognizing them in the context of the story.
