Students investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

In this math and science worksheet, students read about the process of photosynthesis and plant growth. They determine how a plant's ability to create food is dependent on the surface area of its leaves using geometric calculations. They...

Second graders utilize manipulatives (pentominoes) to demonstrate knowledge of: lines of symmetry, slides, reflections (flips), rotations (turns), area, and perimeter. This lesson gives students a meaningful way to practice these...

High schoolers explore the concept of quadrilaterals. In this quadrilateral lesson, students play with a floor tile applet to see that there are many types and characteristics of quadrilaterals including parallelograms, trapezoids,...

Third graders explore vocabulary associated with three dimensional figures.  In this transformations lesson, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with describing two...

Third graders create a butterfly drawing that includes the elements of art and principles of design. They create artwork that can be made into ceramic tiles to be installed around the classroom doorways in our new addition.

Middle schoolers practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio...

Students visit a local lake refuge and identify shapes they find in nature. They take pictures of the various shapes and use KidPix to draw shapes around the shapes in the pictures. They watch a slideshow of all the shapes found by their...

Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...

Students examine transformations. In this math instructional activity, students view and describe flips, slides, and turns. Students practice making transformations with shapes.

Students 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...

Young scholars create an image using given coordinates and evaluate how the coordinates change when a slide or rotation takes place.

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...

Students identify and explore the attributes of polygons. They design and create a quilt square using polygons, and produce a class quilt.

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...

High schoolers perform dilation on various geometric shapes. They also discuss pros and cons of dilation and employ the Frayer Model to study the vocabulary words in this section.

Students create a bridge using engineering and geometric concepts. In this geometry instructional activity, students identify the missing measures of polygons sides and angles. They work together to solve real life situation using...

Students calculate the surface area of different prisms. In this geometry lesson plan, students identify the shapes of solids based on the properties of that solid. They calculate the surface area using nets and properties of prisms.

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 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.

Learners find the surface area of cones. In this geometry lesson, students calculate the dimensions of each three-dimensional shape and use the correct formula to solve the problem. They relate concepts of cones to the real world.

High schoolers identify the properties of a sphere. In this geometry lesson, students calculate the surface area of spheres using the formula derived by nets. They identify the radius and diameter of the sphere.
