Get into springtime with a festive practice sheet designed to test scholars' knowledge of grids. Learners locate items such as watering cans, snails, and flowers following the x and y-axis. Worksheet themes include Earth Day, gardening,...

Young scholars make three dimensional shapes with nets. In this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They...

Students investigate properties of circles. In this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Several practice exercises suitable for any geometry class working on transformation, symmetry, and tessellation -- especially visual representations of image translation, rotation, and reflection, symmetry, tessellations and tangrams --...

Tenth graders define the formula for cylinders and use it to solve real world problems. In this geometry lesson plan, pupils differentiate between area, perimeters, 2D shapes, 3D shapes, and volume of prisms, cylinders and spheres. They...

This geometry idea is simple enough, but you'll need to note the typos in the directions. Learners match quarters and halves on the right to their whole shapes on the left. The shapes on the left are divided to make this concept easier...

In this polygons worksheet, students put a polygon jigsaw puzzle back together to form the planet Earth. Students put 10 polygons together.

In this lines and planes worksheet, students answer eight true and false questions telling if two line segments are parallel or in the same plane. Students tell the line on the intersection of two lines and name the plane the lines are on.

In this area of a parallelogram worksheet, 10th graders determine the measurement of 10 different parallelograms illustrated. First, they multiply the base of the parallelogram times its height to determine the area. Then, students...

In this polygon activity, middle schoolers observe pictures of polygons and identify their proper name. They read descriptions of polygons and determine the polygon described. This one-page activity contains ten problems.

In this polygons worksheet, students fill out a graphic organizer about the name of the polygon, the number of sides, the angle sums, and more. Students complete this for 5 polygons.

Learners recognize and name two-dimensional and three-dimensional geometric figures. One group of students will extend the study of polygons to quadrilaterals while another group of learners will extend the study of polygons to...

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

Fifth graders, using graphic and word processing software, create geometric patterns by performing elementary transformations.

Students choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.

Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.
