Students create polygons using geometers sketchpad. In this geometry lesson, students construct the interior angles of polygons and label the different points. They estimate and measure the different parts as they draw conclusion.

Students estimate and measure exact. In this geometry instructional activity, students create different object in three-dimensional pattern. They use SketchUp to create their shape and perform measurements on their shapes.

In this distance worksheet, students calculate the lengths of sides and diagonals of figures.  Students also compute lengths in shadow problems.  The solutions are provided by clicking on the "show answers" tab at the bottom of...

Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...

Using a twelve foot knotted rope, students form a 3-4-5 right triangle. Following a discussion of observations about the lengths of the sides of the triangle, students use grid paper, scissors and a centimeter ruler to draw and measure...

Learners find locations based upon their latitude and longitude coordinates. In this latitude and longitude lesson, students locate points on a grid and learn how to use an astrolabe.

Fourth graders explore geometry by utilizing pattern blocks. In this pattern lesson, 4th graders analyze two separate pattern block shapes and discuss which one is bigger and smaller. Students collaborate in small groups to create...

Students identify, compare and classify the various shapes. In this shapes instructional activity, students listen to descriptions of shapes with words such as sides, angles, congruent, and parallel. Students then give the teacher...

In this area and perimeter worksheet, students find the length or area of seventeen figures.  The figures examined are triangles, trapezoids, parallelograms, rectangles, and hexagons.  Some examples and solutions are...

In this algebra using proportions worksheet, 10th graders solve 14 various types of problems by applying algebra methods to geometry. First, they solve each of 8 proportions using cross products. Then, students use the triangle shown and...

Students create paper bridges. For this geometry and architecture lesson, groups use legal paper and paper clips to design a bridge that will hold 100 pennies. Links to mini-lessons exploring stability of different geometric figures and...

In this compound locus worksheet, 10th graders solve and complete 10 different problems related to compound locus. First, they determine the number of points in a plane that is units from a given line and from a given point on a line....

In this compound locus worksheet, 10th graders solve and complete 10 different problems that include compound locus. First, they determine the number of points in a plane given the units from a given line and a point on the line. Then,...

Young scholars watch videos and fill out worksheets about the turtles and their journey to the Costa Rican beach. In this turtles lesson plan, students learn and discuss survival, predator and prey, and stages of development.

Third graders get into groups of two. Next, give each student a piece of butcher paper that is long enough for them to trace their entire body. One person lies down while their partner traces the outline of their body. Upon completion,...

In this measurement worksheet, students complete a 12 question multiple choice online interactive assessment about standard modern and ancient measurement.

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...

Students explore the relationships between similar figures. In this relationships between similar figures lesson, students discuss relationships between perimeter, circumference, area, surface area, and volume of similar figures through...

Students investigate geometric shapes in their environment, make a geometric design, and write paragraphs describing the design.

Students draw diagrams demonstrating how it is possible to two central angles to be congruent and their minor arcs are not congruent. In groups, they illustrate theorems with their constructed circles, create diameters of circles that...

Learners use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings

Sixth graders draw parallel and intersecting lines to observe and examine the characteristics of alternate interior angles, vertical angles, corresponding angles, and supplementary angles. Through observation, they discover the...

Fourth graders construct squares and rectanges in order to help them find areas and perimeters. They gain an understanding of area and perimeter through teacher modeling and then they construct squares and rectangles.
