Second graders design a scale model of a medieval castle and its surroundings including the following items: castle, moat, bailey, drawbridge, turrets, dungeon, grounds, and outer walls. A perfect lesson for those kids who are fascinated...

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

Students solve problems using geometric means. In this geometry lesson, students create altitudes in right triangles. They use Cabri software to move the triangle around and observe different sides and angles.

Pupils define properties of rectangular prisms. In this geometry instructional activity, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.

Students explore the Earth's crust by researching pH levels and acidity. In this environmental safety lesson, students identify the pros and cons of acidity within soil and how it affects plants. Students collaborate in a pH level...

In this Pythagorean theorem worksheet, 9th graders solve and complete 8 different problems that include using the Pythagorean theorem to solve. First, they find the missing measure in each right triangle. Then, students make a drawing...

In this trigonometry activity, learners find the lengths of triangles. They construct triangles and spirals. Students complete indirect measurement problems. They find the distance between objects and determine the volume of rectangular...

For this area worksheet, students solve for the area of rectangles, parallelograms, triangles, trapezoids, kites, regular polygons, circles, and surface area.  The worksheets is divided into seven different sets of problems.

Students participate in a instructional activity designed to illustrate these concepts using simple materials. They use Science process skills to observe, measure, predict, make inferences, and communicate while completing the activity....

Students study relationships between angles, side lengths, perimeters, areas and volumes of similar objects. In this lesson students also create and critique inductive and deductive arguments concerning congruency, similarity and the...

Students model the geometric relationship with graphing. In this geometry lesson, students differentiate between parallel, perpendicular, similar and congruent shapes. They use properties of polygons to differentiate their shapes...

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...

Students explore properties of tangent lines.  In this properties of tangent lines lesson, students discuss the perpendicular relationship between a tangent line on a circle and the circle's radius.  Students use that...

Eighth graders investigate the Pythagorean theorem and how it is used in geometry. Measurements for different triangles is given and then students must solve problems in order to practice using the formula.

Students experiment with a simple periscope to see how it reflects light. They draw a diagram of the path a ray of light follows as it travels from an object, through the periscope, and into your eye.

In this math worksheet, students examine the measurements of a Pizza Hut box. Then they draw out the box and answer questions about its volume.

In this Pythagorean theorem worksheet, learners determine if given side lengths for right triangles, find the length of the missing side in right triangles, and find the length of the diagonals formed in boxes given side lengths.

Students identify lines, and line segments. In this geometry lesson, students divide line segments into equal congruent parts. They complete a laboratory activity dealing with lines and segments.

Ninth graders select and build one of five different paper airplane designs and test them for distance and for time aloft. Part of this activity is designed to explore NASA developed software, FoilSim, with respect to the lift of an...

Fourth graders calculate the angles and construct a pie graph of the percentages of the elements in the continental and oceanic crusts. Then they analyze the results. They can be assigned the task of researching the percentages.

Students compare the lengths of whales using different lengths of rope. They illustrate one whale in life-size proportion.

Students examine the idea of "regularity" as it pertains to geometry.  For this geometry lesson students complete several assignments that are part of trihedral angles and regular polyhedrons.

In this triangle learning exercise, students draw the type of triangles described, 4 total. Space is provided for student's drawings. A reference web site is given for additional activities.

Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.
