Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Students solve problems using the Pythagorean Theorem. In this geometry lesson, students identify the sides and angles of a right triangle. They find the different trigonometric ratios and solve using sine, cosine and tangent.

Students are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three concepts.

In this geometry activity, students identify segments and rays using sketches. They sketch intersection to a plane and describe the relationship of the segment and ray as it related to the intersection. There are 15 questions.

Students investigate image and pre-image. In this geometry lesson plan, students identify the reflection and rotation of different shape on a coordinate plane. They identify similarities and differences of image and pre-image of a...

Students draw on graph paper. In this geometry lesson, students review types of triangles and quadrilaterals. Students investigate geometric transformations, including translation, rotation and reflection. Students practice each...

Students measure planes and solids. In this geometry instructional activity, students find the area and perimeter of different polygons.They complete a word puzzle to review their vocabulary words.

Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.

Students define reflection, rotation and symmetry. In this symmetry lesson plan, students move the graph around the coordinate plane and identify the line of symmetry. They identify the different designs of a kaleidoscope.

Young scholars identify the properties of different polygons. In this geometry lesson, students find the slope of a line and calculate the distance between two lines. They differentiate between similar and congruent polygons.

Students explore geometry by participating in a shape rotation experiment. In this symmetry lesson, students identify the term symmetry and a list of other geometry vocabulary. Students analyze shapes as they are turned 90 degrees and...

Students perform translations on different polygons. In this geometry activity, students create figures that will be used as an assessment to represent transformation. They perform hands on creation and relate it to the real world.

Students collect data on population growth. In this statistics lesson, students graph their data and make predictions. They find the linear regression and the best fit line.

An upper-level treatment of what is often presented as a basic concept (the right angle of an inscribed circle on the diameter), this activity really elevates the mathematical thought of the learner! Expected to develop formulas...

Ninth graders design a safe passage through a 2-D obstacle. In this geometric math instructional activity, 9th graders engage in a hands on activity to better understand the concept of geometric and algebraic perpendicularity. Students...

In this plotting points on a graph learning exercise, students plot 6 points on 6 graphs.  Students plot x and y-coordinates in the first quadrant.

For this phone button boggle worksheet, students identify the number of math words they can find on a phone keypad according to given directions.  This one-page worksheet contains one problem.  Answers are provided.

Learners use the axes and measure angle tool to explore and calculate complementary angles with Cabri Jr. They also identify what happens to the calculation as they drag the endpoint into a different quadrant. Finally, they label each...

Students investigate the geometry concept of spatial relationships. They draw a replica of a cube. Students list the planes on the cube and go into further depth with identifying the parallel line in segments of the cube. The...

Students are introduced to plotting functions on the Cartesian coordinate plane seen several categories of functions, including lines and parabolas

Students, after reading the explanation given below, use FoilSim to determine the weight of the aircraft that can be lifted by a pair of wings of each type. They also design a unique platform of a wing to lift a plane weighing 11500 pounds.

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.

Fourth graders identify and describe lines, shapes, and solids using formal geometric language. They use Inspiration to create a graphic organizer and outline of polygons.

Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.
