Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are...

Tenth graders investigate the early history of geometry. For this geometry lesson, 10th graders investigate translations, rotations, and reflections. They also solve problems with line of symmetry and rotational symmetry while reviewing...

High schoolers explore geometry using a Rubik's Cube. For this 2-D and 3-D shapes lesson, students use the Rubik's Cube to find the center, edge and corner pieces. High schoolers then find the dimensions of the Rubik's Cube and read the...

Second graders participate in Math-Eze activities to comprehend word problems. For this word problem lesson, 2nd graders recognize why a hexagon is the best shape for a beehive. Students calculate how far bees must travel to find 2 lbs....

Learners construct a variety of right triangles using a right-angled set square, cutting corners from pieces of paper or cardboard, and using dynamic geometry software. They measure the sides of these various right triangles and record...

Excellent lesson! Anne Linehane's geometry story, The Greedy Triangle, offers an opportunity to practice forming various types of polygons with your learners. Using elastic bands (or Chinese jump ropes),...

Geometric shapes are used in math and in art. Learners discuss the various names, dimensions, and attributes of geometric shapes, then apply that knowledge to design a vase. They use 3-D shapes to make a cubist-style vase out of clay.

One of the hardest skills for many young geometers to grasp is to move beyond just declaring obvious things true, and really returning to fundamental principles for proof. This brief exercise stretches those proving muscles as the...

Explore the geometry of treasure hunting! Learners use geometry to design a treasure recovery strategy. The objective is to create a design that minimizes the amount of work required. Budding mathematicians use properties of triangles as...

Use this volume of solids lesson to have learners find the surface area and volume of cylinders, pyramids, and prisms. They place cubes inside three-dimensional figures to determine the volume. Worksheets and answers are provided.

Middle schoolers respond to Tony Smith's sculpture as art and brainstorm about math concepts inherent in his work. They create a sculpture with polyhedra nets, calculate the cost of covering sculpture in gold, and write an exhibit label...

In this math worksheet, students read the examples for using the techniques of mathematical modeling. They draw the angles in order to simulate the reflection of light while using a concave mirror.

An outstanding lesson on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle...

Second graders experiment with slides, flips and turns to understand motion geometry.  In this motion geometry lesson plan, 2nd graders navigate interactive motion geometry sites. Students  illustrate the results of motion...

Students examine the concepts of geometry used by Paul Goble in his book Adopted By The Eagles. After analyzing Mr. Goble's work they create an original piece featuring symmetry, pattern, repetition, and other principles of geometry....

Students use geometry to create art. In this geometric graphing and patterns lesson, students create a helix-a-graph by plotting points on a grid that follow a certain pattern and analyze the drawing they created.

Students explore geometric shapes.  In this kindergarten geometry lesson, students create a fall quilt consisting of three different paper geometric quilt squares that when assembled form a scarecrow, a pumpkin, and a crow. ...

Students investigate spherical geometry using a globe and an apple. In this spherical geometry lesson plan, students translate Euclidean geometry terms to spherical geometry terms using a globe. They answer 3 questions about spherical...

Students review the parts of a circle, calculate the circumference and area of a circle, and create student-made tests on the geometry of circles using educational software.

Students explore points, lines and planes as it relates to geometry. In this geometry lesson plan, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.

Third graders investigate shapes in our world. In this geometry lesson, 3rd graders describe plane and solid shapes and identify angles, solid objects and lines of symmetry. Students use online resources, graphic organizers and conduct...

Students practice calculating probability, see how geometry can help solve probability problems and explore platonic solids.

First graders explore eight geometry activities that improve understanding of positional words and shapes. They identify, describe, and create simple geometric figures. They help another student who may not understand the concept yet.

Students examine the relationship between probability and geometry to solve problems. In this geometry and probability instructional activity, students investigate the effect of changing percentages on a spinner to the probability of...
