Elementary schoolers utilize a pattern worksheet embedded in this plan to work on a deeper understanding of geometric concepts like symmetry and congruency. Since geometry is such a visual form of mathematics, this lesson should fit...

Dedicate one or two class periods to creating a class glossary of geometry terms. Many geometry terms also appear in our every day vocabulary, but they have very different meanings. For example, the word gross in geometry is very...

How do you build a polygon from an inequality? An engaging lesson challenges pupils to do just that. Building from the previous lesson in this series, learners write systems of inequalities to model rectangles, triangles, and even...

Students use geometric shapes to describe body parts. In this geometry lesson, students use geometry vocabulary as they discuss body parts. They practice drawing bodies using shapes based on a wooden model that is poised to show specific...

Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this lesson. They make a set of tangrams and use them to compute area. They use...

Use shapes to visualize fractions! Elementary learners color 1/2, 1/3, 1/4, 1/8, and 1/10 of various shapes. A great addition to your fractions lesson, or to introduce geometry in your math unit.

This is an interesting geometry problem. Given the figure, find the area of a triangle that is created by the intersecting lines. The solution requires one to use what he/she knows about coordinate geometry, as well as triangle...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Can segments be considered perpendicular if they don't intersect? Learners look at nonintersecting segments on the coordinate plane and make conclusions about the lines that contain those segments. They determine if they are...

Research the interrelationship between math and science. Search the Internet to discover the history of several branches of mathematics and make text-to-world connections between the concepts covered in each branch with related...

Explore geometry with your young mathematicians! First, have them color in different two-dimensional and three-dimensional shapes. Then take them on a walk around the classroom. Can they identify different shapes using the target...

Geometry can be fun when you know the shapes! Twelve pictures of geometric shapes, including cones, pyramids, and spheres, prompt first graders to write the name of each shape in the space provided. Use the activity as a quiz or homework...

How do you show that something is a rectangle? This activity starts with four coordinate points and asks young geometers to explain whether they create a rectangle. Knowledge from both geometry and algebra come into play here, as well...

Your Geometry learners will collaboratively prove that the tangent line of a circle is perpendicular to the radius of the circle. A deliberately sparse introduction allows for a variety of approaches to find a solution. 

No need to change anything about the resource. The first of eight modules in the MVP Geometry unit focuses on transformations in the coordinate plane. It connects translations, rotations, and reflections to congruence, symmetry, and...

Construct yourself a winning geometry unit. A set of lessons introduces geometry scholars to constructions and proofs with compasses and straightedges. It also covers triangle congruence through transformations. This is the second of...

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

Investigate relationships between angles, arcs, and segments in circles. Pupils use geometry software to discover the relationships between angles, arcs, and segments associated with circles. Class members use similar triangles to...

Take your math lesson to another dimension with this lesson about 3-D shapes! First graders label cones, cylinders, pyramids, spheres, cubes, and prisms, and then count the number of each shape in a collective picture. A great way to...

Students explore inequalities to determine the optimal solution to maximize a profit for a company. In this linear programming lesson, students discover how to graph inequalities and how to determine the algebraic representation of a...

Can your kindergartners recognize shapes? What about when they are in different orientations? Youngsters study groups of shapes to determine which have the same shape and size. Two of the groups have triangles and ovals, and the other...

This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

Students investigate geometric relationship using conjecture about linear pairs and vertical angles. In this geometry lesson, students apply their theorems and previous geometry knowledge to solve for and find angles of linear...

Geometric design makes a fashion statement! Challenge learners to design a hat to fit a Styrofoam model. Specifications are clear and pupils use concepts related to three-dimensional objects including volume of irregular shapes and...
