Geometry Teacher Resources

In this geometry skills learning exercise, students examine 6 geometric figures and identify them as spheres, cylinders, cones, or cubes.

In this geometry skills learning exercise, students examine 6 geometric figures and identify them as spheres, cylinders, cones, or cubes.

In this geometric shapes practice worksheet, students respond to 6 geometry questions that require them identify spheres, cubes, rectangles, and pyramids.

In this geometry skills worksheet, students respond to 4 questions that require them to examine geometric figures and change them to solid figures and plane figures.

In this geometry worksheet, learners check either flip, turn or slide next to a letter to determine which has been done to it. A reference web site is given for additional activities.

In this geometry skills practice worksheet, students respond to 6 questions that require them to identify whether the 6 images pictured are symmetrical.

In this geometry worksheet, students match terms with definitions, and complete short answer questions about polygons and congruency.

Use half the length to connect the midpoints. A section of a playlist on geometry introduces the concept of a midsegment of a triangle and how to find it. The video states the properties of the midsegment which make up the Midsegment...

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...

Point out an application of Pythagoras. The segment of an essential playlist on geometry provides a quick review of the Pythagorean Theorem. Using a right triangle to show the positions of two points, the presenter calculates the...

Get the slope right with two easy steps. By placing two perpendicular lines on the coordinate plane, the video determines the relationship of the slopes of the two line lines. The resource is a part of an informative and extensive...

Multiply coordinates to either shrink or enlarge a figure. An informative segment of a geometry playlist introduces dilation on the coordinate plane. The dilations in the resource use the origin as the center of dilation, which makes...

Develop a prime example of sliding about the coordinate plane. Using figures on the coordinate plane, a segment of an extensive geometry playlist introduces the transformation of translations. The presentation uses coordinate notation to...

Change places by pivoting the figure. The section of a geometry playlist introduces rotations by making the connection to rotational symmetry. The presentation provides formulas to use with the coordinates when rotating a figure around...

Challenge: create an assessment that features higher level thinking from beginning to end. A ready-made test assesses knowledge of dilations using performance tasks. Every question requires a developed written response. 

Increase the level of assessment rigor with the test of performance tasks. Topics include similar triangles, trigonometric ratios, Law of Sines, Law of Cosines, and trigonometric problem solving. 

It's test time! Determine your class's understanding of the topics of volume and cross sections with a thorough assessment on volume, area, and geometric shapes.

How can you formally assess understanding of circle concepts? Pupils take a mid-module assessment containing five questions, each with multiple parts.

The lessons are complete. Learners take an end-of-module assessment in the last installment of a 23-part module. Questions contain multiple parts, each assessing different aspects of the module.

How do you prepare class members for the analytical thinking they will need in the real world? An assessment requires the higher order thinking they need to be successful. The module focuses on the concept of rigid transformations...

Discover how to analyze architecture from a geometric standpoint. The fourth installment of an 11-part unit on architecture first provides a presentation on axis, balance, basic form, formal, pattern, proportion, symmetry, and tripartite...

To work through the complexity of coordinate geometry pupils make the connection between the coordinate plane and the complex plane as they plot complex numbers in the 11th part of a series of 32. Making the connection between the two...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson plan series supports children with learning how to measure the area of squares, rectangles, and...

In this congruent triangles worksheet, young scholars solve four multiple choice problems. Students determine which statement is the appropriate reasoning to say that two triangles are congruent.
