Learners investigate properties of similar figures. In this properties of similar figures activity, pupils construct similar figures using Cabri Jr. They dilate their figure to create a similar one, and discuss the relationships between...

No two resources are exactly the same, but polygons can be. Scholars match congruent figures by dragging them together in an interactive. They answer some challenge questions that justify their matches.

Let's move into the third dimension! Learners explore the vocabulary and notation related to three-dimensional figures. The video covers examples of pyramids, but the vocabulary is universal to all 3-D objects.

Math whizzes examine the shape properties on a coordinate grid and explore how the coordinate system enables us to discover the properties of shapes and the relationships among points in a geometric plane. They connect graphic locations...

In this congruent figures instructional activity, students examine 3 pairs of figures and determine if they are congruent. Students then draw figures that are congruent to a square and a triangle. Students identify isosceles triangles....

Students investigate properties of trapezoids. In this properties of trapezoids lesson, students construct a trapezoid three different ways. Students derive the area formula for a triangle from the area formula for a trapezoid. Students...

Introduce your class to 17 different polygons and their properties with this resource. Learners examine a list of polygons and brief definitions presented to them and write how many lines of symmetry, vertices, angles, and right angles...

In this properties of 3-D shapes worksheet, students identify shape, faces, edges, vertices, and right angles. In this fill in the blank worksheet, students answer thirty-six problems.

All triangles have some things in common. Using these properties of triangles, learners find missing angle measures. Scholars use the Angle Sum Property and properties of special triangles throughout the lesson.

Does the symmetry and transitive property apply to similarity? The 10th segment in a series of 16 presents the class with a group of explorations. The explorations have pairs show that similarity is both symmetrical and transitive. It...

From the apple on your desk and the coffee cup in your hand, to the cabinets along the classroom wall, basic three-dimensional shapes are found everywhere in the world around us. Introduce young mathematicians to the these common figures...

Practice the properties of lines in the coordinate plane. Young mathematicians use Cabri on their graphing calculator to determine the slope ratios. They use the change in y-coordinates/change in x-coordinates. Additionally, they find...

Providing a real life component to the study of geometric shapes, pupils take the lesson plan outdoors. They use a digital camera to take pictures of the geometric shapes they see at and around their school. Then they create a...

Build a definition of congruence from an understanding of rigid transformations. The lesson asks pupils to explain congruence through a series of transformations. Properties of congruence emerge as they make comparisons to these...

If you know two values and are looking for a third, you can set up an equation and solve to find your answer. In this problem you know distance and time, and you are looking for rate of speed. Use the distance formula to set up your...

If you know two values and are looking for a third, you can set up an equation and solve to find your answer. In this problem you know distance and time, and you are looking for rate of speed. Use the distance formula to set up your...

A word problem, chemistry, and percent? I know you want to throw your hands in the air and run away from this problem, but please don't. Pay close attention as the instructor helps you unpack this word problem to set up an equation that...
