Middle and high schoolers participate in a seven-part lesson plan creating Escher-Esque tessellations. They demonstrate their knowledge of geometric transformations after viewing a PowerPoint presentation, conducting Internet research,...

Ensure your eighth graders get the most out of their math education with this series of Common Core checklists. Rewriting each standard as an "I can" statement, this resource helps teachers keep a record of when each standard was...

Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

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

There are four main topics in this bundle of lesson plans. They don't need to be taught sequentially. Each lesson has three parts: a starter, a main activity, and something to help consolidate and provide reflection on concepts learned.

Participants who use this resource will apply the Pythagorean Theorem to show whether or not the shaded triangle inscribed in a rectangle is a right triangle. Once all of the sides on the shaded triangle are found, it is important that...

Upper elementary and middle schoolers examine the Volumes of Similar Figures. They investigate the relationship between corresponding sides and evaluate the volume of similar figures. Pupils record their findings on various activity...

In this congruent figures worksheet, students answer 6 fill in the blank questions where they examine a pair of figures and determine if the figures in each pair are congruent or not congruent.

Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not. 

Fourth graders use tangram sets to investigate the congruence of shapes. They use congruent shapes to demonstrate the properties of slides, flips, and turns. They complete a math journal entry that describes and illustrates each concept.

In this similar polygons learning exercise, students identify the corresponding sides of polygons.  They use proportions to solve problems.  Students determine the scale factor of similar figures.  This two-page learning...

For this geometry worksheet, students select the shape that is congruent to the one given. There are four multiple choice questions for students to complete.

In this similar figures worksheet, students identify the meaning of similar, corresponding sides, and congruent.  They use proportions to find the length of a missing side.  Students dilate given figures according to a scale...

Students explore the concept of congruent triangles.  In this congruent triangles lesson, students use Cabri Jr. to construct two congruent triangles using circles.  Students determine if the two triangles are congruent by...

In this midpoint worksheet, students use a number line to find the midpoint of a line segment. Next, they find the midpoint of a line using the coordinate plane. Examples of how to use each method are given at the beginning of the...

Here is a geometry worksheet in which learners locate and identify various vocabulary terms related to geometry. There are twelve words located in the puzzle.

In this geometry lesson, young scholars trace the capital letter "T" in different directions to learn how a shape is congruent. Students trace this letter on a sheet of paper, then turn, flip it, and trace it in different directions,...

In this triangle relationships worksheet, students identify measurements in similar and congruent triangles. Each problem features a drawing of two or more triangles. Students identify missing measurements. There are 5 multiple choice...

In this prisms worksheet, students identify the number of faces in a prism.  They locate the parallel edges.  Students determine the names of prisms.  This two-page worksheet contains 3 problems.  Answers are...

In this problem solving worksheet, 4th graders study 4 lines of shapes. Students determine which multiple choice shape on the right is congruent to the one on the left of the straight line.

Learners explore the concept of paragraph proofs. In this paragraph proofs instructional activity, students make flow charts of the process of getting ready for school. Learners convert the flow chart to a paragraph proof. Students use...

Young scholars explore the concept of similarity and congruence. In this similarity and congruence instructional activity, students cut out strips of paper and form a triangle. Young scholars try to prove that their triangles are...

Students explore the concept of similarity and congruence. In this similarity and congruence lesson, students identify and verify whether or not two figures are similar, congruent, or neither. Students use postulates and theorems such as...

In this triangles learning exercise, 10th graders solve and complete 7 different problems. First, they list five ways to prove triangles congruent. Then, students name the method proving the triangles congruent in each problem.
