For this postulates and theorems worksheet, students explore a concept map containing information about angles and sides, alternate interior angles, and diagonals of a parallelogram.  They use the concept map to prove theorems...

Students explore the relationship of angles as it relates to 2 and 3-D shapes. For this geometry lesson, students differentiate between acute, obtuse, right, alternate interior, exterior and adjacent angles. They manipulate a math...

Where do the coordinates lead? As children brainstorm ways to find the location of different buildings, they learn about coordinate points and how to use them to locate areas on a grid or map. They practice using ordered pairs by playing...

For this parallel lines with a transversal worksheet, students identify angles as corresponding, alternate interior, or alternate exterior, find the measure of angles, and solve for indicated values.  The solutions are provided.

In this compounds worksheet, students complete a graphic organizer by filling in the chemical compounds structure, resonance, geometry, hybridization, and bond angles. Then students complete 2 short answer questions.

In this geometry worksheet, students identify the different angles formed by cut parallel lines. They name the angles and find the measures of each. There are 24 questions.

Just what does it take to show two rhombuses are similar? The assessment task asks pupils to develop an argument to show that given quadrilaterals are rhombuses. Class members also use their knowledge of similar triangles to show two...

Is the amount of information getting overwhelming for your geometry classes? Use this strategy as a way to organize information. The resource provides a handout of information studied in relation to triangle congruence. It includes a...

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),...

What figure is formed by connecting the midpoints of the sides of a quadrilateral? The geometry assessment task has class members work through the process of determining the figure inscribed in a quadrilateral. Pupils use geometric...

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

Create the ultimate miniature golf course. The 93-page model curriculum unit from the Massachusetts Department of Elementary and Secondary Education contains nine lessons on understanding similarity in terms of both Euclidean geometry...

Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...

Students represent and solve problems using geometric models and apply geometric properties and relationships. They also practice constructing and measuring angles. By constructing, drawing, visualizing, and comparing geometric figures...

Students broaden their outlook on geometry in their everyday environment. They explore the properties of parallel lines and parallelograms and discover ways to prove the existence of parallel lines and discuss the concept of parallel lines.

Investigate geometric reflections in this geometry lesson. Create geometric reflections that show the reflection across the x and y axis of a coordinate graph. Learners watch a teacher demonstration before proceeding on their own. They...

In this triangle worksheet, students solve 1 word problem about the lengths of a triangle. Students determine the length of the longest side given the ratio of the angle measures.
