Young scholars construct two-column proofs. In this geometry lesson, students use deductive reasoning and geometric properties to justify given geometric statements. Young scholars compare and contrast proofs.

For this lines and angles worksheet, students answer 10 multiple choice questions about lines and angles.

In this geometry worksheet, students identify the interior and exterior angles using the angle sum theorem. They identify and solve quadrilaterals using properties of quadrilaterals. There are 12 questions with an answer key.

Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.

In this online interactive math skills worksheet, learners solve 10 multiple choice math problems regarding geometry skills. Students may view the correct answers.

Young scholars conduct a review that is done right before having a geometry quiz. They cover major topics that are part of the assessment. They use review cards as notes to pass to one another to reinforce the concepts before putting...

Students explore similar figures. In this surface area and volume lesson, students identify the relationship between the surface area and volume of similar figures.

Students identify how tall a tree is. In this measurement lesson plan, students use "luminometers" to measure a tree and complete a data sheet.

Students discover math measurements by creating a skit with classmates.  In this geometry lesson, students utilize objects in a paper bag and index cards to create a short skit focusing on debate over the size of the objects....

In this measuring and classifying angles learning exercise, 6th graders select the type of angle (acute, right, obtuse, straight) for 6 drawings, then use a protractor to measure each angle.

For this quadrilaterals worksheet, students calculate the measure of angles in five parallelograms, name a quadrilateral, and find values of given variables in three diagrams.  The solutions are provided.

In this classifying and measuring angles activity, 10th graders solve and complete the measures of various types of angles. They determine whether each angle drawn is a straight, right, obtuse, acute, or reflex angle. Then, students...
