Middle schoolers identify how many smaller units can be found in a later unit. In this geometry instructional activity, students calculate the volume and the transfer amount to a smaller unit. They solve real life problems using the...

Intended for beginners to geometry, an area of a rectangle problem has scholars draw out the units within the shape. They segment it into four rows and six columns to determine how many squares the rectangle is made of and, eventually,...

Looking to challenge your students that have mastered basic triangle congruence proofs? A collection of proofs employ previously learned definitions, theorems, and properties. Pupils draw on their past experiences with proofs to...

Medians, midsegments, altitudes, oh my! Pupils study the properties of the median of a triangle, initially examining a proof utilizing midsegments to determine the length ratio of a median. They then use the information to find missing...

It's assessment time! Determine your young mathematicians' understanding of elapsed time with this brief, five-question quiz.

Students investigate topology. In this Applied Science lesson students explore higher, more abstract mathematics using tangles. Students make topologically related shapes.

Here's an interactive that complements your lesson plans. Users of the resource adjust one of the angles in a complementary set to see how it affects the other. A set of challenge questions assesses understanding.

Soccer is all about angles. Young mathematicians use an interactive to correctly position the path of a soccer ball so that it reaches the goal. They consider complementary angles when answering a set of challenge questions.

Combine geometry and algebra concepts to solve a modeling problem. Young scholars consider the effect surface area has on volume. They write a cubic function to model the possible volume given a specific surface area and then...

Students measure and label specified angles. In this angles lesson, students use a protractor to find angles that are acute, obtuse, and reflexive. Students then label each angle and match the angles the correct definition. This lesson...

Sixth graders draw parallel and intersecting lines to observe and examine the characteristics of alternate interior angles, vertical angles, corresponding angles, and supplementary angles. Through observation, they discover the...

Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

Students calculate the distance formula. In this geometry lesson, students find the distance between two points on a coordinate plane. They identify the four different quadrants.

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.

Students investigate measuring as it relates to the real world. In this geometry instructional activity, students measure distances as they discuss fractals and how it relates to measuring. They measure both linear and non-linear distances.

Students investigate the rigid motions of reflection, rotation, translation, and dilation. This investigation be accomplished through classroom instruction and exploration using Geometer's Sketchpad.

Students identify the properties representing quadrilateral. In this geometry lesson, students differentiate between special and regular quadrilaterals. They discuss and demonstrate hierarchy of quadrilaterals.

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....

Fourth graders combine geometry and language arts skills while examining quilt-making. After identifying the geometric shapes contained in quilts, they write stories to encompass the quilt border. Students conclude by creating and...

In this inscribed angles worksheet, 10th graders solve 13 various types of problems related to inscribed angles in geometry. First, they identify a circle illustrated and each arc of the circle. They, students find the measure of each...

In this angles learning exercise, students answer multiple choice questions about different types of angles and measurements of angles. Students complete 6 questions total.

Third graders measure their feet and their parents' feet, record data on computer-generated graphs, and calculate and record mean, median, and mode.

Eighth graders calculate surface area of 3-D shapes. In this geometry lesson, 8th graders analyze cubes and prisms by finding their area and surface area. They compare the data of these two shapes.
