Students identify the relationship between the radius and Pi. In this geometry lesson, students calculate the circumference and area of a circle. They create visuals to help them see how the circumference relates to Pi.

Students practice determining the most appropriate units for a given situation while measuring attributes of objects, systems and processes of measurement. They review the concepts of angles, perimeter, area, surface area and volume.

Students perform translations and reflections. In this algebra lesson, students use the TI calculator to graph functions. They move the functions around on the coordinate plane using translation and reflection.

Students work with given formulas to solve for specific variables. The calculation of the volume of a cylinder and the change in volume when there is a constant surface area is analyzed in this lesson.

In this mental math activity, students calculate area, volume, perimeter, and convert units in two mental math tests of ten problems each. 

Young scholars estimate, calculate, and count back the amount of change needed from purchases made during small group activities.

Second graders publish a class cookbook of their own recipes. They explore the nutritional value of foods, calculate the measurements, and prepare a healthy recipe for the class.

Fifth graders find perimeters, areas, and volumes of everyday objects and state the precision. They work in small groups in order to take measurements, perform calculations, and write a group report about the investigation.

Students discover the concept of elapsed time. In this calculating time lesson plan, students utilize the Internet to complete record sheets based on the concept of elapsed time. Finally, the students answer questions on their own.

In this geometry worksheet, students calculate the midpoint and distance between two points. They use the correct formula to solve the area and perimeter of polygons. There are 20 multiple choice questions with an answer key.

Students solve for the area and perimeter of polygons. For this geometry lesson, students identify repeated patterns and create formula to solve problems. They make conjectures and prove hypotheses.

Learners calculate the height and altitude of a pyramid. In this geometry lesson, students define the parts that make up a pyramid. They use the Pythagorean Theorem to find the missing parts of a pyramid.

You're going to wish you had a watermelon for this lesson! Class members read about watermelons and make a salad in class to sample. They also perform estimates, measurements and calculations on a watermelon. They predict what percentage...

In this geometry worksheet, 10th graders identify different parts of a scalene triangle and calculate the length of different segments. There is one question with an answer key.

Students solve problems with percents, decimals and fractions. In this algebra lesson, students convert between fractions, percents and decimals. They estimate their answers and calculate their answer.

Students calculate the distance from the vertex of a triangle to the center. In this geometry lesson, students find the shortest distance between a point and the vertex of a triangle. They relate this concept of distance to the real world.

Learners explore the concept of area. In this area lesson plan, students find the area of irregular shapes with right angles. Learners break down each irregular shape into multiple regular shapes in order to find the area. Students...

Fourth graders work in a group of 4 to make rectangle with a 12m length of string. They discuss its perimeter and how they would calculate its area. Then another group of 4 make another rectangle and estimate if the area would be greater...

Sixth graders apply problem solving strategies to work with a real life situation in which they need to determine the area. They determine the area of chicken runs that are rectangular in shape when give a partial perimeter.

Young scholars need to be able to calculate the volume and surface area of a cuboid as well as present a systematic list of results in order to justify the minimum case. The use of three factors of 100 is also important.

Students compare, classify and calculate the area of geometric figures such as rectangles, squares, circles and triangles.

Sixth graders derive an original formula for calculating the area of an irregular figure.

Students discuss how big is big. They compare the area and perimeter of an acre and a football field.

Students visit various websites to calculate the area of circles, triangles, rectangles, trapezoids, and parallelograms. They explore math problems and play interactive games dealing with geometry.
