Pairs of geometry whizzes work together to determine which of three differently shaped cylinders will have the greatest volume. Pupils cut out the three rectangles embedded in the plan, and tape them together to form a cylinder. From...

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

Middle schoolers redesign their school to make it more energy efficient, and create a model of their design. Learners get together in groups of 5, and they take on the task of making their school more energy efficient. To do this, they...

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Students develop an equation for finding the volume of a commonly known piece of candy (M&M, Hershey's Kiss, Tootsie Roll Pop, Life Saver, etc.) by using calculus.

Third graders use whole numbers and fractions to make connections between abstractions of the mathematical world and the real world. In this fractions and measurement lesson, 3rd graders identify, quantify groups , and measure distances....

Students discover the relationship between the circumference of a circle and its diameter. They find the length of an arc of a circle.Students use estimation strategies in real-world applications to predict results (i.e., interpolation...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Third graders create a box big enough to hold a million dollars. This is a project fun to do near the winter holidays with inexpensive gifts included in the boxes. This hands-on lesson very effectively demonstrates the concept of volume.

Students design a collage of pictures for a yearbook that make a shape. They determine the area of the shape and the price of putting the collage in the yearbook.

Students discover the relationships of the lengths of the sides of right triangles and right triangles using a series of drawings on dot paper. They investigate and solve problems of standard (customary and metric units) and non-standard...

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

In this online interactive math skills worksheet, students solve 10 multiple choice math problems regarding geometry skills. Students may submit their answers to be scored.

Students identify he proportion of a cereal box. In this algebra lesson, students define the relationship between patterns, functions and relations. They model their understanding using the cereal box.

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 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 enter a race against time to determine the maximum sized box that can be formed from a standard sheet of copy paper. The boxes are to be used to contain a valuable and rare element which is light as cotton and corrosive to all...

Students compute the area of triangles in a computer program. In this measurement lesson plan, students complete 5 easy, 5 medium, and 5 hard problems.

Fifth graders determine which container made from a single sheet of paper has the greatest volume. They look the solutions made by three different students before working on their own examples.

Ninth and tenth graders calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They solve problems involving scale drawings, models, maps or...

Learners identify the stages of the water cycle. They listen to the book "Magic School Bus: Wet All Over," examine the Build Your Own Water Cycle website, predict and measure the amount of water in a jar for a week, and read a short play...

Estimate the value of one of the most famous irrational numbers. The hands-on instructional activity instructs classmates to measure the circumference and diameters of circles using yarn. The ratio of these quantities defines pi.

Get creative juices flowing when you allow groups to figure out a procedure for how to find the area of squares and rectangles. They may use the individual patchwork blocks, or they may design one using the Design Template.

Explore types of angles and the characteristics of each. After observing a PowerPoint Presentation, learners tour the school facilities and use a digital camera to capture prescribed angles. Using the digital pictures and written...
