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...

Students explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

Is butter better? In terms of saturation, young chemists find out! Using titration methods, they will compare the degree of saturation of butter with that of margarine. Knowing the unsaturation, they can make conclusions about the...

Young mathematicians solve the volume using the disk method in this calculus lesson. They revolve a graph around the x-axis and calculate the volume. They use the TI to see the revolving around the x-axis and create a virtual cross...

Students calculate the volume of polyhedrons. In this algebra lesson, students are asked to solve a complex problem. They identify the length of the edges and the volume of the shape.

In this algebra worksheet, students manipulate integers to add, subtract, multiply and divide using order of operation. They rewrite word problems and solve for the unknown. There are 24 questions with an answer key.

In this geometry instructional activity, 10th graders determine the measures of various angle pairs:  supplementary, complementary, and vertical angles.  The two page instructional activity contains a combination of twelve...

In this calculus practice exam worksheet, students solve 16 multiple choice problems. Students find derivatives, points of continuity, area, rates, etc.

Sixth graders engage in problem solving, communicating, reasoning, and connecting to represent and solve problems, using geometric models.

In this Global Warming activity, students read the article, answer true and false questions, complete synonym matching, complete phrase matching, complete a gap fill, answer short answer questions, answer discussion questions, write, and...

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...

Provide your class some practice with the dimensions of geometric figures. Here you have a set of three different-shaped, stemmed drinking glasses with diameters and heights provided. Math-minded individuals calculate the volume of each....

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Fifth graders calculate the perimeters, areas, and volumes of everyday objects. They discuss the word problem involving Puck from the Shakespeare play "Mid-Summer Night's Dream," and invent and plan a method for solving the problem in...

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...

Use patterns to your advantage! The Pythagorean Theorem allows learners to find missing sides of right triangles. Problems include those with both rational and irrational lengths. 

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.

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...

A bird's life is one of danger and intrigue as it struggles for survival in sometimes harsh environments. To understand how difficult surviving in the wild can be, children play a simulation game where they act as little auks, birds from...

Students are introduced to the Pythagoras' Theorem and its history, proofs and practice in application. Students find perimeters, areas and volume of everyday objects. Students state and explain the theory.

Introducing ... the aerogel. The first of a two-installment series teaches young engineers about the properties and uses of aerogels. A PowerPoint presentation provides information about this unique material to help solidify the concept.

Begin seeing the world through the lens of geometry! Use the 19th installment in a 25-part module to apply the Pythagorean Theorem to solve real-world problems. Individuals sketch situations resulting in right triangles such as the...
