In this perimeter worksheet, students calculate the perimeter of L-shaped figures by subtracting to find missing side lengths.  There are 6 questions.

Second graders examine two-dimensional shapes using their characteristics. In this shapes lesson, 2nd graders identify similarities and differences by using cut out shapes, diagrams, mirrors, and graphic organizers.

In this calculating area of compound figures worksheet, middle schoolers solve 4 problems that require them to find the area of compound shapes.

For this algebra worksheet, 10th graders apply inductive reasoning as they figure out the next number in the sequence or pattern. There are 53 problems.

Fifth graders measure specified distances when given perpendicular lines. In this measurement lesson plan, 5th graders draw the lines themselves.

Learners 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 investigate patterns and functions. In this algebra lesson, students examine the repetition of integers and objects. They create formulas for the repetition and identify them as function using equations.

Students solve problems using patterns. In this algebra lesson, students identify the relation, domain and range of a function. They graph functions using coordinate pairs.

Students observe a pendulum and graph their observation. In this algebra lesson, students use the TI calcualtor to graph the motion the pendulum makes. They analyze the graph and make predictions.

Students identify the parts of an engine using a graph. In this statistics instructional activity, students make a graph from their collected data. They calculate the volume of a cylinder using a line of regression...

Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.

Students connect different mathematical concepts. They create a circle graph. Students then create a question in which they collect data in order to convert fractions to decimals and decimals to percents.

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Students work together with a partnet to design a building. Using materials, they create the inside and outside of the structure along with works of art. They present their creation to the class and receive constructive criticism in return.

Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...

Pupils explore the concept of fractals. In this fractals lesson, students use the website to research where fractals occur in nature. Pupils research what fractals are and how fractals are used to solve real world problems.

Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.

Fourth graders work in co-operative teams of four to complete a puzzle. Each student initially works independently, and then the team jointly puts together the four shapes they have individually made, to complete the puzzle.

Fifth graders describe and demonstrate how trigonometry can be used to find the height of a tall building or tree. They describe and demonstrate how trigonometry can be used to find the height of a high hill, or other high object where...

Second graders be having hands-on experiences with three-dimensional solid shapes. They investigate the features of solid shapes and examine the names for them. They are introduced to making nets for 3D shapes.

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

Pupils study the meaning, symbolism, and value of U.S. coins, especially the quarter. They conduct a survey of coins in students' possession, graphing the results to show frequency distribution and drawing inferences about the U.S....

Students participate in a hands-on activity that shows the independence of perimeter and area for simple irregular figures.

Students in a teacher education class address consumer related issues involving packaging. Using volume, surface area and graphs, they create a package for a given volume of a product. They design modifications for this lesson and to...
