Young scholars identify the different parts of a right triangle. In this geometry lesson, students use the Pythagorean Theorem to identify missing sides and angles of a right triangle. They work with irrational and rational roots.

Pupils identify and sketch the nets for sphere. In this geometry lesson, students differentiate between two and three dimensional shapes. They find the surface area of each sphere.

Students identify the surface area of pyramids and other polygons. In this geometry lesson, students find the different measurements for the different parts of a polygon. They use the surface area formula to solve for the surface area,

Students identify the properties of a sphere. In this geometry lesson, students calculate the surface area of spheres using the formula derived by nets. They identify the radius and diameter of the sphere.

Fifth graders collect temperature readings over a period of time, enter the information into a spreadsheet and choose the appropriate graph to display the results.

Students become interactive participants in introductory and practice activities involving positive and negative numbers. After watching a video, students play games together which help them use positive and negative numbers effectively.

Learners interpret how to communicate information and ideas in ways that are appropriate to the purpose and audience through spoken, written, and graphic means of expression. They use information-gathering techniques, analyze and...

Fourth graders investigate one planet, enter information into a database, and print the database sorting for each of the attributes.

Students construct a book to illustrate number concepts. They write their numbers on a sheet of paper. Students in grade 1 discuss counting to 100 by different numbers. Pupils in grades (2-4) write basic addition or subtraction story...

Students calculate the costs for lodging and meals for a virtual field trip. They calculate the number of nights lodging needed for road and city travel and the number of meals needed, the costs for each, and input the data using...

Students role play being an international travel agent that is planning a trip for a client. The teacher gives specific details associated with the trip. They choose the destination and work out some of the other details. Students...

Students explore the concept of expressing numbers in scientific notation. In this scientific notation lesson, students understand the importance of using scientific notation by finding real world examples where scientific notation is...

Sixth graders explore geometric figures. In this geometry lesson, 6th graders manipulate properties and relationships of geometric figures to identify objects on the coordinate planes and describe where figures sit on the planes.

Students solve single variable equations. In this missing addend instructional activity, students solve problems with missing addends. Students create a function box to help study numerical reasoning.

Young scholars calculate how many quarters are in a $1,000 bag (after learning the dollar value of filled coin bags). They explain their problem-solving strategy using pictures, numbers, equations, and/or words.

Learners participate in a game blending skill with chance to enhance students' understanding of the concept of place value. They explain that the value of a number increases when digits farthest to the left have greatest value.

Students graph linear equations using intercepts, find y-intercept, find x-intercepts and graph linear equations that use horizontal and vertical lines.

Fourth graders measure the height and arm span of various classmates. They use a spreadsheet to design a graph that shows the class measurements from tallest to shortest in metric and standard systems.

Seventh graders research the World Wide Web to research and plan a garden for their school. They draw a scale model of the garden, determine the cost, and create a presentation to promote their garden plan.

Eighth graders examine common number system bases that are used: decimal, binary, octa and hex. They create a presentation about one of the number systems using the internet to research the topic. They solve mathematical computations.

Eighth graders demonstrate knowledge of metric tools by measuring common objects in the classroom. They discuss the various units of metric measurement and the scientific tools used to take them. They copy a metric ladder from a Web site.

Students investigate track and field dimensions, measure an actual track, and construct a scale model. The use of a meter stick, dimensional analysis, and the application of the distributive property to variables forms the main focus of...

Students solve systems of 2-by-2 linear equations using tables, graphs and substitution. In small groups, classmates work together to discover strategies for solving equations. They use a calculator to graphically represent their answers.

Learners 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. Learners use pegboards and string to create more...
