In this math worksheet, 10th graders solve problems involving a tangent line intersection the arc and forming various angles. There are 6 problems to be solved.

Here is a lesson plan that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and...

Learn how to calculate the length and midsegments of triangles. Students differentiate between similar and congruent triangles. They create a spreadsheet with their findings.

Calculus students use the derivative and integral to solve problems involving areas. They calculate the area under a curve as they follow a robot off road making different curves along the drive, using Riemann Sums and...

In this integers instructional activity, students solve 16 addition problems by adding two integers together. There is no answer...

Students make sensible estimates and check the reasonableness of the answers. Students write and solve problems involving decimal multiplication and division. Students perform calculations with time.

Students compute area.  For this perimeter, area and volume lesson, students examine given objects and determine the perimeter, area, and volume of each. 

Sixth graders participate in a lesson that is about investigating the different layers of the earth and defining how the plates move over the mantle. They engage in a variety of activities and use mathematics to create projects to...

Young scholars explore types of water reserves. For this water conservation lesson, students brainstorm ways water are used in their homes. Young scholars use a graduated cylinder to simulate the amount of water on Earth and the amount...

Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

High schoolers construct perpendicular bisectors using Cabri Jr. on their graphing calculator. They then construct conditional statements about perpendicular bisectors along with their converse, inverse, and contrapositive.

Learners investigate the area of various figures. They construct triangles and quadrilaterals using Cabri Jr. and discuss the relationships between different angles, side lengths, and figures.

High schoolers explore the concept of quadrilaterals as they find the midsegments of quadrilaterals using Cabri Jr. on a graphing calculator. They find midpoints, slopes, angles, and distances of lines and angles.

High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...

High schoolers investigate properties of the four centers of a triangle and explore a special property of the circumcenter and orthocenter of a triangle. This instructional activity requires the use of Cabri, Jr.

In this perimeter learning exercise, learners calculate the perimeter of rectangles.  This one-page learning exercise contains 6 perimeter problems.

In this area of polygons activity, 9th graders solve two area of rectangles, one area of parallelogram, and ten area of triangles problems.  The formulas for finding the area of these figures are provided.

Students visit different departments at a local hospital to see how machines help peoples such as the CAT scan machine. They build a model of such a machine that shows how patients are moved in and out of the machine.

Students explore the basic geometric shapes and geometric shape vocabulary through the use of geoboards and virtual geoboards. They create a variety of shapes with a partner, build ten different rectangles on their geoboards, and...

In this geometric calculations of solar storms worksheet, students use a diagram indicating the location of 2 STEREO satellites, the earth and the sun to calculate the distance between a Coronal Mass Ejection and the Earth. They use...

Students familiarize themselves with the three most common geometric shapes: circles, triangles and parallelograms. They sketch, sort, and name the shapes.

Students determine the distance between two points.  In this distance formula lesson, groups of students determine the distance between points in real life situations.  They calculate the distance from one point in the...

Learners use technology to determine the shortest between two points in a plane. They are required to support their analytic explanations with visual illustrations.

In this geometric figures instructional activity, 10th graders solve and complete 18 different types of problems that include various figures. First, they find the area of the figures shown if consecutive sides are perpendicular. Then,...
