In this mathematics worksheet, learners give the area and perimeter of each polygon illustrated on the sheet. There are six different polygons to measure on the sheet.

Learners calculate the sides of right triangles in this trigonometric ratios lesson. They use Cabri Jr. software and TI-83 or TI-84 calculators to find the side lengths and their ratios to each other for various triangles. The provided...

For this three- and two- dimensional geometry worksheet, 7th graders solve 12 various problems related to geometric shapes and measurement. They first use paper and a pencil to sketch the front, side, back, top and bottom views of each...

Students use Geometer's Sketchpad to draw triangles and explore the classificaiton of each using the mearsures of interior angles and the lengths of the sides.

In this polygons instructional activity, students fill out a graphic organizer about the name of the polygon, the number of sides, the angle sums, and more. Students complete this for 5 polygons.

In this comparing shapes with vertices and sides learning exercise, students choose which of two shapes has more or less vertices or sides for 6 pairs of shapes.

In this trigonometry ratios in right triangles worksheet, 10th graders solve 6 different right triangle problems. First, they find the values of x and y in each triangle, rounding each to the nearest tenth. Then, students locate the...

In this special right triangles instructional activity, 10th graders solve 9 different problems related to measuring various types of right triangles. First, they find the values of x and y in each right triangle shown. Then, students...

In this tangrams instructional activity, 10th graders solve 7 different problems related to designing tangrams. First, they trace each of the figures shown on the sheet. Then, students cut out the pieces and rearrange them to form each...

Seventh graders use block letter writing to help classify polygons. They use their own names which helps to keep them engaged during the instructional activity. Finally, 7th graders play a classification game naming different polygons.

Students explore a variety of geometric shapes, name them, and list their characteristics. The shapes are transposed into structures and checked for accuracy.

In this triangles worksheet, students identify and name 3 different types of triangles. First, they determine the number of right triangles in the figure shown on the sheet. Then, students determine the number of equilateral triangles...

Eighth graders engage in hands-on activities to determine the surface areas of various objects. Using boxes, they cut them so they can lay flat and measure all the various shapes, which can be calculated and added together to equal the...

Explore and measure a variety of quadrilaterals.

This site is a personal site from David Eisenberg and it contains brief but great review information for trigonometry. This particular site focuses on sine and cosine inlcuding a small circle graph. Clicking on the index link provides...
