In this special right triangles worksheet, 10th graders solve 7 various problems with various types of right triangles. First, they identify the two special types of right triangles, the 45-45-90 degree triangle and the 30-60-90 right...

Young mathematicians calculate the area of polygons in this algebra lesson plan. They find the determinant as they calculate the areas for triangles and quadrilaterals. They also use scalar multiplication to find the determinant.

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...

Learners play a game with shapes. They work in groups to identify the names and characteristics of various shapes. They give each other clues to see if others can identify the shape being described. This is a great hands on activity.

Students explore geometry by drawing various shapes in class. For this triangle characteristics lesson, students identify the attributes that classify a shape as a triangle and practice using their bodies to create triangles in class....

In thins triangles review worksheet, students examine 4 triangles and their measurements. Students classify them as equilateral, isosceles, or scalene.

In this angles practice worksheet, learners respond to 4 questions that require them to identify the pictured angles as acute, right, or obtuse triangles.

Students identify and categorize different polygons. In this polygons lesson plan, students research and identify properties of polygons,  identify different polygon shapes, and categorize different triangles and quadrilaterals.

Here is a lesson 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 then...

What a wonderful resource! Learners create two-dimensional shapes according to the instructions stated, use the squares to make a triangular prism, a cube, and a pyramid, and identify features of plane shapes, among a myriad of other...

Students view several different types of triangles. They discuss attributes of a triangle with a partner. Students use a straw cut into pieces to create a triangle. They complete a Triangle Hunt worksheet (teacher created). Students...

Students identify geometric solids. In this geometric shapes lesson, students listen to the teacher read Captain Invincible and the Space Shapes  by Stuart J. Murphy. Students then visit a web site where they identify types of...

Sort this resource into the Use pile. Scholars investigate attributes of quadrilaterals and then use the results to sort and classify the shapes labeling each figure with their properties to justify the classifications.

Learners investigate triangles. In this shapes geometry instructional activity, students define and state the attributes for equilateral, scalene, and isosceles triangles. Learners locate the prefix "tri" in a variety of words and make...

In this triangles worksheet, students identify 3 triangles by the length of their sides and 3 triangles according to their internal angles.

Students are introduced to some basic concepts of geometry. They explain that the definition of a triangle is a figure with three sides, three angles, and three points. Triangles can be named by using three points in their correct sequence.

Kindergartners demonstrate their ability to identify seven different shapes by labeling each of the 28 examples on the instructional activity. Learners must be able to identify rectangles, diamonds, squares, ovals, triangles, circles,...

In this measurement lesson, learners examine the Pythagorean Theorem, perimeter, and areas of right triangles. They record their measurements and research their findings on a grid.

First angle measures, now segment lengths. High schoolers first measure segments formed by secants that intersect interior to a circle, secants that intersect exterior to a circle, and a secant and a tangent that intersect exterior to a...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

And round and round the park we go! Given a description of an amusement park with the locations of three attractions connected by walkways, learners consider what happens when additional attractions join the mix by doubling the length of...

Lead your high school class on a journey through the world of symmetry and reflections as you discuss geometric principles. Pupils differentiate between reflections and rotations, explore rotational symmetry, and investigate how to...

Pupils use clock arithmetic to find remainders. In this patterns in math lesson, students explore the relationship between clock arithmetic and remainders using a computer applet. Pupils also identify patterns in Pascal's triangle with...

Fourth graders identify and label different types of polygons in real life situations. Using a digital camera, they take pictures of polygons on the school grounds, tally the number of shapes found, and answer discussion questions.
