Teach your mathematicians how to identify different polygons based on their diagonals. Relating quadrilaterals to the different number of diagonals formed, young scholars use the TI to create a visual of their shape.

Students find the diagonals of the quadrilaterals. In this geometry lesson, students identify and use properties of quadrilaterals. They define different parts of a quadrilateral shape.

Students find the length of diagonals.  In this Pythagorean theorem instructional activity, students use the Pythagorean theorem to determine the length of diagonals. 

Students discover the mathematical way to find the dimensions of a diagonal. Using this process, they complete a worksheet in which they identify the relationships between different degree triangles. They review their answers and are...

Seven activities make up a collection of supplemental materials to reinforce graphing on a coordinate plane. Worksheet objectives include plotting coordinates within single and four quadrants, measuring straight and...

Upper graders explore the Fibonacci sequence. They examine the characteristics of the Fibonacci sequence, list the properties of the sequence and determine how it connects to Pythagorean Triples. Related thinking questions are included.

Students identify the number of diagonals for each polygon. In this geometry lesson, students identify the polygons based on their diagonals and the way it intersect. They create visuals using the navigator to see the changes in the shapes.

Students identify the properties of different polygons. In this geometry lesson, students find the slope of a line and calculate the distance between two lines. They differentiate between similar and congruent polygons.

Math can be magical with exercises such as this! Prealgebrarians produce answers for nine linear equations. Each answer is placed into a square. If all answers are correct, the square will end up Sudoku-style: numbers in each row,...

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

Acute angle, line of symmetry, and vertex are a few terms you'll find in a set of 90 flashcards designed to reinforce math vocabulary. Included in the set are two types of cards; a word card printed in bold font, and a...

Students investigate the surface area and volume of the Luxor Hotel in Las Vegas. They calculate the slant height, lateral edge, and diagonal length of the base. Using this information, students explore other areas of the hotel, such as...

In this math learning exercise, students check to see if two triangles are right triangles by using the Pythagorean theorem. When given two sides of a right triangle, students find the third side. They use the Pythagorean theorem to find...

Students identify lines in everyday images.  In this art analysis lesson, students practice drawing diagonal, vertical and horizontal lines on pieces of chart paper.  Students examine a page from a magazine and identify the...

Rhombuses, rectangles and squares are have special properties. In this lesson, young geometers investigate and make conjectures about diagonals, angles, and parallel lines of parallelograms. 

Fifth graders identify, describe, and classify lines, line segments, rays, and angles. When given a diagram of a line, they classify the line as perpendicular, parallel, intersecting, vertical, horizontal, and/or diagonal.

Students demonstrate the ability to draw vertical, horizontal, and diagonal lines, recognize the difference between inside and outside, and create a picture of themselves.

For this math worksheet, middle schoolers find the area of the triangles, the perimeter of the irregular shape, and the diagonal of the cube.

Middle schoolers collect, organize, and analyze data while studying the Pythagorean Theorem, measure length and width of several rectangular objects, and compare the measured results to the calculated results.

Observe different types of lines and apply skills to create posters demonstrating line directions. Discern the four different types of lines and the ambience each creates in a room. In groups, explain each line poster.

Students create interior designs using white paper and black ink. In the process, they incorporate all four line techniques - horizontal, vertical, curved, and diagonal. While the designs do not need to be tangible representations of...

Students identify the different properties of quadrilaterals. For this geometry-lesson, students define parallel sides and diagonals of polygons as they compare to a quadrilateral. They identify the methods to find the angles in a...

Students solve problems using smaller steps. In this geometry lesson, students find the diagonals of rectangles and the area of the annulus between two circles. They are given the starting point and the radius.

Did you know one half of a rectangle be represented in more than one way? Young mathematicians choose the rectangles that represents one half with an instructive worksheet.
