For this math worksheet, students measure the different angles for the six problems. They use a protractor and also estimate the solutions.

For this polygons worksheet, students name the 6 different colored shapes, choose any 3 polygons to draw and color on a grid, while adding a right angled triangle and a rhombus.

The Golden Ratio. The Divine Proportion. Yup. It's math and art blended into one colorful activity. Young artists combine colored tissue paper circles and parts of circles to create geometric patterns. As a bonus, kids get to figure out...

Students walk around the neighborhood and identify various polygons and lines in buildings, nature and other objects. They design a building using various geometric patterns, shapes and lines. Students complete a descriptive writing of...

The Common Core is intended to help all children meet high academic standards. Here is a Common Core designed lesson that is intended for learners with communication or language difficulties. The lesson is written in a narrative style...

Students study West Virginia quilts. In this mathematics activity, students use symmetry, geometric shapes, and patterns to create their own quilt square.

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Students explore the global grid system. In this globe lesson, students identify latitude and longitude lines and how these can tell the coordinates of any place. They use the Internet to find the exact coordinates for their town. 

In this mathematical related worksheet, students explore and analyze thirteen key terms associated with geometry in a word search puzzle.

In this math vocabulary worksheet, students choose which multiple choice answer best defines twenty-five mathematical terms. Students place their answers on the lines provided.

In this geometry review game worksheet, students use the provided game cards and calling cards to play a Bingo-like game. Students learn geometric terms while playing a group game.

Students investigate geometric shapes. In this geometry lesson plan, students read the book The Greedy Triangle and define the shapes mentioned in the book. Students make the shapes by using their bodies.

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

Students examine the attribute of equilateral triangles. In this equilateral triangle lesson, students examine a number of paper triangles to determine how they are classified. They determine how triangles are depicted in Navajo rugs.

In this geometry worksheet, students look at a picture of downtown landmarks and identify different shapes, lines, and more. Students identify 18 items.

Students identify geometrical shapes displayed in photographs of everyday objects in a metropolitan setting.

Watch and learn how to classify angles then test your knowledge.

Brush up on your math skills pertaining to types of angles then try some practice problems to test your understanding.

This fourth-grade geometry lesson plan teaches the definitions for a line, ray, angle, acute angle, right angle, and obtuse angle. We also study how the size of the angle is ONLY determined by how much it has "opened" as compared to the...

In this lesson, young scholars will explore straight, right, acute, and obtuse angles. Students will go on a scavenger hunt throughout the school to search for examples of these types of angles. The young scholars will use digital...

In this instructional activity young scholars will learn what determines whether an angle is acute, obtuse or a right angle.
