In this math activity, 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...

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...

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. 

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...

In this math vocabulary instructional activity, 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.

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

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

Young scholars examine the attribute of equilateral triangles. For 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...

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

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

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

Create an acute, right, or obtuse angle using a given vertex. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] In this learning module, students are presented with angles and must identify what type each is. An accompanying video demonstrates a sample problem. [2:10] A set of...

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on how to classify triangles based on angle measures.

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

This fourth-grade geometry lesson 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 whole...

[Free Registration/Login Required] This flipchart reviews right, acute and obtuse angles with students. An Activote review is included at the end.

[Free Registration/Login Required] Using this flipchart, students will be able to identify various angles based on mathematical criteria. Questions are related to right, acute, and obtuse angles.

This upper elementary and middle school lesson plan introduces the concept of acute, obtuse and right angles. Also, as the lesson proceeds vertical, adjacent, alternate interior and alternate exterior angles are explored. Plenty of...
