There's more to a quilt than just a pretty pattern—there's geometry! Explore angle classification using an artistic approach to show your class that quilt designs are really just intricate geometric patterns. Here, scholars create a...

Acute or obtuse? Seems right to me! As scholars explore the simulation, they investigate angle measures. Questions ask them to classify the angles using correct naming conventions.

In this classification of triangles worksheet, 10th graders identify and complete 8 different problems that include determining the measurement and perimeter of various types of triangles. First, they color all right, acute, and obtuse...

Your learners practice the foundations of measuring two-dimensional angles. As well as the explanation of how to measure angles and their classifications, learners have plenty of practice problems on this worksheet.

Students use a protractor to measure angles. They classify angles by type: right angle, acute angles, and obtuse angles. Students build and draw right, acute, and obtuse angles. They discuss how do people in various professions use...

Don't be obtuse, this geometry unit is the just the right resource for educating the acute young minds in your class. From classifying and measuring angles, to determining the congruence of shapes, this...

Learners study acute triangles. They measure angles using a protractor, then classify the triangles as either right, obtuse, or acute. Everyone creates a design for a Navajo rug using only acute triangles.

Is that a right triangle or a wrong triangle? Young mathematicians look at eleven different shapes and use a measuring tool of their choice to determine which triangles have right angles. Consider cutting out sets of the shapes to...

Learners sharpen their classification of angles skill with a simple angles worksheet that starts with unlabeled angles and ends with specific angle measures to classify.

Learners examine a figure made up of different types of triangles and then determine whether each triangle is right, acute, or obtuse. Next, they color each type of triangle a different color. Finally, pupils answer three fill in the...

Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

Students review what they comprehend about angles. They name the differnt types of angles and define them. Students use their protractors to answer questions, the teacher walks around to look at the positioning of the protractors. ...

The interactive activity featured here calls for the use of a Smartboard for sorting and classifying shapes. Then, pupils discuss the rules they followed for sorting their shapes, particularly focusing on the properties of angles. While...

This presentation shows how triangles are classified by angle measurement and length of sides.  It reviews isosceles, scalene, obtuse, right, and acute classifications and includes questions for students to classify some of the...

After reviewing characteristics of seven types of triangles, young geometers discover how to find the missing angle of a triangle. Then, they practice identifying triangles, find missing angles, and find missing side lengths of...

In this flow chart worksheet, learners learn to use flow charts for classification of numbers, geometric shapes and animals. Students follow the directions and fill out flow charts to work out 20 answers. This is an online activity that...

In this math worksheet, students collaborate with a "study buddy" or "coach" to learn whether an angle is acute, obtuse or right. Students follow the directions to go through the process of deciding what classification an angle has....

In this triangle constructing and classifying instructional activity, learners read through a tutorial on triangles and angles. Then, students complete 17 exercises in which they answer questions about angles and triangles. By clicking...

In this angles instructional activity, students solve 20 problems pertaining to angle measurement and classification. This page is intended to be an online activity, but can be completed on paper.

In this quadrilaterals worksheet, students calculate the measure of angles in five parallelograms, name a quadrilateral, and find values of given variables in three diagrams.  The solutions are provided.

In this math worksheet, pupils analyze an informative chart about the measurement and angles of equilateral, isosceles and scalene triangles. Students then answer 5 questions about classifying triangles.

Young math whizzes solve four problems in which a triangle with labeled angle measurements is analyzed. They mark if each triangle is acute, right, or obtuse.

Excellent lesson! Anne Linehane's geometry story, The Greedy Triangle, offers an opportunity to practice forming various types of polygons with your learners. Using elastic bands (or Chinese jump ropes),...
