Students identify missing sides and angles. For this geometry lesson, students use triangular theorems to identify the missing sides. They use the Pythagorean Theorem to find the different ratios of each side.

Young scholars practice identifying spheres, triangles, and rectangles and the difference between plane shapes and space shapes. They identify shapes in the classroom and complete activity sheets.

Students identify polygons and calculate perimeter. In this geometric shapes lesson, students complete a worksheet identifying various polygons and calculating the perimeter of triangles and quadrilaterals.

In this angle measures worksheet, students solve six word problems where they are given 6 different polygons, some of which are complex, and must determine angle measures in order to arrive at a solution.

Use this comprehensive pre-instruction assessment tool to focus your teaching where your class needs it most. Multiple choice questions assess your budding geometers' conceptual and vocabulary knowledge, but they do not solve any...

What polygon is this? Young geometers categorize shapes by circling all the quadrilaterals in a set of figures. Next, they write the names of 10 polygons using a visual guide as reference. Review the guide together before they start if...

How can learners use algebra to solve a geometry problem? Help learners create an equation that shows the relationship between the number of sides of a polygon and the sum of the interior angles. Students are asked to divide the...

A series of geometry worksheets have mathematicians constructing, dissecting, overlapping, and measuring as they analyze angles in various contexts. Learners use symmetry and reflections in a compass rose to write instructions on...

How well does your class know their shapes? This interactive shape quiz provides learners with four clues which they will use to determine identify each shape. This is an excellent way to assess how well learners know their shapes and...

Challenge your geometry class with this connect-the-dots activity! Scholars use a ruler to complete simple shapes through connecting dots in 6 shape-identification problems, and identify it from 4 choices: triangle, square, rectangle, or...

Trying to figure out the perimeter of a geometric figure? Here are a few word problems to set up algebraic equations to solve for perimeter. There are also some word problems to set up algebraic equations to solve for angles in a...

This resource provides 5 different worksheets on the topic of polygons and symmetry. These worksheets cover rotational symmetry, lines of symmetry, symmetry of regular polygons, special quadiralaterals, and polygon transformation. The...

Some of the best practice with shape identification comes from drawing the figures first-hand. Young geometers draw nine two-dimensional shapes: rectangle, circle, square, pentagon, hexagon, octagon, triangle with three equal sides,...

Explore five basic shapes- square, rectangle, triangle, circle, and stars with youngsters. They will participate in hands-on activities, draw each shape, name each shape. They also get to eat things that are in the shapes they have just...

Get to know eight shapes by name: square, rectangle, triangle, pentagon, hexagon, and octagon. Young geometers write the correct name below each of these shapes, using a word bank for guidance. Then, they draw two of the...

Sorting is a great way to familiarize learners with basic shapes in this partner activity. Pairs have sixteen shape cards with various sizes and types of triangles, rectangles, hexagons, and squares. They have four category cards in...

Inside each of these two-dimensional shapes, scholars identify the figure by writing its name. There is a word bank for them to work from, but some shape names are used multiple times. There are six identifiers they use: pentagon,...

For beginners to color, number, and shape theory, this is a great way to solidify skills. They use a key at the top to determine which color (yellow, green, purple, or blue) to shade each shape (square, triangle, circle, and rectangle,...

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.

Primary geometers create a picture using tangrams. In this geometry activity, students read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their tangram pieces.

Upper graders investigate how to find the surface area when using two-dimensional shapes. They conduct an investigation in groups while working sample problems given during class discussion with the teacher. They also review how to...

Pupils establish classifications of shapes by various properties (angles, sides, etc.). They introduce the important properties of common shapes. Students develop an awareness of the wide variety of ways the 2-D shapes can be alike.

In this recognizing characteristics of shapes worksheet, students identify characteristics of quadrilaterals, triangles, and parallelograms and determine which sets fall under the same category. Students solve four problems.

Identify and make conjecture about properties of cyclic quadrilaterals. Students use the TI Navigator to create different shapes and draw conclusions.
