First graders find angles in their classroom. For this geometric figures lesson, 1st graders identify, describe and classify angles they see in their world. Students create pictures that contain angles and display them in the room.

In this sum of interior angles worksheet, 10th graders solve 10 different problems that are related to determining the sum of various interior angles in figures. First, they determine the sum of the interior angles of a dodecagon. Then,...

Students classify angles. In this angles lesson plan, students explore the characteristics of angles, triangles, quadrilaterals and circles. They identify polygons and sing a classifying angles song. Students participate in a...

For this complementary and supplementary angles worksheet, 10th graders solve and complete 23 various types of problems. First, they supply a reason to justify each statement in the given sequences. Then, students find the measure of...

In this shapes activity, learners identify and name 6 different shapes by utilizing a binary tree (flow chart) to answer questions and guide them to their appropriate answers.

Challenge math scholars with polygon word problems that require logical reasoning. They answer two word problems about geometric shapes and their arrangement in a column based on clues given. Next, learners draw a robot made of...

Seventh graders participate in a instructional activity that is focused upon the concepts of classifying different angles and triangles. They practice classifying triangles according to its kind that includes types of angles, congruence,...

Use this activity for a basic review of angles. While the activities discussed are outlined, there are no materials provided to make implementation possible. When using this resource, it is necessary to create worksheets and other...

There are five shapes for scholars to identify: rectangle, circle, square, trapezoid, and triangle. Although there isn't much here, consider projecting this as an all-class warm up. Ask kids to verbalize attributes of each...

What type of corners does this shape have? Young geometers examine 12 shapes, circling the square corners in each if they have any. There are two examples demonstrating this concept, but be sure scholars understand the difference between...

Young scholars identify 3-D geometric shapes through different pieces of artwork. They examine and identify segments and angles. Students act out shapes and create a piece of artwork. Additional cross curriculum activities are listed.

Help your class identify right triangles using this resource. This series of slides involves pictures of clocks with hands forming right angles. It's an interesting way to introduce this topic.

Learners use an on-line worksheet to experiment with patterns of tessellations in regular polygons. As students observe different shapes in the "Tessellate" Activity they complete a data table and practice making predictions for...

Geometry is full of shapes, figures, and corresponding things here and there. The guide shares all of the key pieces of geometric information in a nicely color-coded and labeled sheet. 

Sixth graders identify, compare and interpret the characteristics of polygons and angles in order to meet spatial sense, geometry and measurement standards. They also sort shapes into three categories, polygons (regular and irregular)...

In this polygon instructional activity, students find the sum of the interior angles of a polygon. They determine the perimeter of equilateral figures, identify concave and convex figures and explore the characteristics of equilateral,...

Which triangles are congruent? There are two sets of triangles here for scholars to examine in order to determine which of them are congruent. They use an example and explanatory introduction to guide them through this process. The first...

This slide-show is packed with information relating to a variety of mathematical concepts. Intended as an accompaniment to a full unit, this resource provides definitions, explanations, and opportunities for learners to practice their...

In this triangles worksheet, 10th graders solve and complete 10 different problems that include applying the Triangle Inequality Theorem. First, they use the illustrated triangles and the data table to test the theorem. Then, students...

Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

Why are there so many different types of triangles? Be that as it may, beginning geometers need to understand the differences between equilateral, isosceles, scalene, and right triangles, and they get a visual approach with this...

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

This can be used as a critical thinking exercise in congruence or as a teaching tool when first introducing the concept. Four octagons are arranged in such a way that a square is formed in the middle. With this information, geometry...

Students measure angles using a plane table kit. In this geometry lesson, students use trigonometric identities to find the values of the length of a football field.
