Students develop an understanding and enjoyment of math concepts and cultural awareness by working with tangrams.

Second graders and teachers identify geometric vocabulary word by searching a geometry website. They create a Quilt Word Wall using the geometry words.

Fourth graders discuss the various attributes of quadrilaterals. In groups, they use the attributes to sort quadrilaterals into different classes and a hierarchy. They review the new vocabulary and attributes with a partner to end the...

Students explore about triangles and their relationship to the worlld around them. They are able to identify triangular shapes in their environment. Students are able to communicate to one another their understanding of triangles outside...

Students define the terms polygon and perimeter to begin the lesson. Using a calculator, they practice determining the perimeter of various symbols in a painting. They discuss how geometry and art are related to one another.

Students examine geometric shapes. In this geometric shape lesson plan, students examine how geometric shapes flip, turn, and slide to create a pattern. Students analyze the role that quilts played in helping slaves escape to freedom. ...

Learners investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)

Students use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson.

In this shapes worksheet, 2nd graders observe different basic shapes. Students observe 6 basic shapes including a square, triangle, hexagon, trapezoid, parallelogram, and pentagon.

In this proportion worksheet, students compare two proportionate shapes and find the length of the "x" side. There are four pairs of shapes. Shapes include triangle, rectangle, parallelogram and a trapezoid.

In this tangram worksheet, students trace the tangram pieces and cut them out to solve the five problems. Students make shapes with the tangram pieces.

Ninth graders explore a variety of geometry and science concept while making an origami frog. The fold paper into the shape of a frog and conduct measurement activities including frog leaps.

Students examine new shape possibilities by combining two and four triangles using manipulatives.

Students examine the relationship between circumference and diameter and how to use the formula to find the area of a circle.  In this circle lesson plan students divide into groups and complete an activity. 

Third graders represent fractions as part of a whole. In this fractions lesson, 3rd graders use manipulatives to show how a fraction is a part of a whole. This lesson includes individual practice and an assessment instead of direct...

Third graders become more familiar with various geometric shapes by completing the games and activities in this lesson. They keep track of the number of each shape they use in each of the three ways.

Students create their own Chinese tangrams using in-class direction and prior knowledge in this two-day lesson for the early elementary classroom. Chinese toys are also explored.

Fifth graders listen to "Grandfather Tang's Story" and use tangram pieces to create animals described by the main character.

Students use this problem to develop spatial skills. As the students handle the shapes and join them together they strengthen their understanding of the attributes of shapes. This lesson also gives students the opportunity to make up...

In this proportions and similar polygons worksheet, students solve the problems that use proportions, rations, fractions, and similar polygons.

Fourth graders identify and describe lines, shapes, and solids using formal geometric language. They use Inspiration to create a graphic organizer and outline of polygons.

Seventh graders organize a 20 x 17 room with a given set of furniture pieces. Arrangement is to be based on maximum comfort and practicality. This instructional activity is a good way to teach and reinforce the mathematical concept of area.

Fourth graders work in a group of 4 to make rectangle with a 12m length of string. They discuss its perimeter and how they would calculate its area. Then another group of 4 make another rectangle and estimate if the area would be greater...

First graders practice identifying simple geometric shapes. As a class, they discuss positional words and review the words for simple shapes and their characteristics. They work together to create their own puzzle using the shapes.
