Pupils circumscribe a circle about a triangle. They construct a triangle using Cabri Jr and then circumscribe it. They then use knowledge of perpendicular bisectors and circumcenters to locate the center of the circle and then...

Students visit a local lake refuge and identify shapes they find in nature. They take pictures of the various shapes and use KidPix to draw shapes around the shapes in the pictures. They watch a slideshow of all the shapes found by their...

Students listen to the book Mouse Shapes and identify the shapes in the book as it is being read. In this shapes lesson, students identify the shapes in the book, and then play with cut out shapes that they can hold in their hands.

High schoolers explore the concept of circles as they construct a circle using a program such as Cabri Jr. Learners construct a chord and a diameter that are perpendicular, then measure the bisected chord and notice that both sides of...

In this geometry worksheet, students choose the multiple choice answer to 15 questions involving several different elements of geometry.

In this geometry worksheet, 10th graders calculate the length of a chord and the distance from the center of a circle or radius. They compare diameter, chords and radius. There are 10 questions with an answer key.

Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are...

Students identify two- and three-dimensional figures and associate them with real-world objects.  In this geometry lesson, students are read The Very Hungry Caterpillar by Eric Carle and complete several activities including a chart...

First graders learn the names of geometric shapes and about African cultures. In this geometry and culture lesson, 1st graders describe real world objects and learn to name them with geometric terms such as square, circle, and triangle....

Students explore pi. In this circle measurement lesson, students define and identify radius, diameter, circumference, and perimeter. Students work in groups to measure several plastic lids and record their findings. Students compare the...

In this geometric shapes worksheet, students analyze a man made out of geometric shapes. Students answer 12 questions about what shapes make up each part of the body. Included are squares, rectangles, circles and triangles.

Students 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.

Develop young mathematicians' knowledge of two- and three-dimensional shapes with this geometry workbook. From learning about the classifications of different shapes and figures to calculating their area, perimeter, and volume, this...

Add a sense of excitement to your math class with this race across the country. Using their knowledge of all things circular, young mathematicians work in pairs answering a series of pi-related word problems as they hop from one city to...

Young scholars hunt for hidden geometric shapes and compare the properties of various shapes. In this geometry lesson plan, students play a game of finding squares, circles, rectangles, and ovals that have been hidden around the...

In this geometry worksheet, students solve word problems having to do with lines, angles, shapes, area, perimeter, and more. Students complete 57 problems total.

In this area worksheet, students use the perimeter or radius to determine the area of a circle. This one-page worksheet contains 8 problems. This worksheet may be produced in printed form. Answers may be viewed on-line.

Students Fulfill the requirements of Texas Standards as it relates to math and science. In this circle lesson, students identify the arcs and angles of a circle as it relates to Pi. They solve real life scenarios using space as an example.

Students explore geometric shapes.  In this geometry and language development lesson, students take a walk and look for shapes in the objects outdoors.  Students match each of four individual  paper shapes they are...

First graders analyze characteristics of geometric shapes. They identify, describe, and create simple geometric figures. They analyze characteristics of geometric shapes and determine the defining attributes of a circle,...

For this circle worksheet, students find the area and circumference of circles and compare their size using percents. Students determine the are of composite figures made of circles and rectangles. This one-page worksheet contains six...

Students identify attributes in real-life objects and models of solids and connect these attributes to characteristics of shapes such as circles, triangles, squares, and other rectangles. They discuss the ability of the object to roll,...

Students match the following 10 shapes by drawing a line from their names to their pictures: circle, square, rectangle, cylinder, cube, sphere, oval, triangle, octagon and hexagon. This geometry worksheet provides excellent practice for...

Students identify attributes of different geometric shapes. In this geometry lesson, students view a  PowerPoint presentation on shapes and use attribute blocks to examine the corners and edges of each shape. Students work together...
