Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

Young geometers and biologists investigate the math of nature in an activity that is just the bee's knees. Participants will study the tessellations of hexagons in a beehive, along with the natural rationale behind the specific shape....

A General Certificate of Secondary Education math review has class members make basic constructions. Using a protractor and a ruler along with a compass, pupils develop drawings of triangles with given measurements. Scholars use their...

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

Students investigate the properties of triangles and parallelograms. In this geometry lesson, students calculate the formula used to find the are of a triangle and other polygons. They create a visual model to represent their findings.

In this geometry worksheet, students study 4 pictures of shapes and using the word bank, label them. Students then draw the specified shapes in four more problems.

Let's study 2-D shapes! Young mathematicians compare and classify shapes according to attributes. They evaluate shape riddles and predict the shape being described. Here is the website where you can find the...

A cross-curricular approach to prepositions includes a geometry aspect as learners label eight pictures of shapes to indicate their positioning. Each picture has two shapes, some with arrows to show which shape's location scholars are...

Students complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a quadrilateral...

Students familiarize themselves with the construct and measure menus. They demonstrate how to use the Sketchpad Calculator. They draw a triangle and construct the centroid. They shade in each of the small triangles and measure the area.

Make origami ducks with your class to reinforce geometry concepts and vocabulary; develop fine motor and visual translation skills; and enrich study of Japanese culture, the pond habitat, or migration. Create a whole group "worksheet"...

It can be so much fun to learn about new shapes! Kindergartners are shown a series of different shapes; each one is a different color, size, or orientation. They look at the shapes and discuss that no matter their color or size, a square...

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions. 

Students examine the painting "Old Man With A Gold Chain" by Rembrandt. They identify geometric shapes in the painting, measure these shapes and compare the relationships of these measurements.

In this geometry learning exercise, students examine a picture that has many hidden triangles. Students count the triangles they discover and color the picture.

Students construct triangles. For this geometry lesson, students create equilateral triangles. They also construct triangles where the sides are different. They use the lab to create and move shapes around with the Cabri program.

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

Students calculate the distance from the vertex of a triangle to the center. In this geometry lesson, students find the shortest distance between a point and the vertex of a triangle. They relate this concept of distance to the real world.

Students explore geometry by participating in a class card game. For this triangle lesson, students utilize playing cards with shapes on them which they group up and discard, similar to "Old Maid." Students complete a worksheet and...

Students calculate the measurements of the inscribed angles of a triangle. In this geometry lesson plan, students relate the hypotenuse of a right triangle and the diameter of a circle to each other. They calculate the diameter of a...

In this geometry worksheet, students answer 5 questions, finding shapes using a figure with labeled line segments running through it. A reference website is given for additional resources.

In this counting shapes worksheet, students count how many squares, rectangles, circles, and triangles they can count in the picture of a house. Students count 45 shapes total.

In this geometry worksheet, students select characteristics from a word bank that make sets of shapes fall into the same category. A reference web site for additional activities is given.

Pupils investigate inscribing a circle in a triangle. They use Cabri Jr. to draw a triangle, locate the incenter, and use the distance from the incenter to a side of the triangle to inscribe a circle. The dynamic nature of the geometry...
