Students find triangular angles using the angle theorem. In this geometry lesson, students describe labeled triangles, use the pythagorean theorem, and rewrite information about triangles in standard form.

Set your pupils up to start on geometry by teaching them some introductory terminology. Pupils learn the terms by reading a short passage and looking at examples. They then respond to five questions related to the text.

The class gets to practice being a mathematician in ancient Greece, performing geometric application problems in the way of Eratosthenes. After following the steps of the great mathematicians, they then compare the (surprisingly...

An intersection is more than just the point where lines intersect; explain this and the meaning of the intersection to your class. The 26th segment in a 33-part series uses graphing to solve systems of equations. Pupils graph linear...

In this identifying parallel lines worksheet, young scholars discover examples of parallel lines at school, home, and outside and list them on a chart. Students write at least 10 short answers.

Learn how to spell the names of basic shapes. Ten shapes are shown, and the learner must write the correct spelling in the spaces provided to the left. There's even a bit of scaffolding provided for your youngsters, as each letter has...

Students demonstrate how to alphabetize animal names. In this word study lesson, students identify animals that live on the farm and conduct a favorite farm animal survey. Students order animal pictures in alphabetical order.

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...

Learners find the area and perimeter of regular polygons and composite figures and examine the effect on the area and perimeter of a figure if the dimensions are multiplied by a constant. The nine page worksheet contains thirty-seven...

In this pattern worksheet, students enumerate the number of objects that comes next in the sequence including triangles, blocks, and circles. There are 6 questions.

Explore shape attributes with young geometers as they sort nine shapes based on their corners. Scholars determine whether or not each shape has a square corner, drawing it in the appropriate space accordingly. They are encouraged to use...

Some shapes have square corners, and some do not. Scholars participate in a sorting activity as they determine if these 12 shapes have square corners, categorizing them based on this attribute. Encourage geometers to draw the square into...

Is it half? There are three sections to this introductory fractions learning exercise focusing on halves. First graders begin by coloring half of five basic shapes, each of which already is divided into two parts. Next, they examine four...

There's a party going on! Learners examine an image of a birthday party and answer 10 analysis questions. They employ a variety of math skills including telling time, days of the week, division, subtraction, multiplication, addition,...

Have fun with shapes! Third graders read a set of instructions and circle the shape in the description. They work on recognizing parallel sides and right sides. Use this resource as homework after your geometry lesson.

Use shapes to visualize fractions! Elementary learners color 1/2, 1/3, 1/4, 1/8, and 1/10 of various shapes. A great addition to your fractions lesson, or to introduce geometry in your math unit.

How can you tell if shapes are symmetrical? Fourth graders study 12 shapes, and draw lines down the middle of shapes that have symmetry. Once they are finished, they complete shapes that are missing their symmetrical sides. Some shapes...

Enhance your geometry lesson by working with shapes. Fourth graders follow lines of symmetry to complete ten shapes, most of them currently triangles. Have pupils color each half of their shapes to reinforce the idea of symmetry!

Practice finding the area of squares and rectangles. Complete with a grid for third graders to measure each side, this resource will be helpful. Though the shapes vary in size, they all have four sides to make measurement easy. Pupils...

Can your first graders identify a cone? What about a cube? Or a prism? Help them find the differences between these shapes with this instructional activity, which provides a word bank for three-dimensional shapes. For extra practice,...

Scholars create and perform experiments attempting to answer Buffon's Coin problem. They discover the relationships between geometry and probability, empirical and theoretical probabilities, and area of a circle and square.

Shapes are everywhere in the world around us, from rectangular doors to the circular wheels of a car. The second lesson in this series opens the eyes of young mathematicians to this wonderful world of shapes as they search the classroom,...

There's more to a quilt than just a pretty pattern—there's geometry! Explore angle classification using an artistic approach to show your class that quilt designs are really just intricate geometric patterns. Here, scholars create a...

Using a slider, scholars build triangular numbers and their associated rectangles and use the geometric display to find the pattern to determine the next triangular number. They then relate that number to the area of the rectangle to...
