Shape shifters recognize characteristics of polygons. Embracing language arts skills in addition to math, they use a thesaurus to pinpoint specific attributes of a set of polygons. They also participate in a 21-question guessing game...

Young scholars work in groups to research clocks and practice telling time. In this telling time lesson, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles using a...

Students identify polygons.  In this polygon people lesson, students draw required shapes and construct a polygon person.  They identify each shape and its characteristics.  The lesson may be extended by allowing students...

Learners classify triangles and make connections regarding angle measurements and attributes of acute, right, and obtuse triangles. They listen to teacher define and explain triangles. Everyone imagines a place where a broken wing for a...

Ninth graders identify and describe in their own language, the following 2-dimensional shapes: square, circle, box, pentagon; classify objects by shape attributes. They then list a number of properties that distinguish squares from...

Fifth graders inquire as to why scientists use observable characteristics, how they sort the characteristics, and why they do so. They write journal entries to be used throughout this unit.

Students investigate what a fossil is and how it came to be.  In this fossil lesson, students examine pictures of skeletons and identify characteristics that can and cannot be determined by a fossil.  Students complete diagrams...

Help your learners examine triangles. Pupils explore the different sizes and measurements of triangles. They discover triangles can be isosceles or scalene, and examine the attributes of triangles. Here is the website where you can...

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Not all structures take the shape of a polygon. The 21st lesson in a series of 29 shows young mathematicians they can create polygons out of composite shapes. Once they deconstruct the structures, they find the area of the composite figure.

All disciplines use data! A seven-lesson unit teaches learners the basics of analyzing all types of data. The unit begins with a study of the shape of data displays and the analysis of a normal distribution. Later lessons discuss the...

How do you know you know? Prove it! The guide goes through several examples and includes a link to a video to teach learners how to work through coordinate proofs. The goal is to prove that different shapes are indeed that shape. 

Discover how to analyze architecture from a geometric standpoint. The fourth installment of an 11-part unit on architecture first provides a presentation on axis, balance, basic form, formal, pattern, proportion, symmetry, and tripartite...

How has culture shaped you? Middle and high schoolers examine different aspects of one's culture, including religious beliefs, social customs, and family traditions, and discuss the ways that their personalities have been formed by these...

Which image represents one half? Answer the question surrounding four shapes, some of which represent one half and others representing a different amount. The last two questions ask learners to explain why some shapes represent one half...

Learners examine objects and find their volumes using geometric formulas in the 21st installment of this 25-part module. Objects take the shape of truncated cones and pyramids, and individuals apply concepts of similar triangles to find...

Display data over a larger interval. The fourth segment in a 22-part unit introduces histograms and plotting data within intervals to the class. Pupils create frequency tables with predefined intervals to build histograms. They describe...

It's test time! Determine your class's understanding of the topics of volume and cross sections with a thorough assessment on volume, area, and geometric shapes.

Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this lesson. They make a set of tangrams and use them to compute area. They use...

When your life science class is learning about the eye and how it works, you can add this activity as a demonstration of how the retina holds an afterimage. After staring at a red, green, or blue bird shape, pupils glance at a cage and...

See how art can communicate the idea of working together with your class. They will view art and describe space, color, shape, and lines in art. Then they will overlap in their art to show a sense of space. In the end, they will be able...

Identify shapes based on their attributes. Second graders are tasked to color triangles, quadrilaterals, pentagons, and hexagons specific colors. The one thing these shapes have in common? They are all polygons.
