This article provides an overview of icebergs' formation and characteristics and the hazards associated with icebergs.

This lesson is designed for students to develop investigational skills using observation and touch. The students will determine the characteristics they wish to use to categorize the rock samples. Because the students are working in small groups they will need to cooperate to decide on the criteria for sorting. Vocabulary words to be used include color, shape, texture, size, group and belong.

This lesson serves as a review for line, shape, color, and pattern for all students. The lesson also reinforces these concepts in english for ESL students. All students participate in speaking, writing and creating activities. Also, students are introduced to the NC Museum of Art through a virtual field trip.

This student interactive, from Illuminations, allows students to explore the conditions that guarantee uniqueness of a triangle, quadrilateral, or pentagon regardless of location or orientation. Each set of conditions results in a new congruence theorem.

In this lesson students will understand the relationship between body lines and shapes. They will participate in teacher guided improvisations exploring shapes using both axial and locomotive movement. Students will also identify shapes as they are demonstrated by other dancers.

Students develop and solidify their understanding of the concept of "perimeter" as they engage in a portion of the civil engineering task of land surveying. Specifically, they measure and calculate the perimeter of a fenced in area of "farmland," and see that this length is equivalent to the minimum required length of a fence to enclose it. Doing this for variously shaped areas confirms that the perimeter is the minimal length of fence required to enclose those shapes. Then students use the technology of a LEGO MINDSTORMS(TM) NXT robot to automate this task. After measuring the perimeter (and thus required fence length) of the "farmland," students see the NXT robot travel around this length, just as a surveyor might travel around an area during the course of surveying land or measuring for fence materials. While practicing their problem solving and measurement skills, students learn and reinforce their scientific and geometric vocabulary.

This article is about the isoperimetric theorem. It states the theorem, explains its history and uses examples and exercises to demonstrate it. The resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Students to enter and compare numeric or algebraic expressions in this interactive pan balance, from Illuminations, . They can "weigh" the expressions they want to compare by entering them on either side of the balance, allowing them to practice arithmetic and algebraic skills, as well as to investigate the concept of equivalence.

The interactive pan balance uses multiple shapes with different values, allowing students to investigate what happens as different shapes are placed on the balance. This student interactive, from Illuminations, provides an interesting environment in which students can consider the concept of equivalence.

This lesson is a duel standard math lesson combining 2nd grade knowledge of shapes as well as measurement.

Students will find a certain amount of shapes and then will place them together to measure them using standard measurement tools such as a ruler or centimeter measuring tool.

This article discusses an example of a practical use of the square root of 2 by explaining how this irrational number figures in printing two pages on one side of A series-sized paper.

This resource is from Tools4NCTeachers.In this lesson, students explore attributes of polygons in order to create 2D shapes using given attributes.  Students need some basic background knowledge of the attributes of polygons, including angles, sides, vertices, and right angles.  Remix this lesson to include sample student work... Sharing is caring :)

Students are asked to use a set of pattern blocks to compose given shapes. This task may be used for instructional or assessment purposes.

This resource is part of Tools4NCTeachers.

In this lesson, students build three-dimensional representations of shapes. They discuss attributes of their shapes, and predict if their shapes will roll, slide, or both.

Kindergartners need lots of opportunities to explore, investigate and to discuss the different properties of both two and three dimensional shapes. As students learn more geometric content, they will begin to be more sophisticated in their ways of thinking.

This lesson calls for students to compose congruent hexagons using smaller pattern block pieces. They will explain which arrangements of pattern block pieces compose a congruent hexagon, and count the number of smaller pieces that compose the "bigger" shape.

This resource is from Tools4NCTeachers.In this lesson, students are given boxes to cut apart.  As they decompose the boxes, students notice the 2-dimensional shapes used to construct their 3-dimensional boxes.  A printable student recording sheet is provided within this lesson.Remix to include pictures of student work samples. 

Composing Transformations--This is part four of a four-part e-example from Illuminations that features interactive figures that allow a user to manipulate a shape and observe its behavior under a particular transformation or composition of transformations. In this part, Composing Transformations, the users are challenged to compose equivalent transformations in two different ways. e-Math Investigations are selected e-examples from the electronic version of the Principles and Standards for School Mathematics (PSSM). Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math Investigations.

In this lesson, students will read the book The Bears' Picnic by Stan and Jan Berenstain. As the book is read, a list should be compiled of the things the bears took on the picnic. The items on the list can then be grouped according to physical characteristics.
