Cluster 2: Analyze, compare, create, and compose shapes. (Supporting Cluster)Archived

In this game, learners use clues to identify mystery shapes. Use everyday objects (like from the pantry) as the shapes. It is important for learners to be able to describe a shape with correct math vocabulary and to be able to visualize a shape in their head.

Type: Educational Game

Students examine a picture of hexagonal tiles and draw a model of a tile.

Type: Formative Assessment

Students draw the outline of the door.

Type: Formative Assessment

Students look at two photographs taken at a school and choose a shape from one of the photographs to model or draw.

Type: Formative Assessment

Students compare and contrast two shapes based on their attributes.

Type: Formative Assessment

Students draw a triangle and explain their reasoning in drawing the shape.

Type: Formative Assessment

Students compare a cube to a rectangular prism and discuss the similarities and differences.

Type: Formative Assessment

Students join two right triangles together to compose a rectangle.

Type: Formative Assessment

Students use triangles to compose a hexagon.

Type: Formative Assessment

Students are asked to make a rectangle using only squares.

Type: Formative Assessment

Students compare a triangle to a rectangle based on attributes of these figures.

Type: Formative Assessment

Students compare two hexagons and describe how they are alike and how they are different.

Type: Formative Assessment

Students join small squares together to compose a larger square and then justify the new shape.

Type: Formative Assessment

In this lesson, students will work with 3-Dimensional shapes identifying attributes of the shapes and recreating them. Students will create, identify and describe 3-Dimensional shapes as part of the assessment process.

Type: Lesson Plan

This is a simple and fun activity that is great to incorporate into your geometry unit. As you read "The Greedy Triangle" aloud, the students "create" each shape with marshmallows and pretzel sticks - as you are reading the story, they complete a sheet in which they write the name of each shape, draw the shape, and record the number of sides and vertices each shape has.

Type: Lesson Plan

This lesson is an introduction to 3-dimensional shapes. The lessons uses food to help students explore the attributes of those shapes. Then, of course, the students get to eat them!

Type: Lesson Plan

In this lesson, students will discover the names of different two-dimensional and three-dimensional shapes and their attributes through activities such as playing "Hide and Seek" with shapes and playing "Hot and Cold" to find shapes in the classroom.

Type: Lesson Plan

In this hands-on lesson, students will be challenged to demonstrate their understanding of shapes to combine smaller two-dimensional shapes to form larger composite shapes. The lesson culminates with students using triangles, rectangles, and squares to form a "robot".

Type: Lesson Plan

In this lesson, students will be taking their knowledge of two-dimensional shapes and applying it to recognizing combinations of shapes in real-world objects. They will also sketch these shapes and use them to model real-world objects.

Type: Lesson Plan

Students work together to build and identify three-dimensional shapes and their attributes.

Type: Lesson Plan

In this lesson students will compare two-dimensional shapes to other two- dimensional shapes (circle, square, triangle, and rectangle) and three-dimensional shapes to other three-dimensional shapes (cone, cylinder, sphere, cube) by differentiating them according to attributes. Students describe attributes of shapes by exploring real world objects.

Type: Lesson Plan

This is a hands-on lesson that introduces and allows students to identify and build three-dimensional figures including rectangular prisms, square pyramids, and cubes. The students will also gain an understanding of what a vertex is, and how many vertices a given shape has.

Type: Lesson Plan

Integrating mathematics and literacy allows students to develop an understanding of the place of mathematics in their world. Students are introduced to the idea of shapes through a read-aloud session with an appropriate book. They then use models to learn the names of shapes, work together and individually to locate shapes in their real-world environment, practice spelling out the names of shapes they locate, and reflect in writing on the process. This lesson provides opportunities to engage students using many different learning modalities.

Type: Lesson Plan

Learn to sort and identify two-dimensional and three-dimensional shapes in this carnival-themed interactive tutorial.

Type: Original Student Tutorial

Identify and name rectangles and squares based on their defining attributes, even if they have different sizes or positions. Join King Geo and his scout, Quad, as they search for rectangles and squares in this interactive tutorial.

Type: Original Student Tutorial

Learn to combine simple shapes to compose larger shapes with Robbie the Robot in this interactive tutorial.

Type: Original Student Tutorial

Help Becca identify and build shapes that you see in the world around you as you complete this interactive tutorial.

Type: Original Student Tutorial

Learn how to identify the similarities and differences in the number of sides of two-dimensional shapes in this interactive tutorial.

Type: Original Student Tutorial

In this activity, learners work together to make polygons with string. Learners explore making different kinds of triangles, quadrilaterals, and other polygons. Through teacher-led questioning and discussion, students can analyze and compare two dimensional shapes in different sizes and orientations, as well as similarities, differences, and attributes. (Please note: the understanding of concave & convex polygons are not part of kindergarten geometry standards.)

Type: Teaching Idea

To give students opportunities to recognize, describe, build, and explore shapes in many different contexts.

Type: Teaching Idea

This virtual manipulative allows you to create, color, enlarge, shrink, rotate, reflect, slice, and glue geometric shapes, such as: squares, triangles, rhombi, trapezoids and hexagons.

Type: Virtual Manipulative

This virtual manipulative allows you to create patches and more complex figures using the provided 2-dimensional geometric shapes.

Type: Virtual Manipulative

This virtual manipulative allows students to draw geometric shapes and then decompose and recompose them into other shapes, using slides, turns, and flips to cut and move pieces around.
