- MAFS.K.G.2.4: Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/“corners”) and other attributes (e.g., having sides of equal length).
- MAFS.K.G.2.5: Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.
- MAFS.K.G.2.6: Compose simple shapes to form larger shapes. For example, “Can you
join these two triangles with full sides touching to make a rectangle?”

Standard 2: Analyze, compare, create, and compose shapes. (Supporting Cluster) Archived
Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
Cluster Standards
This cluster includes the following benchmarks.

Original Student Tutorials
- Sorting Shapes: Learn to sort and identify two-dimensional and three-dimensional shapes in this carnival-themed interactive tutorial.
- The Search for Shapes: Recognizing Rectangles and Squares: 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.
This is part of a series on the defining attributes of shapes. Click the links below.

- The Search for Shapes: Recognizing Rectangles and Squares"
- The Shape Factory with Robbie the Robot: Learn to combine simple shapes to compose larger shapes with Robbie the Robot in this interactive tutorial.
- Building Shapes With Becca: Help Becca identify and build shapes that you see in the world around you as you complete this interactive tutorial.
- Briana's Shape Playground: Learn how to identify the similarities and differences in the number of sides of two-dimensional shapes in this interactive tutorial.
Formative Assessments
- Hexagonal Tiles: Students examine a picture of hexagonal tiles and draw a model of a tile.
- Modeling the Shape of the Door: Students draw the outline of the door.
- Model the Shapes: Students look at two photographs taken at a school and choose a shape from one of the photographs to model or draw.
- How Are These Shapes Alike?: Students compare and contrast two shapes based on their attributes.
- Draw a Triangle: Students draw a triangle and explain their reasoning in drawing the shape.
- Cubes and Prisms: Students compare a cube to a rectangular prism and discuss the similarities and differences.
- Compose a Rectangle: Students join two right triangles together to compose a rectangle.
- Compose a Hexagon: Students use triangles to compose a hexagon.
- Can You Make a Rectangle?: Students are asked to make a rectangle using only squares.
- Compare Rectangles and Triangles: Students compare a triangle to a rectangle based on attributes of these figures.
- Compare Hexagons: Students compare two hexagons and describe how they are alike and how they are different.
- Compose a Square: Students join small squares together to compose a larger square and then justify the new shape.
Lesson Plans
- Creating Shapes in Our World: 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.
- Understanding Polygons: 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.
- Eating Shapes (Exploring 3D Shapes): 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!
- Hide and Seek those Shapes: 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.
- ShapeBot: 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".
- Shape Creator: 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.
- Shape Up!: 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.
