Unit: Geometry: 2D and 3D Shapes - Coggle Diagram
Unit: Geometry: 2D and 3D Shapes
Unit Goal 2 - Students will recognize the different 2D shapes in 3D shapes.
EQ : How can shapes be composed and decomposed to create new shapes and images?
Big Idea: Shapes and be composed and decomposed.
Decomposed
How a 3D shape can be decomposed into 2D shapes
Composed
how to decompose and compose 2D shapes to makes new irregular shapes and images.
Unit Goal 1 - Students will demonstrate that they understand that shapes can be decomposed and composed into new shapes and objects.
EQ: What 2D shapes are in 3D objects (shape) we see and use regularly?
Big Idea: 3D shapes are composed of 2D shapes.
3D Shapes
cubes, prisms, cylinders, spheres, pyramids, cones
Vertices, Face, Edge
Curved face (Sphere)
Square Face (cube)
Circle face (cylander)
Faces:
How many
Their shapes
Curved or flat?
Vertices and Edges
How many
Not flat
Height, Length, Width
Does it roll, stack or slide?
Attributes
Composed of 2D shapes
2D shapes
squares, circles, rectangles, triangles
Attributes:
Straight
Curved
Symmetrical
Flat
Lines
corners
Sort 2D shapes based on attributes
What is a sorting rule?
A sorting rule tells us what is similar about all of the things in a group.
When we sort shapes, we are sorting by how many sides and corners they have. We can also sort by curved and straight lines
2D objects are seen on face of objects
Unit Goal 3: Students will be able to classify shapes based on their different attributes such as whether they are symmetrical or asymmetrical, the amount of faces they have, and or the amount of corners or vertices they have.
EQ: What are the different attributes of 2D and 3D shapes?
Big Idea: Shapes can be organized and sorted based on different attributes.
3D Shapes
not flat
length, width, height
vertices, edges, faces
2D Shapes
flat
height and width
lines and corners
