cylinder, pyramid) (DOK 2)

Step 2
KNOWLEDGE/CONCEPTS
REASONING
What students should KNOW (Nouns)
What students should UNDERSTAND (Mental Processes)
Recognize 2- and 3- dimensional shapes
Analyze attributes of 2- and 3- dimensional shapes
Line symmetry
Deconstructing:
Slides, turns and flips
 2- dimensional shapes have length and width
Congruent shapes
 3- dimensional shapes have length, width, and height
Deconstructing:
 attributes: a characteristic or distinctive feature—such as
shapes, size, color—of an object or given set of objects
 Parts of geometric figures: faces, vertices, sides, edges, lines,
etc.
 Line symmetry: an object has line symmetry if it can be divided
in half by one or more lines of symmetry
 sliding/translating: a transformation that involves sliding a
figure a given distance in a given direction
 turning/rotating: a transformation that involves turning a figure
at a given angle and in a given direction around a point
 Flipping/reflecting: a transformation creating a mirror image of
a figure on the opposite side of a line
 Congruent-objects that have the same shape and size

Step 3 - Big Ideas
Last Updated February 18, 2016
Shapes can be symmetrical.
Shapes have attributes and parts.
Shapes can be 2- and 3- dimensional.
Shapes stay the same when they slide and turn.
