Building
upon Knowledge and skills gained in preceding
grades,
by the end of Grade 2, students will:
Standard 4.2
(Geometry
and Measurement) All students will develop
spatial sense and the ability to use geometric
properties, relationships, and measurement
to model, describe and analyze phenomena.
Standard 4.2.K.A
Geometric
Properties
Standard 4.2.K.A.1
Identify
and describe spatial relationships among objects
in space and their relative shapes and sizes.
· Inside/outside, left/right, above/below,
between
· Smaller/larger/same size, wider/ narrower,
longer/shorter
· Congruence (i.e., same size and shape)
Standard 4.2.K.A.2
Use
concrete objects, drawings, and computer graphics
to identify, classify, and describe standard
three-dimensional and two-dimensional shapes.
· Vertex, edge, face, side
· 3D figures – cube, rectangular
prism, sphere, cone, cylinder,
and pyramid
· 2D figures – square, rectangle,
circle, triangle
· Relationships between three- and two-dimensional
shapes (i.e., the face of a 3D
shape is a 2D shape)
Standard 4.2.K.A.3
Describe,
identify and create instances of line symmetry.
Standard 4.2.K.A.4
Recognize,
describe, extend and create designs and patterns
with geometric objects of different shapes and
colors.
Standard 4.2.K.B
Transforming
Shapes
Standard 4.2.K.B.1
Use
simple shapes to maKe designs, patterns, and
pictures.
Standard 4.2.K.B.2
Combine and subdivide simple shapes to make
other shapes.
Standard 4.2.K.C
Coordinate
Geometry
Standard 4.2.K.C.1
Give
and follow directions for getting from one point
to another on a map or grid.
Standard 4.2.K.D
Units
of Measurement
Standard 4.2.K.D.1
Directly compare and order objects according
to measurable attributes.
· Attributes – length, weight,
capacity, time, temperature
Standard 4.2.K.D.2
Recognize the need for a uniform unit of measure.
Standard 4.2.K.D.3
Select and use appropriate standard and non-standard
units of measure and standard measurement tools
to solve real-life problems.
· Length – inch, foot, yard, centimeter,
meter
· Weight – pound, gram, Kilogram
· Capacity – pint, quart, liter
· Time – second, minute, hour,
day, weeK, month, year
· Temperature – degrees Celsius,
degrees Fahrenheit
Standard 4.2.K.D.4
Estimate
measures.
Standard 4.2.K.E
Measuring
Geometric Objects
Standard 4.2.K.E.1
Directly
measure the perimeter of simple two-dimensional
shapes.
Standard 4.2.K.E.2
Directly measure the area of simple two-dimensional
shapes by covering them with squares.
