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 4.2.2.A
Geometric
Properties
Standard 4.2.2.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 4.2.2.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 4.2.2.A.3
Describe,
identify and create instances of line symmetry.
Standard 4.2.2.A.4
Recognize,
describe, extend and create designs and patterns
with geometric objects of different shapes
and colors.
Standard 4.2.2.B
Transforming
Shapes
Standard 4.2.2.B.1
Use
simple shapes to maKe designs, patterns,
and pictures.
Standard 4.2.2.B.2
Combine
and subdivide simple shapes to make other
shapes.
Standard 4.2.2.C
Coordinate
Geometry
Standard 4.2.2.C.1
Give
and follow directions for getting from one
point to another on a map or grid.
Standard 4.2.2.D
Units
of Measurement
Standard 4.2.2.D.1
Directly
compare and order objects according to measurable
attributes.
· Attributes – length, weight, capacity, time, temperature
Standard 4.2.2.D.2
Recognize
the need for a uniform unit of measure.
Standard 4.2.2.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 4.2.2.D.4
Estimate
measures.
Standard 4.2.2.E
Measuring
Geometric Objects
Standard 4.2.2.E.1
Directly
measure the perimeter of simple two-dimensional
shapes.
Standard 4.2.2.E.2
Directly
measure the area of simple two-dimensional
shapes by covering them with squares.
