The fourth-grade standards
place emphasis on multiplication and
division with whole numbers and solving
problems involving addition and subtraction
of fractions and decimals. Students
will continue to learn and use the
basic multiplication facts as they
become proficient in multiplying larger
numbers. Students also will refine
their estimation skills for computations
and measurements and investigate relationships
between and among simple two-dimensional
(plane) figures and three-dimensional
(solid) figures. Students will identify
and draw representations of points,
lines, line segments, and rays. Students
will graph points in the first quadrant
in the coordinate plane and extend
and duplicate patterns. Concrete materials
and two-dimensional representations
will be used to solve problems involving
perimeter, patterns, probability,
and equivalence of fractions and decimals.
Students will recognize a geometric
transformation, such as reflection
(flip), translation (slide), and rotation
(turn).
While learning mathematics, students
will be actively engaged, using
concrete materials and appropriate
technologies such as calculators and computers.
However, facility in the use of technology shall
not be regarded as a substitute for a student’s
understanding of quantitative concepts and relationships
or for proficiency in basic computations.
Mathematics has its own language,
and the acquisition of specialized
vocabulary and language patterns
is crucial to a student’s understanding and
appreciation of the subject. Students should
be encouraged
to use correctly the concepts, skills, symbols,
and vocabulary identified in the following set
of standards.
Problem solving has been integrated
throughout the six content strands.
The development of problem-solving
skills should be a major goal of the mathematics
program at every grade level. Instruction in
the
process of problem solving will need to be integrated
early and continuously into each student’s mathematics
education. Students must be helped to develop
a wide range of skills and strategies for solving
a variety of problem types. |

| 4.10 |
The

U.S. Customary/metric units
as appropriate, including ounces,

between units within the U.S.
Customary system (ounces and
pounds) and between units
within the metric
system (grams and kilograms);
and

of ounces and grams and pounds
and kilograms, using approximate
comparisons (1 ounce is about
28 grams, or 1 gram is about
the weight of a paper clip;
1 kilogram is a little more
than 2 pounds).
* * The intent
of this standard is for students
to make ballpark comparisons and
not to memorize conversion factors
between U.S. Customary and metric
units. |
