Problem solving
New York State Education Department Learning Standard for Mathematics
Students will understand the concepts of and become proficient with the skills of mathematics; communicate and reason
mathematically; become problem solvers by using appropriate tools and strategies through the integrated study of number sense and
operations, algebra, geometry, measurement, and statistics and probability.
Content Strands
Strand 1:
Number Sense
and Operations
Definition
Example
Students will understand numbers, multiple ways of representing numbers, 1. Verbally count by 1’s to 20.
relationships among numbers, and number systems; understand meanings 2. Solve proportions using equivalent fractions.
of operations and procedures, and how they relate to one another; compute
accurately and make reasonable estimates.
Strand 2:
Algebra
Students will represent and analyze algebraically a wide variety of
problem solving situations; perform algebraic procedures accurately;
recognize, use, and represent patterns, relations, and functions
algebraically.
1. Use a variety of manipulative materials to
create patterns using attributes of color, size,
or shape.
2. Solve simple one-step equations using basic
whole number facts.
Strand 3:
Geometry
Students will use visualization and spatial reasoning to analyze
characteristics and properties of geometric shapes; identify and justify
geometric relationships, formally and informally; apply transformations
and symmetry to analyze problem solving situations; apply coordinate
geometry to analyze problem solving situations.
1. Identify and appropriately name twodimensional shapes: circle, square,
rectangle, and triangle (both regular and
irregular).
2. Classify angles as acute, obtuse, right and
straight.
Strand 4:
Measurement
Students will determine what can be measured and how, using appropriate
methods and formulas; use units to give meaning to measurements;
understand that all measurement contains error and be able to determine
its significance; develop strategies for estimating measurements.
1. Compare the length of two objects by
representing each length with string or a
paper strip.
2. Identify radius, diameter, chords, and central
angles of a circle.
Strand 5:
Statistics
and Probability
Students will collect, organize, display, and analyze data; make
predictions that are based upon data analysis; understand and apply
concepts of probability.
1. Display data in bar graphs using concrete
objects with intervals of one.
2. Calculate the mean for a given set of data
and use it to describe a set of data.
