| Mathematics Content Standards Kindergarten |
| Number Sense |
| 1.0 |
Students understand the relationship between
numbers and quantities (i.e., that a set of objects has the
same number of objects in different situations regardless
of its position or arrangement):
|
| |
| 1.1 |
Compare two or more sets of objects (up to ten
objects in each group) and identify which set is equal
to, more than, or less than the other.
|
|
| |
| 1.2 |
Count, recognize, represent, name, and order a
number of objects (up to 30).
|
|
| |
| 1.3 |
Know that the larger numbers describe sets
with more objects in them than the smaller numbers
have.
|
|
| 2.0 |
Students understand and describe simple additions
and subtractions:
|
| |
| 2.1 |
Use concrete objects to determine the answers
to addition and subtraction problems (for two numbers
that are each less than 10).
|
|
| 3.0 |
Students use estimation strategies in computation
and problem solving that involve numbers that use the ones
and tens places:
|
| |
| 3.1 |
Recognize when an estimate is
reasonable
|
|
| Algebra and Functions |
| 1.0 |
Students sort and classify objects:
|
| |
| 1.1 |
Identify, sort, and classify objects by
attribute and identify objects that do not belong to a
particular group (e.g., all these balls are green,
those are red).
|
|
| Measurement and Geometry |
| 1.0 |
Students understand the concept of time and units
to measure it; they understand that objects have
properties, such as length, weight, and capacity, and that
comparisons may be made by referring to those properties:
|
| |
| 1.1 |
Compare the length, weight, and capacity of
objects by making direct comparisons with reference
objects (e.g., note which object is shorter, longer,
taller, lighter, heavier, or holds more).
|
|
| |
| 1.2 |
Demonstrate an understanding of concepts of
time (e.g., morning, afternoon, evening, today,
yesterday, tomorrow, week, year) and tools that measure
time (e.g., clock, calendar).
|
|
| |
| 1.3 |
Name the days of the week.
|
|
| |
| 1.4 |
Identify the time (to the nearest hour) of
everyday events (e.g., lunch time is 12 o'clock;
bedtime is 8 o'clock at night).
|
|
| 2.0 |
Students identify common objects in their
environment and describe the geometric features:
|
| |
| 2.1 |
Identify and describe common geometric objects
(e.g., circle, triangle, square, rectangle, cube,
sphere, cone).
|
|
| |
| 2.2 |
Compare familiar plane and solid objects by
common attributes (e.g., position, shape, size,
roundness, number of corners).
|
|
| Statistics, Data Analysis, and Probability |
| 1.0 |
Students collect information about objects and
events in their environment:
|
| |
| 1.1 |
Pose information questions; collect data; and
record the results using objects, pictures, and picture
graphs.
|
|
| |
| 1.2 |
Identify, describe, and extend simple patterns
(such as circles or triangles) by referring to their
shapes, sizes, or colors.
|
|
| Mathematical Reasoning |
| 1.0 |
Students make decisions about how to set up a
problem:
|
| |
| 1.1 |
Determine the approach, materials, and
strategies to be used.
|
|
| |
| 1.2 |
Use tools and strategies, such as
manipulatives or sketches, to model
problems.
|
|
| 2.0 |
Students solve problems in reasonable ways and
justify their reasoning:
|
| |
| 2.1 |
Explain the reasoning used with concrete
objects and/ or pictorial representations.
|
|
| |
| 2.2 |
Make precise calculations and check the
validity of the results in the context of the
problem.
