Number Sense
|
1.1 Count, read, and write whole
numbers to 1,000 and identify the place value
for each digit.
For Students:
Reading Numbers
Practice
|
1.2 Use words, models, and
expanded forms (e.g., 45 = 4 tens + 5) to
represent numbers (to 1,000).
|
1.3 Order and compare whole
numbers to 1,000 by using the symbols <, =, >.

2.1 Understand and use the
inverse relationship between addition and
subtraction (e.g., an opposite number sentence
for 8 + 6 = 14 is 14 - 6 = 8) to solve problems
and check solutions.

2.2 Find the sum or difference of
two whole numbers up to three digits long.
|
2.3 Use mental arithmetic to find
the sum or difference of two two-digit numbers.
|
3.1 Use repeated addition,
arrays, and counting by multiples to do
multiplication.
|
3.2 Use repeated subtraction,
equal sharing, and forming equal groups with
remainders to do division.
|
3.3 Know the multiplication
tables of 2s, 5s, and 10s (to "times 10") and
commit them to memory.
|
4.1 Recognize, name, and compare
unit fractions from 1/12 to 1/2.
|
4.2 Recognize fractions of a
whole and parts of a group (e.g., one-fourth of
a pie, two-thirds of 15 balls).
|
4.3 Know that when all fractional
parts are included, such as four-fourths, the
result is equal to the whole and to one.
|
5.1 Solve problems using
combinations of coins and bills
|
5.2 Know and use the decimal
notation and the dollar and cent symbols for
money.
|
|
6.1 Recognize when an estimate is
reasonable in measurements (e.g., closest
inch). |
Algebra and Functions
|
1.1 Use the commutative and
associative rules to simplify mental
calculations and to check results.
|
1.2 Relate problem situations to
number sentences involving addition and
subtraction.
|
1.3 Solve addition and
subtraction problems by using data from simple
charts, picture graphs, and number sentences.
|
Measurement and Geometry
|
1.1 Measure the length of objects
by iterating (repeating) a nonstandard or
standard unit.
|
1.2 Use different units to
measure the same object and predict whether the
measure will be greater or smaller when a
different unit is used.
|
1.3 Measure the length of an
object to the nearest inch and/ or centimeter.
|
1.4 Tell time to the nearest
quarter hour and know relationships of time
(e.g., minutes in an hour, days in a month,
weeks in a year).
|
1.5 Determine the duration of
intervals of time in hours (e.g., 11:00 a.m. to
4:00 p.m.).
|
2.1 Describe and classify plane
and solid geometric shapes (e.g., circle,
triangle, square, rectangle, sphere, pyramid,
cube, rectangular prism) according to the number
and shape of faces, edges, and vertices.
|
2.2 Put shapes together and take
them apart to form other shapes (e.g., two
congruent right triangles can be arranged to
form a rectangle).
|
|
Statistics, Data Analysis, and
Probability
1.1 Record numerical data in
systematic ways, keeping track of what has been
counted.
1.2 Represent the same data set in more than one
way (e.g., bar graphs and charts with tallies).
For Students:
Make your own
graph online
1.3 Identify features of data sets (range and
mode).
1.4 Ask and answer simple questions related to
data representations.
2.1 Recognize, describe, and
extend patterns and determine a next term in
linear patterns (e.g., 4, 8, 12 ...; the number
of ears on one horse, two horses, three horses,
four horses).
2.2 Solve problems involving simple number
patterns.

Mathematical Reasoning
1.1 Determine the approach,
materials, and strategies to be used.
1.2 Use tools, such as manipulatives or
sketches, to model problems.
2.1 Defend the reasoning used and
justify the procedures selected.
2.2 Make precise calculations and check the
validity of the results in the context of the
problem. 3.0 Students note connections
between one problem and another. |
