Mathematics  Grade 3


Representations and Ordering

The learner will:
Understand
place value and the baseten number system.
Use
cardinal and ordinal numbers appropriately.
Recognize
and explain the concept of odd and even numbers.
Describe
parts of a set using ½, 1/3, and ¼
Represent,
order, label and compare unit fractions using concrete materials.
Describe,
represent, order, and compare whole numbers to demonstrate an understanding
of the baseten number system.
Recognize
equivalent representations of whole numbers and generate them by composing
and decomposing numbers (expanded form).
Judge
the size of fractions using models, benchmarks and equivalent forms.
Represent,
order, label and compare familiar fractions.
Recognize
and generate equivalent forms of familiar fractions.
Explore
and discuss uses of decimals in regard to money.
Represent fractions as parts of a
set, as locations on a number line, and as divisions of whole numbers.

Computation, Operations,
Estimation, and Properties

The learner will:
Solve
twostep addition and subtraction number sentences and word problems
including regrouping.
Demonstrate the
relationship between addition and subtraction and multiplication and
division.
Explore multiplication
and division through equal grouping and equal sharing of objects.
Connect repeated
addition to multiplication.
Demonstrate fluency
with basic addition, subtraction, and multiplication facts.
Identify and use relationships between and among properties of
operations.
Apply knowledge of basic multiplication facts (010) to related
facts (e.g. 3x4=12; 30x4= 120).
Estimate sums and differences of one or twodigit numbers.
Develop and use strategies to
estimate (when appropriate) the results of wholenumber computations to
judge the reasonableness of such results.

Ratio’s, Proportions, and
Percents

The learner will:
Compare unit fractions to solve problems.
Describe the
relationship between two sets using <, >, and =.

Units, Tools, Estimations, and
Applications

The learner will:
Explain the need for using standard units for measuring.
Measure objects using the U.S. customary and metric systems.
(including length, weight, time, temperature, volume and capacity)
Perform simple unit conversion within the US system of measurement.
Tell time, and find/estimate elapsed time using an analog clock.
Count, compare, order, and find equivalent amounts of money.
Make change from a given amount using bills and coins.
Solve problems using perimeter and area with appropriate units.
Use common referents for linear
measures to make comparisons and estimates.

Representations, Patterns, and
Expressions

The learner will:
Recognize, describe, extend, and create geometric and numeric
patterns.
Describe missing units or extend numeric patterns using addition or
subtraction (in word problems and equations).
Express
mathematical relationships using equations and variables (e.g. input/
output tables).

Connections Using Tables, Graphs, and Symbols

The learner will:
Describe and compare quantitative or constant rates of change in
words, graphs, or tables.
Represent and analyze
simple patterns and operations using words, tables, and graphs.

Writing, Interpreting, and
Solving Equations

The learner will:
Apply the relationship of addition/subtraction, and
multiplication/division using fact families to solve for an unknown
quantity.
Demonstrate how to select and use an appropriate operation to solve
problems using patterns.
Solve
one step linear equations using concrete materials.

Properties of Single Figures and
Coordinate Geometry

The learner will:
Investigate and predict the results of putting together and taking
apart two and three dimensional shapes, including the use of nets.
Perform translations, reflections, and rotations with concrete
objects.
Create and complete shapes that have line symmetry.
Specify locations using a coordinate system.
Identify, draw, and build
polygons.

Relationships Between and
Among Multiple Figures

The learner will:
Differentiate between polygons and nonpolygons.
Identify parallel lines.
Identify objects that are congruent and similar.
Compare and contrast appropriate attributes of two and three
dimensional objects using appropriate vocabulary.
Decompose a three dimensional object into two
dimensional components.

Data Analysis, Statistics, and
Probability

The learner will:
Organize, make predictions, and interpret simple data (pictographs,
tallies, tables, plots, line graphs, and bar graphs).
Describe the important
features of a set of data displayed by a graph.
Determine the mode of data on a graph.
Gather data in order to create graphs.
Identify and discuss likely, unlikely, and impossible probability
of events and its degree of likelihood using certain, equally likely and
impossible.
Explain probability as a fractional part of a group to the whole
group (such as 5 chances out of 8).
Make
predictions based on results received from a preformed probability
experiment.
