10/24 We continue to practice subtraction with regrouping and estimating.
When asked to estimate or if an answer is reasonable, the students need to
round, then add or subtract to estimate. The class has been introduced to
multiplication families of 0's, 1's, and 2's. Few the next few weeks, we will
continue to practice those facts.
10/19 Throughout the next few weeks, we will continue to practice all the
skills that we have introduced in Topic 1 and Topic 2. The next area of math
that will be our main skill is subtraction.
10/3 Vocabulary quiz 10/6
Topic 1 – 5, 1 – 6, 1 - 7 Math Vocabulary
Compare – to decide if one number is greater than or less than another number
Order – to arrange numbers from least to greatest or greatest to least
Dollar sign - $ - a symbol used to indicate money
Decimal point – a dot used to separate dollars from cents in money
9/16 Today a study guide was sent home for our first math quiz.
Math Vocabulary Study Guide * Test 9/22
Topic 1 – 1 Math Vocabulary
Digit – the numbers 0,1,2,3,4,5,6,7,8,9
Place value – the value of the place a digit has in a number (example: In
the
number 4,125 – the 1 has a value of 100)
Standard form – a number written in a way that shows only the digits
(example: 4,125)
Expanded form – a number written as the sum of the value of its digits
(example: 4000 + 100 + 20 + 5)
Word form – a number written in words (example: four thousand, one hundred
twenty-five)
Place Value Form - using place value blocks to represent a number - see study
guide.
9/8 For the first few days, we will be reviewing and assessing basic
addition
and subtraction. The students will also be given a basic second grade
cumulative assessment. These assessments will not be graded, but simply
used
for information of where the students are with basic math skills. Our first
math concepts will be place value - tens, hundreds, and thousands.

The NYS Mathematics Curriculum is designed to provide students with
conceptual understanding, procedural fluency, and problem solving skills. It
contains five content strands: number sense and operations, algebra,
geometry, measurement, and probability and statistics. It also includes five
process strands: problem solving, reasoning and proof, communication,
connections, and representation. These strands are addressed at every grade
level through the study of specific mathematical concepts and skills. In 3rd
grade students review and extend their skills with addition and subtraction.
A major focus is the introduction of multiplication and division, mastery of
multiplication facts, and extensive practice with applications that require
the four basic operations. Time, money, graphs, geometry, and measurement
activities are interspersed through the year. Below are the areas of study
for Grade 3 mathematics.
Place Value and Money
� Numbers in the hundreds, place-value patterns, comparing numbers, number
patterns
� Counting money
Addition and Subtraction
� Addition properties, estimating sums, estimating differences,
overestimates and underestimates
� Adding and subtracting three-digit numbers, adding
three or more numbers, subtracting across zero
� Equality and inequality
Time, Data, and Graphs
� Time - half hour, quarter hour, minute
� Organizing data, Pictographs, Bar Graphs
Multiplication Concepts and Facts
� Arrays and multiplication
� 2, 5, 9, 10 as a factor
� Multiplying with 0 and 1
� 3, 4, 6, 7, 8 as a factor
� Patterns, practicing multiplication facts
Division Concepts and Facts
� Division as sharing, repeated subtraction
� Dividing with 2, 3, 4, 5, 6, 7, 8, 9
� Dividing with 0 and 1
� Division patterns
Geometry
� Solids and shapes
� Polygons, triangles, quadrilaterals
� Congruence, symmetry
Fractions and Measurement
� Equal parts of a whole, naming fractional parts
� Equivalent fractions, fractions on a number line, comparing and ordering
fractions
� Estimating fractional amounts, fractional parts of a set
� Length � feet, inches, yards, miles, measuring to the nearest � and � inch
� Capacity, weight
Multiplying and Dividing Larger Numbers
� Multiplication and division patterns, estimating products and quotients
� Arrays, breaking numbers apart to multiply and divide
Assessment: All students in grade 3 take the NYS Math Assessment in March.
They also take WCSD math assessments in January and June. Teacher-created
tests and performance activities are used to assess students� level of
mastery throughout the year.
