A. Use place value concepts to represent whole numbers
using numerals, words and
physical models. |
1. Use place value concepts to represent, compare and
order whole
numbers using physical models, numerals and words with ones, tens, and hundreds. For
example: Recognize 10 can mean “10 ones” or a
single entity (1 ten) through physical models and trading games Restate 3-digit numerals (e.g., 243 as two
hundred forty three, 24 tens and 3 ones, or 2 hundreds and 43 ones, etc.) and
construct models to represent each |
|
|
B. Recognize, classify, compare and order whole numbers. |
1. Recognize and classify numbers as even or odd. 2. Compare numbers as greater than, less than, or equal
to. 3. Order 3 digit numbers to 999. |
|
|
C. Represent commonly used fractions using words and
physical models. F. Count using numerals and ordinal numbers. |
1. Represent fractions (halves, thirds, fourths, sixths
and eighths) using words, numerals and
physical models: Recognize that a fractional part can mean
different amounts depending on the original quantity Recognize that a fractional part of a rectangle
does not have to be shaded with contiguous parts Identify and illustrate parts of a whole and
parts of sets of
objects Compare and order physical models of halves,
thirds, and
fourths in relation to 0 and 1 Use appropriate vocabulary: numerator and
denominator |
|
|
|
D. Determine the value of a collection of coins and
dollar bills. |
1. Identify the value of money using the ¢ sign and
in decimal form when using the $
sign. |
|
E. Make change using coins for values up to one dollar. |
1. Demonstrate the ability to count money and identify
change using coins and a dollar bill. |
|
|
H. Model, represent and explain subtraction as
comparison, take- away
and part-to-whole. |
1. Model, construct and explain subtraction as
comparison, take-away and part-to-whole (e.g.,
solve missing addend problems by counting up or
subtracting, such as “I had six baseball cards, my sister gave me
more, and I now have ten. How many did she give me?” can be represented as 6 + ? = 10 or 10 – 6 = ?. |
|
|
I. Model, represent and explain multiplication as
repeated addition rectangular
arrays and skip counting. |
1. Model, construct and explain multiplication as
repeated addition,
rectangular arrays and skip counting. |
|
|
J. Model, represent and explain division as sharing
equally repeated subtraction and
rectangular arrays. |
1. Model, construct and explain division as sharing
equally, repeated
subtraction and rectangular arrays. |
|
|
K. Demonstrate fluency in addition facts with addends
through 9 and
corresponding subtractions. |
1. Model and use the commutative property for addition. 2. Demonstrate fluency in addition facts with addends
through 18 and corresponding subtractions
(e.g., 9 + 9 = 18, 18 – 9 = 9). |
|
|
|
L. Demonstrate fluency in adding and subtracting
multiples of 10 and recognize
combinations that make 10. |
1. Demonstrate the ability to add and subtract multiples
of 10. |
|
M. Add and subtract two-digit numbers with and without regrouping. |
1. Model and use the commutative property for addition. 2. Demonstrate multiple strategies for adding and subtracting 2-
or 3-digit whole numbers such as: Compatible numbers Compensatory numbers Informal use of commutative and associative
properties of addition |
