Indicator

  

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
