    Math Skill:  Greater Than and Less Than
    The dreaded alligator....
    ALWAYS read number sentences from LEFT to RIGHT, just as you do a book.  This will help you to understand these confusing symbols a little better.
    Examples: 
    25  >  22  --- 25 is Greater Than 22
    30  <  55  ---  30 is Less Than 55
     
     
    Math Skill:  Fact Families:
    Addition/ Subtraction
    -number sentences that go with a set of numbers
    Example:   The fact family for the numbers
    6, 7, 13
     7 + 6 = 13                 13 - 7 = 6
    6 + 7 = 13                 13 - 6 = 7
     
    **Addition and Subtraction are OPPOSITES**
    They "undo" each other!

    Place Value
    Place value is the value of a digit as determined by its position in a number, the name of the place or location of a digit in a number.

    When we write numbers, the position (or "place") of each number is important.

    In the number 327:

    • the "7" is in the Ones position, meaning just 7 (or 7 "1"s),
    • the "2" is in the Tens position meaning 2 tens (or twenty),
    • and the "3" is in the Hundreds position, meaning 3 hundreds.

    Place Value

     

    This number can also be written as:
    • three hundred twenty seven
    • 300 + 20 + 7
     
    Geometric Shapes
    Plane shapes- 2 dimensional figures (examples: square, circle, triangle, rectangle, pentagon, and hexagon)
    Solid shapes- 3 dimensional figures (examples: cylinder, cone, rectangular prism, pyramid, and cube)
