Students will know…                                                                     K
    Numerator: the term above the line in a fraction. The numerator tells how many parts are being talked
     about or considered.
    Denominator: the number below the line in a fraction. The denominator indicates what kind or size of
     parts the numerator counts.
    Decimal Point: a period separating the ones and tenths.
    Decimal: a base-ten number that uses place value and a decimal point to show 10 th, 100th.
    Decimal Fraction: a fraction that is expressed using decimal notation.
    Mixed Number: a number named by a whole number and a fraction.
