Clues to Add    How many in all? What is the total? What is the sum? How many altogether? How many
combined?
Clues to Subtract    What is the difference? How many more? How many are left? How much longer,
shorter, taller, heavier? How much change?
Denominator    the bottom number of a fraction – tells how many parts there are
Difference    the answer you get when you subtract
Double    a number twice    12+12=24 or 12x2=24
Estimate    to find a number that is close to an exact amount by rounding
Equivalent    having the same value – equal
Factor    a number multiplied
Half    to divide into 2 equal groups    14 ÷ 2 = 7
Mixed Number    a whole number and a fraction    Example 2 3/Numerator    the top number of a fraction – tells how many parts are shaded
Product    the answer you get when you multiply
Quotient    the answer you get when you divide
Round    to replace a number with one that tells about how much or how many
Sum    the answer you get when you add
