MATH VOCABULARY
For each math notecard: FRONT (bold)Word
BACK (non-bold) Definition and example
UNIT 1-4
#1-Numerator: number of parts being taken
-4/5 (the 4 is the numerator)
#2-Denominator: number of equal parts
-4/7 (the 7 is the denominator)
#3-Expanded form: a way to write numbers that shows the value of every digit
-53.2 50 + 3 + .2
#4-Greater than or equal to (front)
>
#5-Less than or equal to (front)
<
#6--Commutative Property
a+b=b+a
axb=bxa
#7--Associative Property
(a + b) + c = a + (b + c)
(a x b) x c = a x (b x c)
#8--Distributive Property
a x (b + c) = (a x b) + (a x c)
#9-Dividend: the amount to be divided (example: 10 / 5 = 2, 10 is the dividend)
#10-Divisor: the number of parts the dividend will be divided by (example: 10 / 5 = 2, 5 is the divisor)
#11-Quotient: the result of a division problem (example: 10 / 5 = 2, 2 is the quotient)
UNIT 5
#12-Volume: The amount of space a liquid, solid, or gas takes up
-l x w x h
OR
bxh
-measured in cubic units
UNIT 6
*Include a picture for each of the triangles. The picture is your example. See your TRIANGLE
ORGANIZER sheet for an example of EACH.
#13-Acute Triangle-A triangle with three acute angles
#14-Obtuse Triangle-A triangle with one obtuse angle
#15-Right Triangle-A triangle with one right angle
#16-Scalene Triangle-A triangle with NO congruent sides (all sides and angles are different)
#17-Equilateral Triangle-A triangle in which all 3 sides and angles are congruent
#18-Isoscles Triangle-A triangle in which 2 sides and 2 angles are congruent
*You do NOT need to include a picture or example for #19-26. You need to focus more on the
definition rather than the picture. See QUADRILATERAL DEFINITIONS sheet for more notes.
