differencethe answer in subtracting: 11=0
perimeterdistance around a shape
productanswer in a multiplication problem: 10x5=50
Venn diagramtwo (or more) overlapping circles, used for showing how things are the
same and different
segmenta line part with points at both ends
pointa dot on a grid; a location on a grid; something that ends a segment
seta group of data; data is information, things you have recorded; numbers
mixed number3 1/4 a fraction with a whole number
rayline with a point at one end and an arrow at the other; it goes on forever in the direction of the arrow
compatible numbersa close number; for instance, 17+2=19; 20 would be a compatible number; handy for estimation
estimateclose to or a guess at the number
improper fractionsthe top number is higher than the bottom number; 10/7 (should be 1 3/7)
radiusa line from the center of a circle to the perimeter (so a radius measures halfway across the circle)
ratio1:3; 1 to 3; 1/3 percents/fractions written in a different way; compare two numbers to each other
linesegment with an arrow at each end; it goes on forever in BOTH directions
quotientthe answer when you divide; 12/6=2
sumthe answer in addition; 5+6=11
