algorithms
step by step methods for solving arithmetic computations
integers
positive or negative whole numbers
rational numbers
1/3 or PI
irrational numbers
infinite 33.33333 or 3.14159…..
real numbers
whole numbers not 0
mean
average
median
middle number in a set or if even number, the average of the two middle numbers in the set
mode
most frequent number in the set, there can be many modes or none in a set
Dienes blocks
base 10 blocks
communicative property
change of order in addition or multiplication
associative property
change of grouping in addition or multiplication
attibute blocks
manipulative for pattern recognition
seriation
changes are gradual (height of students)
topological geometry
location of objects relatvie to each other
Euclidean geometry
descriptions of figures and objects
coordinate geometry
places 2D and 3D shapes into grid system
transformational geometry
moving shapes through space
congruent
match up exactly in size and shape
similar
sides are proportional from one figure to the next
point
no dimension
line
one dimension
plane
two dimensional
angle
formed by two rays with a common endpoint (vertex)
parallel lines
same plane and never intersect, form parallelograms
perpendicular lines
intersect to form right angles, form rectangles, squares, right triangles
Tessellations
tiling patterns repeating a shape in a systematic pattern in order to completely fill a space
translations
sliding motions
rotations
turning motions
reflections
flipping motions
dilations
expansions
contractions
reductions
symmetry
figure falls on itself when folded in half
Kyle hurriedly drew mandolins during class Monday
kilo, hecto, deka (deca), meter, deci, centi, milli
range
subtract the smallest value from the largest value
outlier
one value that is far from the other values in the set
bell curve/normal distribution
representation of a norm referenced event
curve
highest in the middle-greatest frequency
one standard deviation
one stnd. dev above and below the mean represent 68% of all values in the set
mean bell curve
50th percentile
induction
Combining pieces of information to form conclusions, flows from sepcific tidbits to general rules (categorizing shapes)
deduction
go from a rule to specifics (some, all, none)
perimeter of square
p=4s
perimeter of rectangle
p=2l+2w
circumference circle
c=2 Pi r or c=pi d
area triangle
A=bh/2 or A=1/2bh
square area
a=s2
rectangle area
A=lw or a=bh
parallelogram
a=bh
trapezoid area
a=(b1+b2)h/2 or a=1/2(b1+b2)h
circle area
a=pi r2
cube volume
v=s3
rectangular prism volume
v=lwh or v=bh
pi
