A triangle with 3 congruent sides Equilateral
Order of Operations 1. Parentheses 2. Exponents 3. Multiplication/Division (left to right) 4. Addition/Subtraction (left to right)
Skip Counting Skip counting is counting by 2 or 5 or 10 and so forth.
A triangle less than 90 Acute
Triangle 3 sides
Quadrilateral 4 sides
Pentagon 5 sides
Hexagon 6 sides
Heptagon 7 sides
Octogon 8 sides
Nonogon 9 sides
Decagon 10 sides
Mean Average, add up all the numbers in a set of values, then divide that number by the number of numbers in the set
Complementary Angles Two angles that together equal 90
Supplementary Angles Two angles that together equal 180
Range The largest number minus the smallest number in a set of values
Straight Angles Measures 180
Interior Angle of a Triangle 60
Interior Angle of a Square 90
Interior Angle of a Pentagon 108
Interior Angle of a Hexagon 120
Parallel Lines Equals 180 (also known as straight angles)
Surface Area Surface area is the sum of the lateral surface area and the area of bases.
Perimeter The sum of the length of it's sides.
Volume Number of unit cubes it will hold.
Weight Force exerted by a gravitational pull.
Mass The quantity of matter, as opposed to the weight of the object.

Square A rectangle with two adjacent sides congruent. Equivently a square is a quadrilateral with four right angles and four congruent sides.
Rhombus A parallelogram with two adjacent sides congruent.
Rectangle A parallelogram with a right angle. Equivalently a rectangle is a quadrilateral with four right angles.
Parallelogram A quadrilateral on which each pair of opposite sides is parallel.
Isosceles Trapezoid A trapezoid with exactly one pair of congruent sides. Equivalently an isosceles trapezoid is a trapezoid with two congruent base angles.
Kite A quadrilateral with two sides adjacent and congruent. The other two sides are also congruent.
Greatest Possible Error The GPE is a measurement one-half the unit used. For example, if the width of a peice of board was measured to the nearest centimeter as 5cm, the actual width must be between 4.5cm and 5.5cm.
Rote Counting -The child is able to recite the number name sequence correctly.
Graphs Graphs should have 1. Title 2.Lables on both axes 3. Source of data 4. Key to pictograph 5. Uniform size of symbols in pictograph 6. Scale: is the break shown 7. Scale: are the numbers equally spaced.
Area The surface included within a set of lines; specifically: the number of unit squares equal in measure to the surface.
Circumference the external boundary or surface of a figure or object
Formula to find missing leg of hypotenuse of a triangle Use this formula for both problems A(to the second power) + B(to the second power)= C squared
Definition of Rote Counting Child has no number concept
Even divided by Even Answer can be even or odd
Graphing Calculators have enriched learning in which ways? 1. Tools for expediency 2. Amplifiers for conceptual understanding. 3. Catalysts for critical thinking. 4. Vehicles for integration.
When to use four operation calculators Adding, Subtraction, Multiplication, Division
Cubit A cubit is equal to one forearm
Vertical Angles These are two angles whose sides form two pairs of opposite rays. We can think of these as opposite angles formed by an X.
Even-Odd Equals Odd

Rational Counting A child uses one-to-one correspondence between objects and numbers.
4 Types of Statistical Bias 1. Relying on voluntary response 2. Undercoverage of population 3. Non-Response Bias 4. Response Bias
Example of One-to-One Correspondence Suppose a child knows how to count only to 3. The child might still tell that there are as many fingers on the left hand as on the right hand by matching the fingers up.
