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. |

Even + Even numbers | Always equal an even |

Even + Odd numbers | Always equal an odd |

Odd + Odd numbers | Always equal an even |

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. |

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. |
