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. |

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. |

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. |
