|---|---|---|---|---|---|
| Integer | Set of whole numbers and their opposites.
No fractions or decimals.
Includes:
• the counting numbers {1, 2, 3, ...},
• zero {0},
• and the negative of the counting numbers {-1, -2, -3, ...}
🗑
|
||||
| Whole number | Zero and positive numbers with no fractional or decimal part.
{0,1,2,3,4,5...}
🗑
|
||||
| Opposite Numbers | Numbers that have the same magnitude but are on opposite sides of zero on the number line
Opposites have the same absolute value.
🗑
|
||||
| Absolute Value | The distance a number is from zero on the number line.
🗑
|
||||
| Number Line | A line on which numbers are marked at intervals, used to
illustrate simple numerical operations.
A number line can be horizontal or vertical.
🗑
|
||||
| Origin | Zero on a number line.
🗑
|
||||
| Horizontal | In a side-to-side direction.
🗑
|
||||
| Vertical | In an up-down direction or position. Upright.
Example: trees grow in a vertical direction.
🗑
|
||||
| Sum | The answer to an addition problem.
🗑
|

|
||||
| Coordinate Plane | The plane containing a horizontal number line, the "x" axis and a vertical number line, the "y" axis.
🗑
|
||||
| Coordinates | A set of values that show an exact position.
On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down.
🗑
|
||||
| Ordered Pair | A pair of numbers used to show the position on a graph, where the "x" (horizontal) value is first, and the "y" (vertical) value is second.
Usually written in parentheses like this: (12,5)
🗑
|
||||
| Quadrant | Any of the 4 areas made when we divide up a plane by an x and y axis.
They are usually numbered I, II, III and IV
🗑
|
||||

🗑
|
||||
| Diameter | Any line segment from one point on a circle going through the center of the circle to another point on the circle.
🗑
|
||||
| Chord | Any line segment starting from one point on a circle to another point on the circle.
🗑
|
||||
| Radius | Any line segment from the center of a circle to a point on the circle.
🗑
|
||||
| Symmetry | When two or more parts are identical after a flip, slide or turn.
🗑
|
||||
| Congruent | Figures that are the same shape and size
🗑

🗑
|
||||
| Parallelogram | A quadrilateral with 2 pairs of congruent parallel sides
🗑
|
||||
| Acute angle | An angle that is less than 90 degrees.
🗑
|
||||
| Obtuse Angle | An angle that is more than 90 degrees.
🗑
|
||||
| Right Angle | An angle that measures exactly 90 degrees.
🗑
|
||||
| Isosceles Triangle | A triangle with two congruent sides and angles.
🗑
|
||||
| Equilateral Triangle | A triangle with all three congruent sides and angles.
🗑
|
||||
| Scalene Triangle | A triangle with no congruent sides or angles.
🗑
|
||||
| Regular Polygon | A polygon with all interior angles and all sides congruent.
🗑
|
||||
| Ratio | A comparison of two or more quantities. Can be written as a:b, a to b, or a/b.
🗑
|
||||

|
||||
| Improper Fraction | A fraction whose numerator is greater than or equal to the denominator.
🗑
|
||||
| Mixed Number | A number that contains a whole number and a fraction.
🗑
|
||||
| Reciprocal | A flipped version of the number or fraction. In other words, 1 divided by that number. When we multiply a number by its reciprocal we get 1. Ex: 3/4 and 4/3 are reciprocals
🗑
|
||||
| Inverse | Opposite.
The inverse of adding 9 is subtracting 9.
The inverse of multiplying by 5 is dividing by 5
🗑
|
||||
| Inverse Property of Addition | The sum of a number and its negative (the "additive inverse") is always zero. a + (−a) =
🗑
|
||||
| Inverse Property of Multiplication | Multiplying a number by its reciprocal (the "multiplicative inverse") is always one. a × (1/a) = 1
