1even number Numbers ending in 0, 2, 4, 6, or 8. A number divisible by 2.Numbers ending in0, 2, 4, 6, or 8.
2A number NOT divisible by 2. odd numberA number NOT divisible by 2.Numbers ending in1, 3, 5, 7, 9.
3also called the Grouping Property associative propertyof multiplicationWhen three or more numbers are multiplied, the product is the same regardless of the grouping of the factors.(2 x 3) x 4 = 242 x (3 x 4) = 24(2 x 4) x 3 = 24also called the Grouping Property
4The numbers added together addendThe numbers added togetherto form a sum.= 15sum
5factors The numbers that are multiplied in a multiplication problem. 3 x 5 = 15product
6sum difference product quotient the answer to an addition problemdifferencethe answer to a subtraction problemproductthe answer to a multiplication problemquotientthe answer to a division problem
7commutative property of multiplication The property that states that changing the order of the factorsdoes not affect the product.Example:3 x 5 = and x 3 = 15
8line A straight path that extends A straight path that extendsin both directions without end; marked with an arrowhead ateach end.
9A piece of a line that has line segmentA piece of a line that hastwo endpoints.
10parallel linesTwo (or more) lines that run the same distance apart at every point and will never intersect.para ellllines
11A line with one end point that extends non-stop in the rayA line with one end point that extends non-stop in theopposite direction.
12A shape formed by two rays that share an endpoint. angleA shape formed by two rays that share an endpoint.
13vertex plural: vertices The point where: two or more rays share an endpoint.the edges of a solid figure meet.The point at the top of a cone.
14intersecting linesTwo or more lines thatmeet or cross at a point.
15Two lines that intersect perpendicular linesTwo lines that intersectand form right angles.
16Tool used to measure angles. protractorTool used to measure angles.
171 rotation = 90° 2 rotations = 180° 3 rotations = 270° A full circle rotation is equal to 360° (degrees)When divided into four equal sections, each section is worth 90°1 rotation = 90°2 rotations = 180°3 rotations = 270°4 rotations = 360°360°90°90°90°270°90°90°90°90°90°180°
19acute angleAn angle that measuresLESS than 90 degrees.
20obtuse angleAn angle that measuresMORE than 90 degrees.
21straight angleAn angle that measures180 degrees.
22polygon four criteria for a A polygon is made up of all straight line segmentsis closed (has no breaks in the line segments)is 2-dimensitionalhas no lines that cross over each other
23A polygon with all equal sides and all equal angles. regular polygonA polygon with all equal sides and all equal angles.
24have all equal sides and irregular polygonA polygon that does NOThave all equal sides andequal angles.
25rectangle A rectangle: four criteria of a is a quadrilateral. is a quadrilateral.is made up of four line segments.has four 90° angles.is a parallelogram – a four sided polygon with two pairs of parallel sides.
26A quadrilateral (four sided polygon) with two pairs of parallel sides. parallelogramA quadrilateral (four sided polygon) with two pairs of parallel sides.
27A quadrilateral (four sided polygon) with one pair of parallel sides. trapezoidA quadrilateral (four sided polygon) with one pair of parallel sides.
28congruent Figures that have the same size AND same shape. The figures do not have be in the same position.If you placed the two shapes directly on top of eachother they would match up perfectly.
29similarFigures that have the same shape,but are not the same size.
30line of symmetry The line that divides a figure in half so that both halves are exactlythe same.
31A triangle with all three equilateraltriangleA triangle with all threesides of equal length.3 in.3 in.3 in.

47area The number of square units that can fit inside of a shape. To find the _______ , countthe square units.area = 9 square units
48perimeter The distance around the outside of a shape. perimeter To find the __________ , add the length of all the sides.perimeter2 cm + 3 cm + 3 cm = 8 cm The perimeter of this figure is8 centimeters.

83Example: 634,822Standard Form: 634,822Word Form: six hundred thirty-four thousand, eight hundred twenty-twoExpanded Form: 600, , , = 634,822What is the value of the underlined digit in the number 634,822 = 600,000What place value does the underlined digit hold? = hundred thousands
84Distributive Property of Multiplication The property that states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products.break down the 8 into 5 + 37 x 85 + 3(7 x 5) + (7 x 3)= 56break down the 16 into5 x 1610 + 6(5 x 10) + (5 x 6)= 80
85Identity Property of Multiplication The property that states that the product of any number and 1 is that number.Examples:5 × 1 = 5248 x 1 = 2481 × 8 = 8
