Numbers are separated into groups: ones, tens, hundreds, thousands, millions, and so on. Each group contains three subgroups: ones, tens, and hundreds. When writing or reading a large number, begin at the left with the largest group, and proceed to the right. For instance, 7,482 is read as seven thousand, four hundred, eighty-two. The following chart can help in reading large numbers.
Multiplication Chart
So, let’s say we want to know what 5 x 4 is.
Row = Across
Column = Up and donw.
To find 5 x 4, we must find the row that shows the 4 times tables and the column that shows the 5 times table. Then we look for the box where the they overlap: is 20

Array-A multiplication array is simply an arrangement of rows or columns that matches a multiplication equation. Objects 3x4=12
3 x 4 = 12
rows x # in each row = total
Addend- Any of the numbers that are added together.
addend + addend = Sum
Example: In 8 + 3 = 11, the 8 and the 3 are addends.
The first number in a subtraction. The number from which another number (the Subtrahend) is to be subtracted.
minuend − subtrahend = difference
Example: in 8 − 3 = 5, 8 is the minuend.
Multiplication sentence- A multiplication sentence consists of two parts: one part is a mathematical expression and the other part is the product. In multiplication, a mathematical expression is the part of the sentence that comes before the equal sign.
Factors and Products- Multiplying two whole numbers gives a product. The numbers that we multiply are the factors of the product. Example: 3 × 5 = 15 therefore, 3 and 5 are the factors of 15.
Division has 4 parts: divisor, dividend, quotient and remainder. A division sentence is a number sentence that uses the operation of division. Division has an opposite operation, which is multiplication. Multiplication and division 'undo' or 'reverse' each other. We can use the opposite operation of multiplication, or we can use repeated addition, to complete a division sentence.
A tape diagram is a rectangular drawing that appears like a tape piece with divisions to support mathematical calculations. It is a graphic tool used commonly in solving ratio-based mathematical word problems. Tape diagrams are visual representations that represent the sections of a ratio by using rectangles.
Skip counting can be defined as the method of counting forward by numbers other than 1. To skip count, we keep adding the same number each time to the previous number. Here, we are skip counting by 2 on a number line.
The four main number properties are:
Commutative Property.
Associative Property.
Identity Property.
Distributive Property.
Commutative Property of Multiplication- The commutative property of multiplication tells us that it doesn't matter in what order you multiply numbers. The formula for this property is: a x b = b x a. For example, it doesn't matter if we multiply 5 x 4 or 4 x 5. We will end up with the same answer 20.
Commutative Property of Adding- 1+2=3 and 2+1=3
Note: When you type on the keyboard, multiplication symbol for x = *
According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
The distributive property tells us how to solve expressions in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. ... Then we need to remember to multiply first, before doing the addition! We got the same answer, 44, with both approaches!
Decompose
Decompose: To decompose in math is to break down numbers into parts. Add: To add is to join two numbers together. Subtract: To subtract is to take away from another to see the difference. Place Value: Place value is the value represented by a digit in a number on the basis of its position in the number.
The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Add some parenthesis anywhere you like!.
The identity property of 1 says that any number multiplied by 1 keeps its identity. In other words, any number multiplied by 1 stays the same. The reason the number stays the same is because multiplying by 1 means we have 1 copy of the number. For example, 32x1=32.
Multiplication and division are closely related, given that division is the inverse operation of multiplication. When we divide, we look to separate into equal groups, while multiplication involves joining equal groups. ... If we divide this product by one of the factors, we get the other factor as a result.
A gram, or gramme, is a unit of measure in the metric system. It measures mass, or how much matter something is. The symbol is g. One gram used to be defined as the mass of one cubic centimetre of pure water at 3.98 degrees Celsius. Now one gram is defined as 1/1000 of a kilogram
The kilogram[b] is the base unit of mass in the International System of Units (SI). It is in widely used in science, engineering, and commerce worldwide. The kilogram is exactly the mass of one litre of water. The symbol is kg.
The word milliliter literally means one thousandth ("milli") of a liter.
Liter
A liter is just a bunch of milliliters put all together. In fact, 1000 milliliters makes up 1 liter:
1 liter = 1,000 milliliters
What is an example of an estimate?
To find a value that is close enough to the right answer, usually with some thought or calculation involved. Example: Alex estimated there were 10,000 sunflowers in the field by counting one row then multiplying by the number of rows.
What Are You Rounding to?
When rounding a number, you first need to ask: what are you rounding it to? Numbers can be rounded to the nearest ten, the nearest hundred, the nearest thousand, and so on.
Consider the number 4,827.
4,827 rounded to the nearest ten is 4,830
4,827 rounded to the nearest hundred is 4,800
4,827 rounded to the nearest thousand is 5,000
All the numbers to the right of the place you are rounding to become zeros. Here are some more examples:
34 rounded to the nearest ten is 30
6,809 rounded to the nearest hundred is 6,800
1,951 rounded to the nearest thousand is 2,000

measuringtape-A4.pdfMetric system ruler
A metric ruler is the standard instrument for measurement in the scientific laboratory. On a metric ruler, each individual line represents a millimeter (mm). The numbers on the ruler represent centimeters (cm). There are 10 millimeters for each centimeter
The metric system is based on multiples of 10. For example, 10 millimeters equal 1 centimeter, 100 centimeters equal 1 meter, and 1000 meters equal 1 kilometer. The basic unit of length in the metric system is the meter.
A set containing nothing, an empty set. a null set has a cardinal number of 0.
Null or empty
• a set containing nothing, an empty set.
• a null set has a cardinal number of 0.
• may be indicated by a Ø or { }
Parentheses are used in mathematical expressions to denote modifications to normal order of operations (precedence rules). In an expression like , the part of the expression within the parentheses, , is evaluated first, and then this result is used in the rest of the expression.
How Do I Remember It All ... ? PEMDAS !
P= Parentheses first
E= Exponents (ie Powers and Square Roots, etc.)
MD=Multiplication and Division (left-to-right)
AS= Addition and Subtraction (left-to-right)
"Operations" mean things like add, subtract, multiply, divide, squaring, etc. If it isn't a number it is probably an operation.
But, when you see something like ...
7 + (6 × 52 + 3)
... what part should you calculate first?
Start at the left and go to the right?
Or go from right to left?
Warning: Calculate them in the wrong order, and you can get a wrong answer !
Note: Don't worry about Exponent you will learn that later.
Order of Operations
Step 1. Do things in Parentheses First
4 × (5 + 3)=4 × 8=32
4 × (5 + 3)=20 + 3=23 (wrong)
Step 2. Exponents (Powers, Roots) before Multiply, Divide, Add or Subtract. (Don't worry about Exponets until
5 × 22=5 × 4=20
5 × 22=102=100 (wrong)
Step 3.Multiply or Divide before you Add or Subtract
2 + 5 × 3=2 + 15=17
2 + 5 × 3=7 × 3=21(wrong)
Step 4. Otherwise just go left to right
30 ÷ 5 × 3=6 × 3=18
30 ÷ 5 × 3=30 ÷ 15=2 (wrong)
Fact Family + and -
What is a fact family in addition and subtraction?
In math, a fact family can be defined as a group of math facts or equations created using the same set of numbers. The fact family shows the relationships between the three numbers involved. In an addition and subtraction fact family, there are four addition and subtraction sentences created using three numbers.
Fact family x and /
A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts. For example, you can form a fact family using the three numbers 10, 2, and 12: 10 + 2 = 12, 2 + 10 = 12, 12 − 10 = 2, and 12 − 2 = 10.
Which are the square numbers?
A square number is the result when a number has been multiplied by itself. For example, 25 is a square number because it's 5 lots of 5, or 5 x 5. This is also written as 52 (“five squared”).
A fraction is a part of a whole number, and a way to split up a number into equal parts. It is written as the number of equal parts being counted, called the numerator, over the number of parts in the whole, called the denominator. These numbers are separated by a line.
What is numerator or denominator?
The numerator represents how many parts of that whole are being considered, while the denominator represents the total number of parts created from the whole. In the fraction above, the whole value (say, an apple pie) has been divided into 5 equal parts.
Equivalent Fractions-When fractions have different numbers in them, but have the same value, they are called equivalent fractions. These fractions have the same value, but use different numbers. ... You can see from the picture below that they both have the same value.
Geometry is a kind of mathematics that deals with shapes and figures. Geometry explains how to build or draw shapes, measure them, and compare them. People use geometry in many kinds of work, from building houses and bridges to planning space travel.
Geometrical shapes are the figures or objects that we see around us everywhere. These different shapes of geometry are made up of lines, curves, angles, and surfaces. The shapes in geometry can be either open or closely bound.
Types and Properties of Geometric Shapes
Go through the different types of shapes in geometry along with definitions here.
Triangle
Triangle is a polygon, which is made of three sides and consists of three edges and three vertices. Also, the sum of its internal angles equals to 180o.
Circle
Locus of all points at a fixed distance from a reference central point is called a Circle.
Square
Square is a quadrilateral where all the four sides and angles are equal and the angles at all the vertices equal to 90° each.
Rectangle
A quadrilateral which has its two pairs of opposite sides equal in length and interior angles are at the right angles.
Parallelogram
A parallelogram is a quadrilateral with two pairs of parallel sides and opposite angles are equal in measures.
Quadrilaterals
just means "four sides" (quad means four, lateral means side). A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
Geometry is a kind of mathematics that deals with shapes and figures. Geometry explains how to build or draw shapes, measure them, and compare them. People use geometry in many kinds of work, from building houses and bridges to planning space travel.
An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle. The word angle comes from a Latin word named 'angulus,' meaning “corner.”
Polygons
These are made up of line segments and no curves. They are enclosed structure based on different length of sides and different angles.
Width or breadth usually refer to a shorter dimension when length is the longest one. ... Length is the measure of one spatial dimension, whereas area is a measure of two dimensions (length squared) and volume is a measure of three dimensions (length cubed).
Reading a ruler
If you counted in 1/4 inches on a ruler, you'd see that the fourth line after 0 inches equals 1/4 inch, the eighth line equals 2/4 (1/2) inch, and the 12th line equals 3/4 inch. Example: Say you're measuring a piece of cloth and the ruler ends at the fourth line after the 10-inch mark.
To find the area of a rectangle, multiply the width by the height. Let's use this formula to find the width of the green rectangle. First, know the width and height. The width is 3 square units, and the height is 2 square units.
The perimeter of a square is the total length of the four equal sides of the square. The perimeter of a rectangle is the total length of the two lengths and two widths of the rectangle.
Improper fraction:
A fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number). So it is usually "top-heavy". Example: 5/3 (five thirds) and 9/8 (nine eighths) are improper fractions.
Mixed Fraction Numbers
A mixed number is a whole number, and a proper fraction represented together. It generally represents a number between any two whole numbers.
Proper Fraction Mixed Number Fraction
How to do Multiplication Multi-Digit
Before we begin, let's review what the multiplication terms are: Factors: Factors are numbers that are being multiplied. Product: The product is the result of the multiplication. Multiplicand: The multiplicand is the number (factor) that gets multiplied
How to do Long division
The long division method involves basic math operations. To divide two numbers using this method, a tableau is drawn. The divisor is written outside the right parenthesis, while the dividend is placed within. The quotient is written above the over bar on top of the dividend.
The exponent of a number says how many times to use the number in a multiplication.
In 82 the "2" says to use 8 twice in a multiplication,
so 82 = 8 × 8 = 64
In words: 82 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared"
Exponents are also called Powers or Indices.
Some more examples:
Example: 53 = 5 × 5 × 5 = 125
In words: 53 could be called "5 to the third power", "5 to the power 3" or simply "5 cubed"
