Addition Mini-Lesson

Welcome to the world of numbers! It’s time to dive into one of the fundamental operations in mathematics: addition. This mini-lesson is designed to help you grasp the basic concepts of addition and provide you with some practice questions.

Basic Concepts of Addition

Addition is the mathematical process of combining two or more quantities to find the total number or sum. When combining collections or sets, it’s the total sum of objects you have. The symbol used to represent addition is ‘+’.

For example, if you have 2 apples and add 3 more apples, you will have 5. It can be represented as 2 + 3 = 5 in mathematical terms.

Here, ‘2’ and ‘3’ are known as addends, and ‘5’ is the sum. The equation reads as “two plus three equals five.”

Properties of Addition: Addition has three main properties – commutative, associative, and identity.

1. Commutative Property: This property states that changing the order of addends does not change the sum. For example, 4 + 3 = 7 and 3 + 4 = 7.

2. Associative Property: This property states that when three or more numbers are added, the sum is the same regardless of how the numbers are grouped. For example, (2 + 3) + 4 = 9 and 2 + (3 + 4) = 9.

3. Identity Property: This property states that if you add zero to any number, the sum is that number itself. For example, 5 + 0 = 5.

Examples and Practice Questions


  1. If you have 5 pencils and your friend gives you another 4 pencils, how many pencils do you have in total? The equation for this would be: 5 + 4 =?
  2. If there are 6 birds on a tree and another group of birds with a count of 7 joins them, how many birds are there? The equation for this would be: 6 +7 =?

Practice Questions:

  1. You have three candies, and your friend gives you two more candies. How many sweets do you have now?
  2. A party has seven balloons, and someone brings in five more balloons. How many balloons are there now?

Remember, practice makes perfect! The more problems you solve, the better your understanding will be.

Here’s a quick recap table:


Basic Concepts – Addition is combining collections or sets.

– ‘+’ is the symbol for addition.

– The numbers being added are called addends.- The result of an addition problem is called the sum.- Addition has three properties: commutative, associative, and identity.

Examples & Practice Questions – Example: If you have ‘x’ items and get ‘y’ more, how many items do you have? The equation would be x + y = ?- Practice Question: You have ‘a’ items and get ‘b’ more. How many items do you have now?

Subtraction Mini-Lesson

Welcome to your mini-lesson on subtraction! This fundamental mathematical operation is an essential skill you’ll use in various aspects of your life, from calculating change to solving complex equations.

Basic Concepts of Subtraction

Subtraction is one of the four basic arithmetic operations, along with addition, multiplication, and Division. It’s the process of taking away a certain number from another. The result of a subtraction operation is called the difference.

In a subtraction equation, the number you start with is called the minuend, the number you subtract is the subtrahend, and the result is the difference. For example, in the equation 5 – 3 = 2, 5 is the minuend, 3 is the subtrahend, and 2 is the difference.

Examples and Practice Questions

Example 1: How many are left if you have 10 apples and eat 4? The problem can be represented as 10 (minuend) – 4 (subtrahend) =? (difference). So, if you subtract 4 from 10, you’re left with 6 apples.

Example 2: You have $20 and want to buy a book that costs $15. How much money will you have after buying the book? In this case: 20 (minuend) – 15 (subtrahend) = ? (difference). After subtracting 15 from 20, you’ll have $5 left.

Practice Question: You have been saving money for a new game that costs $50. You currently have $30. How much more money do you need to buy the game?

Remember to practice regularly to master subtraction skills. It’s not just about getting an answer but understanding the process.

Here’s a table summarizing what we’ve learned:


Minuend The number from which another number is subtracted. In “10 – 4 = 6”, “10” is the minuend.

Subtrahend The number to be subtracted from another. In “10 – 4 = 6”, “4” is the subtrahend.

Difference The result of subtracting one number from another In “10 – 4 = 6”, “6” is the difference.

Now that you’ve learned about subtraction’s basic concepts and practiced with some examples, it’s time for some independent practice. Keep practicing until you’re comfortable with this essential math skill!

Multiplication Mini-Lesson

As an eager learner, you’re ready to dive into the world of multiplication. This mini-lesson is designed to help you understand the basic concepts of multiplication and provide some examples and practice questions to help you get started.

Basic Concepts of Multiplication

Multiplication is one of the four fundamental mathematical operations, alongside addition, subtraction, and division. It’s a fast way of adding the same number multiple times. For example, instead of adding 2 + 2 + 2 + 2 + 2, you can multiply 2 by 5 to get the same result: 10.

Here’s a simple way to visualize this: If you have five groups of two apples each, how many are in total? The answer is 10, the same as multiplying 5 (the number of groups) by 2 (the number of apples in each group).

Examples and Practice Questions

Now that you understand the basic concept let’s look at some examples.

Example 1: What is 4 multiplied by 3? The answer is 12. It is because you have four or three groups of four.

Example 2: What is 7 multiplied by 6? The answer is 42. It means you have seven groups of six or six groups of seven.

Now, let’s try some practice questions:

  1. What is 5 multiplied by 4?
  2. What is 9 multiplied by 3?
  3. What is 6 multiplied by 7?

Take your time to work out these problems. Remember, multiplication is a faster way of adding the same number multiple times.

Here’s a table summarizing what we’ve covered:

Division Mini-Lesson

Welcome to your math mini-lesson on Division! It is a fundamental concept in mathematics that you’ll use regularly, whether you’re dividing a pizza among friends or calculating the average speed of a car. So, let’s dive right in and learn about Division.

Basic Concepts of Division

The Division is one of the four basic operations in arithmetic, alongside addition, subtraction, and multiplication. It is essentially splitting or separating a number into equal parts. When you divide, you are distributing a set amount equally among a certain number.

The number being divided is called the dividend. The number you are dividing by is the divisor. The result of the Division is known as the quotient. If there is anything left over, it’s called the remainder.

For instance, if you have 12 apples (dividend) and you want to divide them equally among 4 friends (divisor), each friend will get 3 apples (quotient). There will be no apples left over (remainder).

Examples and Practice Questions

Let’s put this into practice with some examples:

Example 1: Divide 20 by 5. Here, 20 is your dividend, and 5 is your divisor. When you divide 20 by 5, your quotient is 4. There’s no remainder because 20 can be evenly divided by 5.

Example 2: Divide 18 by 7. In this case, when you divide 18 (dividend) by 7 (divisor), your quotient is 2, and your remainder is 4 because two sevens are fourteen, and there are four left from eighteen.

Now it’s your turn to practice:

  1. Divide 15 by 3.
  2. Divide 27 by 9.
  3. Divide 36 by 6.
  4. Divide 25 by 7.

To check your answers:

  1. The quotient for the first problem should be 5 with no remainder.
  2. For the second problem, the quotient should be 3 with no remainder.
  3. In the third problem, your quotient should be 6 with no remainder.
  4. For the fourth problem, your quotient should be 3, and your remainder should be 4.

Remember that practice makes perfect! Keep working on these division problems; you’ll soon be a pro!
