Learn basic arithmetic operations and their facts
Addition, subtraction, division, and multiplication are the four basic operations in mathematics. These operations are essential for solving problems and understanding mathematical concepts. Children need to learn these concepts and operations in order to succeed in mathematics.
Addition: Addition is the mathematical operation of finding the sum of two or more numbers. For example, 3 + 2 = 5, meaning that 3 and 2 are added together to make 5. Kids can learn addition using simple examples such as counting fingers or using manipulatives like blocks or counting bears.
Subtraction: Subtraction is the mathematical operation of finding the difference between two numbers. For example, 5 – 2 = 3, meaning that 2 is subtracted from 5 to give a difference of 3. Subtraction is the inverse operation of addition, and kids can learn subtraction by using manipulatives like blocks or counting bears and taking them away to find the difference.
Division: Division is the mathematical operation of finding how many times one number is contained in another. For example, 8 ÷ 2 = 4, meaning that 2 can be contained in 8 four times. In other words 8 can be split into 4 groups with 2 in each group. Division is the inverse operation of multiplication, and kids can learn division by using manipulatives like blocks or pictures of groups of objects and counting how many are in each group.
Multiplication: Multiplication is the mathematical operation of finding the product of two or more numbers. For example, 2 x 3 = 6, meaning that 2 is multiplied by 3 to give a product of 6. Multiplication is a shorthand way of writing repeated addition and is introduced after kids have mastered addition.
It’s important to note that, while each operation is distinct, they are closely related and depend on each other. And that is a key concept in solving math problems, because once a child understand how they are related they can use the knowledge in one area to solve problems in other area.
Some facts that can be helpful for children to know:
- The commutative property of addition states that the order of numbers being added does not affect the sum. For example, 2 + 3 = 3 + 2.
- The commutative property of multiplication states that the order of numbers being multiplied does not affect the product. For example, 2 x 3 = 3 x 2.
- The associative property of addition states that the order in which numbers are grouped does not affect the sum. For example, (2 + 3) + 4 = 2 + (3 + 4).
- The associative property of multiplication states that the order in which numbers are grouped does not affect the product. For example, (2 x 3) x 4 = 2 x (3 x 4).
It is also important to mention that visual representation like bar diagrams, number lines, etc can be extremely helpful for the kids in understanding these concepts better.
