Sixth grade math lesson on multiplication to download as PDF or print for free with lesson definitions and properties. We will cover the operative techniques for performing or posing a multiplication in rows or columns. The objective is that the student masters the fundamentals of multiplication vocabulary and the calculation of the product of two numbers in the sixth grade.

I. Multiplication of a decimal number by a whole number

1. product and factors

Definition:

Multiplication is the operation that calculates the product of two numbers.

Each number that is multiplied is called the factor of the product.

Example:

$4,2\,\times \,3=12,6$

4,2 and 3 are the factors and 12.6 is the product.

Ownership:

To calculate the product of two factors, we can:

change the order of the factors;
group the factors differently.

Examples:

$4,2\times \,3=12,6\\3\times \,4,2=12,6$ $3\times \,2,5\times \,4=7,5\times \,4=30\\3\times \,2,5\times \,4=3\times \,10=30$

2. Multiply by 10, 100, 1000

Ownership:

When you multiply a number :

by 10, the units digit becomes the tens digit;
by 100, the units digit becomes the hundreds digit;
by 1,000, the number of units becomes the number of thousands.

Example:

$34,5\times \,100=3\,450$

3. operating technique

Rule:

To multiply a decimal number by a whole number :

we start the calculations on the right, without taking into account the decimal point;
the same number of digits after the decimal point is placed in the result as in the decimal number.

Example:

II. Multiplication of two decimal numbers

Multiplication by 0.1; 0.01; 0.001

Ownership:

When you multiply a number :

by 0.1, the units digit becomes the tenths digit;
by 0.01, the units digit becomes the hundredths digit;
by 0.001, the units digit becomes the thousandths digit.

Example:

$45,6\times \,0,01=0,456$

2.Operating technique

Rule:

To perform a multiplication of two decimal numbers :

it is first performed without taking commas into account;
the same number of digits after the decimal point as the total number of digits after the decimal point in the two factors is placed in the result.

Example:

Rule:

To get an order of magnitude of a product, we multiply an order of magnitude of each of the factors.

Example:

An order of magnitude of 1.95 is 2.

An order of magnitude of 4.2 is 4; therefore an order of magnitude of $1,95\times \,4,2$ is $2\,\times \,4$ or 8.

3. operating priorities

Rule:

Calculations in parentheses take precedence;
Multiplication takes precedence over addition and subtraction.
