Dividing decimals by an entire quantity could be a tough idea for college kids to understand. Nonetheless, by utilizing photos, you may make the method way more concrete and simpler to grasp. On this article, we’ll present step-by-step directions on the best way to educate dividing decimals by an entire quantity pictorially, with loads of examples as an example every step. With these clear and interesting visuals, your college students will be capable of grasp this vital math talent very quickly.
To start, it is very important evaluate the idea of dividing complete numbers. Ask college students to think about they’ve a sure variety of objects, akin to candies or cash, and they should divide them equally amongst a sure variety of folks.

As soon as college students perceive the best way to divide complete numbers, you’ll be able to introduce the idea of dividing decimals.
To divide a decimal by an entire quantity pictorially, merely comply with these steps:
1) Draw an image to symbolize the dividend (the quantity being divided).
2) Draw a smaller image to symbolize the divisor (the quantity dividing into the dividend).
3) Divide the dividend image into equal teams, with the variety of teams equal to the divisor.
4) Rely the variety of teams to seek out the quotient (the reply to the division downside).
Setting up Fraction Bars for Decimal Division
Dividing decimals by complete numbers will be simplified utilizing fraction bars. Here is the best way to assemble fraction bars pictorially:
Step 1: Draw the Dividend and Divisor
Draw a horizontal line to symbolize the dividend (the decimal being divided). Under it, draw one other horizontal line to symbolize the divisor (the entire quantity).
| Dividend | Divisor |
|---|---|
| —– | —– |
Step 2: Align the Decimal Factors
Align the decimal level of the dividend and the divisor vertically. If the dividend does not have a decimal level, add one on the finish.
| Dividend | Divisor |
|---|---|
| —–. | —– |
Step 3: Assemble Equal-Sized Rectangles
Draw a collection of equal-sized rectangles above the dividend and divisor. These rectangles will symbolize fractions of the dividend and divisor.
| Dividend | Rectangles | Divisor | |||
|---|---|---|---|---|---|
| —–. | —– | ||||
Step 4: Divide the Dividend and Divisor
Divide the size of the rectangle on the dividend line by the size of the rectangle on the divisor line. This offers you the quotient, which is the reply to the division downside.
| Dividend | Rectangles | Divisor | |||
|---|---|---|---|---|---|
| —–. | —– | ||||
| Quotient | |||||
Methods to Train Dividing Decimals by a Entire Quantity Pictorially
Dividing decimals by an entire quantity could be a difficult idea for college kids. To assist make it extra comprehensible, it’s useful to make use of pictorial representations. Here’s a step-by-step information on the best way to educate dividing decimals by an entire quantity pictorially:
- Convert the entire quantity to a decimal. For instance, 5 will be transformed to five.0.
- Place the decimal level within the dividend. The dividend is the quantity being divided.
- Divide as standard. Simply as you’ll divide an entire quantity by an entire quantity, divide the digits within the dividend by the digits within the divisor.
- Carry down the decimal level. The decimal level within the quotient (the reply) ought to be immediately above the decimal level within the dividend.
- Proceed dividing till there are not any extra digits within the dividend. If there are any remainders, they are often expressed as a decimal fraction.
For instance, let’s divide 12.6 by 3.
As you’ll be able to see, the reply is 4.2.
