 # Multiply Four-Digit Numbers by a One-Digit Number

In this worksheet, student use a column method to multiply four-digit numbers by a one-digit number Key stage:  KS 2

Curriculum topic:   Number: Multiplication and Division

Curriculum subtopic:   Multiply Numbers to Four Digits

Difficulty level:   ### QUESTION 1 of 10

In this activity, we will learn about the multiplication of two numbers. e.g. There are 3136 horses. Each horse has 4 legs. How many legs are there altogether?

Number of legs = 3136 × 4

Step 1: Multiply the thousands by 4.

4 x 3000 = 12000

Step 2: Multiply the hundreds by 4.

4 x 100 = 400

Step 3: Multiply the tens by 4.

4 x 30 = 120

Step 4: Multiply the ones by 4.

4 x 6 = 24

12000 + 400 + 120 + 24 = 12 544

 × 3 1 3 6 4 4 × 3000 1 2 0 0 0 4 × 100 4 0 0 4 × 30 1 2 0 4 × 6 2 4 1 2 5 4 4

So there are 12,544 legs altogether.
