Multiply by 3

 Multiplication is adding the same number repeatedly.

 To multiply by 3, you add a number to itself 3 times.

What’s 2 × 3?

You can draw equal groups to help figure it out.

2 × 3 is a shortcut for writing:

2 + 2 + 2 = 6

Tip: Do skip-counting in your head to figure it out:

2, 4, 6

  • 11 × 10 = 110
  • 12 × 10 = 120

💡 Multiplying a number by 10 is the same as adding a number to itself 10 times.

3 x 10 = ?

To figure out the answer, we can do repeated addition:

3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 =30 😅

Learn with an example

Multiply to find the products. Is each product less than 12, equal to 12, or greater than 12?

Place each expression into the correct box.

  • 10 x 4
  • 4 x 5
  • 5 x 5

Look at one expression at a time.

Multiply to find the product of each expression. Then, compare the product to 12.

10 x 4

The expression 10×4 means 10 groups of 4.

4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 40

10 × 4 = 40

10 ×4 belongs in the less than 12 boxes.

4 × 5

The expression 4×5 means 4 groups of 5.

5 + 5 + 5 + 5 = 20

4 × 5 = 20

4 × 5 belongs in the greater than 12 box.

5 x 5

The expression 5×5 means 5 groups of 5.

5 + 5 + 5 + 5+ 5 = 25

5 x 5 = 25

5 × 5 belongs in the greater than 12 box.

Place each expression into the correct box.

Multiply to find the products. Is each product less than 10, equal to 10, or greater than 10?

Place each expression into the correct box.

  • 10 x 1
  • 5 x 5
  • 3 x 2

Look at one expression at a time.

Multiply to find the product of each expression. Then, compare the product to 10.

10 × 1

The expression 10×1 means 10 groups of 1.

1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 10

Place each expression into the correct box.

  • 10 x 3
  • 10 x 4
  • 10 x 5

Look at one expression at a time.

Multiply to find the product of each expression. Then, compare the product to 45.

10×3
