Using a Multiplication Diagram

• Multiplication is similar to addition.
• In multiplication, you are adding the same
  number several times.
• For example
• 4 x 6 is the same as 444444 or 6666
• To help you organize your problems, you can
  use a multiplication diagram.

The diagrams or pictures you have created are
called arrays. Arrays are diagrams of groups of
equal numbers.
29
Arrays

• An array is a group of objects placed in
  rows and columns. Each row has the same number of
  objects and each column has the same number of
  objects.
• Arrays help us visualize multiplication
  problems. You can draw arrays to solve
  multiplication problems.

Because of the turn-around rule, you can arrange
the array two ways
