A key way to teach multiplication is via multiplication sentences.

Using Arrays to Show Multiplication Concepts: Overview Students can more readily develop an understanding of multiplication concepts if they see visual representations of the computation process. For example, they can picture students in a marching band arranged in equal rows or chairs set up in rows in an auditorium.

These arrangements all have something in common; they are all in rows and columns. An arrangement of objects, pictures, or numbers in columns and rows is called an array.

Arrays are useful representations of multiplication concepts. This array has 4 rows and 3 columns. It can also be described as a 4 by 3 array.

This array has 5 rows and 4 columns. It is a 5 by 4 array.

Notice that the rows in each array are equal. Think of the rows as equal groups.

Your students used equal groups to multiply in second grade. Look at this example.

When equal groups are arranged in equal rows, an array is formed. When you show students the connection between equal groups and arrays, students can easily understand how to use arrays to multiply.

They will use arrays again later to divide. Look at the multiplication sentence that describes the array below. The numbers in multiplication sentences have special names. The numbers that are multiplied are called factors. The answer is called the product.

Now look at what happens to the factors and product in the multiplication sentence when the array is turned on its side. The order of the factors changed, but the product stayed the same.

When the order of the factors in any multiplication sentence changes, the product does not change. This is called the Commutative Property of Multiplication. Students should be familiar with the Commutative Property because it also applies to addition.

They studied the Commutative Property of Addition earlier. See Addition and Subtraction. Help students realize that by applying the Commutative Property, they know twice as many multiplication facts.Writing Prompts.

Writing Multiplication Stories Example 1 You can write a multiplication story to show a multiplication problem.

There are various exciting exercises like picture multiplication, repeated addition, missing factors, comparing quantities, forming the products and lots more! Multiplication word problems are one of the more challenging applied math topics for grade school children to understand.

The language used for a multiplication word problem can be . Each column must contain the same number of objects as the other columns, and each row must have the same number as the other rows.

The following array, consisting of four columns and three rows, could be used to represent the number sentence 3 x 4 = 12, 4 x 3 =12, 3 + 3 + 3 + 3 = 12 and 4 + 4 + 4 = As well as modelling with equipment, students should write the same equation using repeated addition and using multiplication.

For example: 4 + 4 + 4 + 4 + 4 + 4 + 4 = 28 or 7 x 4 = Now ask the students to make up word problems using the problem structure above with different answers.
