Working with number sentences in the classroom At any time in Key Stage 1 or 2, teachers may show children a word problem and then ask them to write the number sentence that goes with it, for example: These arrangements all have something in common; they are all in rows and columns.

A number sentence is an arrangement of numbers and symbols, such as the following: It can also be described as a 4 by 3 array. This is called the Commutative Property of Multiplication. A teacher may then ask children to find as many other possibilities as they can.

Have a volunteer label the factors and product and read them aloud with the class. Most students should remember that changing the order of the addends does not change the sum.

For example, they can picture students in a marching band arranged in equal rows or chairs set up in rows in an auditorium. The answer is called the product. It is a 5 by 4 array. In Year 2, children start to write number sentences for multiplication and division, so they need to understand the symbols: An arrangement of objects, pictures, or numbers in columns and rows is called an array.

Students should be familiar with the Commutative Property because it also applies to addition. The numbers that are multiplied are called factors. The answer is called the product.

Using Arrays to Show Multiplication Concepts: Students should realize that the product stayed the same. The order of the factors changed, but the product stayed the same.

Remind them that the array was turned on its side, so the number of squares is still In Key Stage 1 they may come across something like this: They studied the Commutative Property of Addition earlier. When equal groups are arranged in equal rows, an array is formed.

Here, it may be a good idea to try a number out in the first gap, for example, Overview Students can more readily develop an understanding of multiplication concepts if they see visual representations of the computation process.

Look at this example. Then have them use arrays to model the Commutative Property of Multiplication. The numbers in multiplication sentences have special names. Changing the order of the factors in any multiplication sentence does not change the product.

Students should know how to use arrays to multiply. With what other operation have you used the Commutative Property? Look at the multiplication sentence that describes the array below.

What is a number sentence?

The numbers in multiplication sentences have special names. Children start learning how to write addition and subtraction number sentences in Year 1.

Number sentence

4 5. Just as the name suggests, an inequality is a number sentence that shows how parts of a number sentence are unequal. For example, we know that 4 + 5 and 4 + 6 are unequal, so we couldn't say 4 + 5. 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. Practice math problems like Double Facts within 10 with interactive online worksheets for 1st Graders.
