A key way to teach multiplication is via multiplication sentences. Unlike a traditional sentence, multiplication sentences use numbers and symbols to express a statement.

Relating Multiplication and Division: Overview An arrangement of objects, pictures, or numbers in columns and rows is called an array. Your students used arrays earlier to multiply. In this chapter your students will learn how to use arrays to show the relationship between multiplication and division.

Students will learn that division can be thought of in two ways, partitioning and measurement. Although at this level students may not use these names, you can convey the meaning of both kinds of division so that they can have a better understanding of the division process.

When you divide to find the number of objects in each group, the division is called fair sharing or partitioning. A farmer is filling baskets of apples. The farmer has 24 apples and write a division sentence baskets.

If she divides them equally, how many apples will she put in each basket? When you divide to find the number of groups, the division is called measuring or repeated subtraction.

It is easy to see that you can keep subtracting 4 from 24 until you reach zero. Each 4 you subtract is a group or basket. A farmer has 24 apples.

How many baskets of 4 can she fill?

Manipulatives and visual aids are important when teaching multiplication and division. Students have used arrays to illustrate the multiplication process. Arrays can also illustrate division. Since division is the inverse, or opposite, of multiplication, you can use arrays to help students understand how multiplication and division are related.

If in multiplication we find the product of two factors, in division we find the missing factor if the other factor and the product are known. In the multiplication model below, you multiply to find the number of counters in all.

In the division model you divide to find the number of counters in each group. The same three numbers are used. So when multiplying or dividing, students can use a fact from the inverse operation.

Students can also check their work by using the inverse operation. Notice that the numbers in multiplication and division sentences have special names. In multiplication the numbers you multiply are called factors; the answer is called the product.

In division the number being divided is the dividend, the number that divides it is the divisor, and the answer is the quotient. Discuss the relationship of these numbers as you explain how multiplication and division are related. There are other models your students can use to explore the relationship between multiplication and division.

Expose your students to the different models and let each student choose which model is most helpful to him or her. Here is an example using counters to multiply and divide.Division (Basic) Division (Long Division) Fractions.

Geometry. Graphing. Hundreds Charts. Building Sentences (Basic) On each worksheet, students cut out word cards and rearrange them to make a sentence. This is a blank template for a three-word build-a-sentence activity. The teacher can write her own mixed-up sentence for students to.

Mar 19, · =15 = 10 = 5 = 0 Write the division sentence. This is a 3rd grade math question for my cousins homework. My aunt & I are stumped & feeling really stupid!!Status: Resolved.

Notice that the numbers in multiplication and division sentences have special names. In multiplication the numbers you multiply are called factors ; the answer is called the product. In division the number being divided is the dividend, the number that divides it is the divisor, and the answer is the quotient.

a) In the diagram there are three groups each containing six dots and the total. number of dots is 18, So the division equation which answers the question “How many groups ” is.

How to write a division sentence. Division: One of the four major mathematical operations is division. This is a process in which a whole number is broken down into smaller, even parts. It is. In composition and academic writing, a thesis statement (or controlling idea) is a sentence in an essay, report, research paper, or speech that identifies the main idea and/or central purpose of the nationwidesecretarial.com rhetoric, a claim is similar to a thesis.
