# Write a multiplication story with the factors 2 and 5

This page includes Number Worksheets such as counting charts, representing, comparing and ordering numbers worksheets, and worksheets on expanded form, written numbers, scientific numbers, Roman numerals, factors, exponents, and binary numbers. There are literally hundreds of number worksheets meant to help students develop their understanding of numeration and number sense. In the first few sections, there are some general use printables that can be used in a variety of situations. Hundred charts, for example, can be used for counting, but they can just as easily be used for learning decimal hundredths. Tell students that today they will begin learning about multiplication. Tell students that multiplication can be thought of as repeated addition of equal groups. Explain this in the context of your example: This problem can be read as 4 groups of 3.

Explain that in this equation, the numbers 4 and 3 are each known as a factor. Define factors as the numbers we can multiply together to get another number.

 Multiplication Worksheets | Free , Easier to Grade , Customizable - CommonCoreSheets The multiples of 7 are 7, 14, 21, 28, 35, 42, 49, 56, How do you write a multiplication story with the factors 2 and 5 In other countries that use a comma as a decimal mark, either the period or a middle dot is used for multiplication. This implicit usage of multiplication can cause ambiguity when the concatenated variables happen to match the name of another variable, when a variable name in front of a parenthesis can be confused with a function name, or in the correct determination of the order of operations. Grade 2 Math Worksheets - Multiplication tables of 2, 5 and 10 | K5 Learning Write a muliiplication story with the factors 2 and 5 2 people found this useful What is the multiple of 2 and 5 and 3? The LCM, or lowest common multiple, of 2, 5, and 3 is

Draw 4 circles and put 3 dots in each circle, to illustrate 4 groups of 3. Count each of the dots as a class. Once you're finished, write the entire equation on the board: Explain to your class that multiplication problems can be represented as repeated addition of the same number.

Using the white board, join the circles you drew with plus signs, and write an addition equation that matches your example multiplication problem. Discuss the benefits of multiplication as opposed to addition with your students. Some questions to ask include: Why do we multiply?

When would it be easier to multiply instead of adding? Give an example to show when multiplication is easier than addition. Guide students in their thinking by asking, Which problem do you think would be faster to solve?

Tell students that they will be using candy to figure out multiplication problems today. Using an interactive whiteboard, document camera, or projector, display the Candy Math Recording Sheet to the class. Discuss the example on the Recording sheet. Next, project the Equal Groups worksheet.

Draw dots or candies to model solving the example problem for your students. Write an example multiplication problem on the board, such as 4 x 5.

Tell your students to make 4 groups of 5 by putting 5 candies each into 4 circles. Ask students to solve the equation by counting how many total candies they used.

Once students have the answer, challenge them to solve this multiplication problem using repeated addition. To do this, they must count how many candies are in each circle, and add those numbers together. Guide students to write this information on their worksheet.

Check to make sure students understand the relationship between multiplication, equal groups, and repeated addition by asking questions such as: How are multiplication and addition related?

How can we use equal groups to solve a multiplication problem? Independent working time 20 minutes On the board write five more multiplication problems that students can work on at their own pace. Circulate around the classroom as students are working to monitor accuracy.

Ask students if they see a relationship in the problems that they solved. Do they see any products that are the same?

## Respond to this Question

Students should be able to determine that 3 x 6 and 6 x 3 have the same product. Let students know that this is known as the commutative property of multiplication. Challenge students to figure out if this always works in multiplication. If we switch factors, will the product remain the same?

## Multiply These Numbers...

Give students a few problems to try this with, such as:Then, on a sheet of paper write a repeated addition equation and a multiplication equation to go with the model you built (i.e. 6 + 6 = 12 and 2 x 6 = 12) Hand out six paper plates, two dice, 36 linker cubes, and a sheet of paper to each pair of students.

A factor pair refers to a set of two numbers, which when multiplied result in a definite number. The Complete K-5 Math Learning Program Built for Your Child Parents, Get Started for Free.
