We know bill is a slip of paper on which a shopkeeper notes down the requirements of a buyer. To estimate the product, we first round off the multiplier and the multiplicand to the nearest tens, hundreds, or thousands and then multiply the rounded numbers.
Estimating products by rounding numbers to the nearest ten, hundred, thousand etc. In 4th grade worksheet on word problems on addition and subtraction, all grade students can practice the questions on word problems based on addition and subtraction. This exercise sheet on. For estimating sums and differences in the number we use the rounded numbers for estimations to its nearest tens, hundred, and thousand.
In many practical calculations, only an approximation is required rather than an exact answer. To do this, numbers are rounded off to a. In the worksheet on forming numbers with digits, the questions will help us to practice how to form different types of smallest and greatest numbers using different digits. We know that all the numbers are formed with the digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. In worksheets on comparison of numbers students can practice the questions for fourth grade to compare numbers.
This worksheet contains questions on numbers like to find the greatest number, arranging the numbers etc…. Find the greatest number:. The position of the digit at the extreme left of a number increases its place value.
So the greatest digit should be placed at the. A number which is a multiple of 2 is an even number and that which is not multiple of 2 is an odd number. All those numbers that can be put into pairs are called even numbers, that is, all those numbers which come in the table of two are even numbers.
The number that comes just before a number is called the predecessor. So, the predecessor of a given number is 1 less than the given number. Successor of a given number is 1 more than the given number. For example, 9,99,99, is predecessor of 10,00,00, or we can also.

Comparing Division and Multiplication In order to teach division, it usually helps to start with multiplication. Dividend vs. The Standard Algorithm for Division As students master their basic division facts, the need will arise for students to learn how to divide larger dividends. Lesson 1: Introducing the Concept of Division As with addition, subtraction, and multiplication, students practice strategies and algorithms that allow them to perform operations beyond basic facts.
Materials: Base-ten blocks that all students can see for example, with an overhead projector ; base-ten blocks that students can use Preparation: Be sure to provide at least one set of base-ten blocks for each pair of students.
The 54 represents the total number of items you begin with. The 9 represents how many items are in each group. The quotient is 6. It is the quotient, but more importantly, the 6 represents the number of groups you will divide the 54 items into groups to have 9 items in each group. The quotient, or number of groups, is written above the Ask: Let's try another problem now.
The 68 represents the total number of items you begin with. The 4 represents how many items are in each group. Since this is not a basic division fact, it is unlikely that students will be able to find a correct quotient. If students do think they know the quotient, have them share their thinking. Compare strategies, and share that one common strategy for performing more complicated division with multi-digit numbers is using the standard algorithm.
Say: When we are dividing numbers too large for us to immediately know the answer to, it is best to do the problem in several small parts.
Say: When completing the long division expression "68 divided by 4," remember that 68 is 6 tens and 8 ones. Show 6 tens so that the entire class can see them. Ask: How many equal groups of 4 tens can you make?
You can make 1 group that will contain 4 tens. Say: Since you can make only 1 group, you write a 1 over the tens place in Say: Since you cannot make additional groups containing four tens, you will need to regroup the remaining 2 for 20 ones.
Show 2 tens being regrouped as 20 ones so that the entire class can see. Next, combine the 20 ones with the 8 ones. Ask: If we combine the 20 ones with the 8 ones, how many ones will we have? Ask: How many groups with 4 ones in each group can we make from the 28 ones? We can make 7 groups with 4 ones in each group.
Say: Since 7 groups of 4 ones can be made, we write 7 above the ones place in Say: Since there are no ones remaining, our quotient is If we make 17 groups with 4 items in each group, we should have a total of 68 items. Have students individually or in pairs make 17 groups with 4 items in each group.
Then have them count the total number of items to see if there are indeed Continue this activity using slightly larger numbers. Have the students use their base-ten blocks to determine the place value for the quotient. Remember to always have the students check their work using their base-ten blocks.
Lesson 2: Developing the Concept of Division After using manipulatives to introduce the division algorithm for multi-digit numbers, it's time to develop the concept more fully. Ask: How can we write divided by 6? Ask: Which notation will you use to find the quotient of divided by 6?
Direct students to use the long division expression to enable them to use the division algorithm. Say: Use your base-ten blocks to represent Ask: Let's begin with the hundreds. Since we are dividing by 6, we need to make groups containing 6 hundreds.
