In this quiz, students will add two numbers in order find the sum. After finding the sum, round it up to the nearest ten. For example, 7 + 4 = 11, however, if rounded to the nearest ten, the expected answer is 10. Children taking this quiz have to watch out for this caveat else the response will always seem incorrect. Hence the kid gets an opportunity to practice more on the concepts of estimating and adding the numbers. While attempting the questions in this quiz, the child also gets a good practice on how to round off the numbers.

How to add and estimate number to nearest 10?

Adding and estimating numbers is a great way to get a rough idea of the answer to a math problem without having to do the exact calculation. In this case, we’re going to talk about adding and estimating to the nearest ten.

When we add numbers to the nearest ten, we are focusing on the number in the tens place. For example, let’s say we want to add the numbers 12 and 34. To add these numbers to the nearest ten, we would round each number up or down to the nearest ten. So, 12 would round down to 10 and 34 would round up to 40. Now we can add the numbers 10 and 40 to get 50.

Estimating can be helpful when working with large numbers and you want a rough idea of the answer. For example, if you want to estimate the sum of 17 + 29, you can round 17 to 20 and 29 to 30, Now you can add 20 + 30 = 50 which gives you a rough idea of the answer to the problem.

To estimate a subtraction problem, you can use the same method of rounding to the nearest ten. For example, if you want to estimate the difference between 47 and 19, you can round 47 to 50 and 19 to 20. Now you can subtract 50 – 20 = 30 which gives you a rough idea of the answer to the problem.

We can also estimate when we multiply numbers by finding a rough idea of the answer by rounding the number to the nearest ten or hundred and then multiplying.For example, if we have to multiply 27 and 34, we can round 27 to 30 and 34 to 30 and then multiply 30*30=900.

It’s also helpful when you are dealing with large numbers, for example, if you have to multiply 678 and 342, instead of solving the exact calculation, we can estimate 678 to 700, and 342 to 340, now you have 700*340= 238,000 which gives you a rough idea of the answer.

Estimating can also help you check your work when you’re solving a math problem. For example, if you’re solving a problem and your answer is about 300, but you estimate that the answer should be closer to 200, you’ll know that you’ve made a mistake somewhere.

In summary, adding and estimating numbers to the nearest ten is a great way to get a rough idea of the answer to a math problem. It’s especially helpful when working with large numbers. To add or estimate numbers to the nearest ten, we round each number up or down to the nearest ten and then perform the calculation. This method can be used for addition, subtraction, and multiplication. Estimating can also help you check your work to make sure you’ve done the problem correctly.
