Activity 5: Share Your Thoughts
A child, when asked to subtract 17-9, wrote 12 as an answer. What does this tell you about the child's thinking and how will you help the learner better understand the concept of subtraction? Share your thoughts.
When doing a subtraction problem, it's important to be able to properly label and...
ReplyDeleteThe child is unable to comprehend the idea of substraction hence he/she should be taught more about the concept of substraction for better understanding
ReplyDeleteThe concept of substraction is not clearly learnt by the child.
ReplyDeleteI would teach the child that substraction is taking out from the whole and finding out the remaining, using some concrete objects like pebbles or toffies.
Clearly, the child doesn't understand the concept of subtraction by borrowing method.
ReplyDeleteThe first step is to teach the child how to arrange digits starting from ones place for the operation to begin. Then, to borrow "one" from the tens place to make it bigger than the digit to be subtracted. This way the subtraction process can go on smoothly without confusing the child.
I would help the child to learn a concept of subtraction with the help of pictures and activities. This way the subtraction facts can be visualised with more practice.
ReplyDeleteFirst of all the child need to understand the concept of subtraction.And we can easily teach him by drawing an object on the board and then ask him to subtract it.
ReplyDeleteThe child doesn't understand the concept or meaning of subtraction. I will help the student that subtraction can mean taking away or finding the difference. For example, 17-9 can mean how many are left when you take 9 from 17? Or 17-9 can be interpreted as how much more is 17 than 9? The answer will be 8. A subtraction is opposite to addition.
ReplyDelete17-9=8
9+8=17.
The concept of Substaction of single digit number and two or more digit numbers is confused by the child. Generally a teacher started explaining Substaction as from bigger number substract smaller numbers. That is our mistake. So we needs to clarify these concept in single digit numbers or other digits numbers. By using age old technique drawing small lines and cutting for substracted numbers, we can make them to understand easily.
ReplyDeleteThe child substract 7 from 9 and take down 1 which give the result 12.
ReplyDeleteHere the child did not understand the concept of substraction properly.
The child can be help to understand the concept of substraction by applying story method or activity using objects etc.
I appreciate that the child have sharp brain but to follow the right path in subtraction, l should use manipulatives Or stones for the child hands on experience so that His/her understanding will also helps him/her in visualising the concept.
ReplyDeleteThe child subtract 7 from 9 and take down 1 which give the result 12. Here, the child did not understand the concept of subtraction properly. The child can be help to understand the concept of subtraction by drawing small lines and cutting for subtracted numbers.
ReplyDeleteThe child does not understand the concept of subtraction of Bigger numbers from a smaller number by borrowing from the tens place .We should teach accordingly orby activity that how much is there by taking away 9 from 17 pebbles or marbles like this. And subtraction is the opposite of addition 17-9=8 and 8+9=17.
DeleteFirst the child need to know the number and then slowly learn how to subtract or addition.so different subtraction mode need to be taught for the child to know the subtraction easier.
ReplyDeleteThe child must be first taught what substraction is and how substraction is done showing some demonstration only then will they understand what substraction is all about and help them in solving a problem
ReplyDeleteIt shows that the child hasn't understand the idea of Subtraction and re-teach them about subtraction again
ReplyDeleteThe child might thought that 9 is greater than 7 of 17 so 7 is subtracted from 9 and found the result as 12.
ReplyDeleteIt is because of the fact that-
1.the child doesn't know the place value.
2.the child don't know the concept /steps to be followed for subtraction.
Therefore, first I would try to clear above mentioned steps. Then surely the child can proceed the subtraction easily.
The concept of substraction is not clearly learnt by the child and not clearly understand.
ReplyDeleteChildren need to know clearly about Place value and face value concept. And teach about comparison between numbers, etc.to the children.
The child doesn't have the clear concept of subtraction, mainly the idea of subtraction from a two digit number. So, i as a teacher will try to make her understand the concept of digits and subtraction practically using things like matchsticks. I will keep 1 digit and 2 digit number sticks and their places. Ones place and tens place bundle, and practically tens place bundle will be broken and take out the necessary number of sticks so that she will catch the idea.Thus, she will understand the concept.
ReplyDeleteThe child is not able to understand the concept of subtraction, activity base learning can enhance the child's understanding like giving him 17 marbles asking him to give away 9 to his friend and count how many is left with him.such activity will make students enjoy and learn better.
ReplyDeleteThis is a classic example of a child not understanding the concept of unit place and mathematical symbols. In this case, the first step to make the child understands the concept of unit place and gradually progress to higher mathematical concepts such as "addition," subtraction," multiplication," etc. This whole process should be done in the child's mother language so that the concept is driven home much faster to the child. Different pedagogies can be used to teach the child but the most appropriate one is when the child learn these concepts by using hands-on materials that are easily available in the class as well as at home and also encouraging parents to instill these mathematical concepts in a playful manner at home. This is the best way to teach a child mathematics using the natural environment as a tool.

The concept of subtraction is not clear to the student.we should tell that the subtraction is always done from bigger number to smaller number..

ReplyDeleteThe child may not clearly understand the concept and the process of substraction. So, I can help the learner better understand the concept of substraction by providing hands-on experience, use of toys and manipulative and collaborative learning.

ReplyDeleteIn such cases the numbers should properly arranged or labelled so as to avoid the mistakes.
ReplyDeleteFirst,we have to let the students learn and know numbers and the basic of it properly and then comes the concept of substraction.
ReplyDeleteIn this case we should teach the rule of subtraction gently and I also learn when I was a child by drawing the line of no. and cut the line that's style of learning was so helpful in addition and subtraction.
ReplyDeleteThis shows that the Child's don't understand or know how subtractions works,So I'll make him/her understood subtractions by letting him/her counting his/her fingers or by writing 1 to 17 and make him/her erase 9 from it by teaching this way I believe that he/she will understand how subtractions works.
ReplyDeleteIt shows how the child hot confused with the numbers provided and his concept is not very clear. So I would carefully explain and experiment with the child hand in hand and show him how to get it done. N his confusion about the larger or smaller number also will be explained.
ReplyDeleteThe child here is unable to perform subtraction that means the child has not properly understood the concept. In order to make the child understand , several activities which includes blocks,pens or any easily accessible things can be used to clear the concept of subtraction starting from small number and gradually proceeding to bigger ones.
ReplyDeleteThe concept of substraction is not clearly learnt by the child.
ReplyDeleteI would teach the child that substraction is taking out from the whole and finding out the remaining, using some concrete objects like pebbles.
Since the child is not able to understand what is substraction, it is necessary to first make the child understand the basic meaning of substraction, not from the textbook, by using toys, blocks, pencils or Candies etc to remove or separate each pieces from the group and count the remaining. This may sound like a play but it will help the child learn the basic concept better with less pressure.
ReplyDeleteI would help the children to find out what is left when taking one number away from another with the help of materials which will be shown to them.
ReplyDeleteirst of all the child need to understand the concept of subtraction.And we can easily teach him by drawing an object on the board and then ask him to subtract it.
ReplyDeleteThe child did not understand the concept. First we need to make him understand the meaning of subtraction and the easy way is by teaching him to draw an object and ask him to erase or subtract it.
ReplyDeleteThis shows that the child do not understand how to arrange the numbers in order to substract. Hence, making the child to understand this concept properly will solve his problem
ReplyDeleteThe child does not have the concept of position and value of the numbers, so thinking that 9 is more than 7, the child subtracted 7 from 9 to get 2 and wrote 12
ReplyDelete9
(-)17
12
We have to teach children the number sense, groups of tens and comparison of numbers like bigger than/smaller than, etc.
Give them problem solving situations involving combination, taking away, equal distribution of objects, more than, less than etc.
We should also provide opportunity of attempting different ways of solving problems and ultimately reaching to problem solving.
Teaching the child how to arrange the numbers for substraction may solve the problem
ReplyDeleteThe child does not have the concept of place value and values of numbers 7in 17 and 9. I should tell that face value is less important in subtraction For better understanding I would use some concrete objects like toffee by giving 17 toffees and taking out9 toffees.How many toffee are left?
ReplyDeleteThe child is not having the conceptcof substraction. He just subtract smaller digit from larger digit. Concept of minuend and subtrahend was blank. The minuend, subtrahend and difference are parts of a subtraction problem.
ReplyDeleteIn the subtraction problem, 17 – 9 = 8 the number 17 is the minuend, the number 9 is the subtrahend and the number 8 is the difference.
To make child understand properly first he should be taught by giving 17 marvels and ask to give me 9 out of it. By doing this he will surely understand his mistake. And we should teach him the very concept of number as base 10 system.
I would like to make them understand the concept of subtraction, and teach them starting from one digit number, e.g, 9-7=2

Despite the emphasis in school on memorizing the basic addition and subtraction facts, child's typically rely on informal counting procedures to do basic arithmetic because, initially,that in more meaningful. Child's difficulties in substraction appears to be due, in part, to difficulties with their informal approach. Moreover, difficulties at the informal level may hinder the development of more advanced procedures such as reasoning out facts or recalling facts.
ReplyDeleteIt shows that the child does not know the concept of place the value and the face value of a digit clearly and also the concept of subtraction.
ReplyDeleteI must teach the child both the concepts clearly using balls/sticks/pebbles whatever available.
In this case the child is knowing the knowledge of one's place n ten's place so I will try to understand them first about this and then place value and face value. Then I will teach them substractions of one digit numbers and two digit numbers.
ReplyDeleteThe child seems to be familiar with subtraction as the process of taking away a number from another and it is the method of calculating the difference between two numbers But the child is apparently unclear about the concept of subtraction and unfamiliar with the operation of subtraction.
ReplyDeleteThe child also needs clarity on the knowledge of place value and concept of borrowing in subtraction.
Once the problem has been identified the child's doubts can be cleared through proper introduction to the terms and operation of subtraction as while solving subtraction problems, one-digit numbers can be subtracted in a simple way, but for larger numbers, we split the numbers into columns using their respective place values, like Ones, Tens, Hundreds, Thousands, and so on. While solving such problems we may encounter some cases with borrowing and some without borrowing.
Another simple and playful method can be employed while subtraction of small numbers, like giving the child 17 marbles asking the child to count 9 marbles out of it and hand it out to the teacher. Then ask them to count what is left and write the result as result of subtracting 9 from 17.
The kid looks like he is not able to think of the correct result that will come out if he/she subtracts 9 from 17, so I will teach him/her about the concept and rules of subtraction and addition. If he/she still doesn't understand fully or properly, I will move to the practical stage and use objects for better sense of view and understanding.
ReplyDeleteWe all know that our students all learn differently, what works for one student may not be what is going to work for the student sitting next to them. By equipping your students with a variety of ways to solve subtraction problems, you are setting them up for success.
ReplyDeleteOne main factor in the teaching of different subtraction strategies is that students get into the habit of verbally explaining how they got their answer.
Children often struggle to grasp the formal concept of subtraction. When teaching students how to subtract, it can be helpful to present the concept to them in a variety of formats. After introducing basic subtraction principles, tackle place values and two-digit subtraction. Try different techniques to see what works for your student(s). As they strive to master subtraction, supply your students with several ways of solving subtraction problems, such as the Common Core’s measurement method or the think-addition method.
ReplyDeleteThe child does not understand the concept of subtraction. The child is needed to make understand the meaning of subtraction. Here as a teacher first of all have to explain the literal meaning of it , next we have to teach the approaches to solve it .
ReplyDelete17-9=12 is wrong
ReplyDelete17
- 9
........
8 The student does not understand placing of unit's place and one's place and subtracting from the unit's place by a unit's place no.
The wrong answer of 17-9= '12' tells me something about the child that is the child does not know/ understand the operations of addition and subtraction that are complementary to each other.
ReplyDeleteAddition is a combination/aggregation of distinct sets of like entities while SUBTRACTION is the exact opposite that is take away or left over from a set of elements.
These operations are not just to develop computational abilities in children but to use them as tools for problem solving in daily life context.
This shows that the child has not yet completely familiarised with the concept of substraction.Children often struggle to grasp the formal concept of substraction.when teaching students how to substract, it can be helpful to present the concept to them in a variety of formats. After introducing basic substraction principles, tackle place values and two-digit substraction.we can try different techniques to see what works best for the students.
ReplyDeleteI would help the child to learn the basic of substraction by the help of pictures or by letting them to count with their fingers.
ReplyDeleteFirst of all, the child doesn't understand the concept of subtraction by borrowing method.
ReplyDeleteThe first step is to teach the child how to arrange digits starting from ones place for the operation to begin. Then, to borrow "one" from the tens place to make it bigger than the digit to be subtracted. This way the subtraction process can go on smoothly without confusing by the child.
The child is thinking about subtraction is from greater number so we should make the child know more about the concept of subtraction
ReplyDeleteThe child does not clearly understand the concept of subtraction. At first, I would try to make the child understand the basics of subtraction using pictures and real objects. After the child gets familiar with the operation, I would move on to further explain the process while only using numbers.
ReplyDeleteFirst I would like to ask the student to collect 17 small bamboo sticks and ask him or her to drop 9 sticks. Then I would like him/her to count the remaining sticks in his/her and I will ask the result (answer)
