ReplyDeleteBasic concept is not clear. Very cleverly ,he has done 9-7 and so the answer.
DeleteThe student is familiar with the concept that smaller number 7 can be subtracted from big number 9 but not the vice versa which can be explained through cards of 7 ones and 9 ones.
DeleteChild has confusion regarding numbers first I will make him understand from the basic. After that give some easy questions like 5-4 and so on then choose two digit number, so that he/she can handle it better
DeleteThe child has not understood the basic concept of subtraction.The concept can be taught through hands on activity and by using backward counting.
ReplyDeleteThe child has not understood place value.

ReplyDeleteThe child has not understood place value.Helping and making clear the number value will help better understanding
ReplyDeleteThe child has to be given more examples where he or she can do regrouping of numbers and get ample practice for simple and borrowing subtraction using beads of necklaces and bundles of sticks .
ReplyDeleteThe child has not understood place value. It can be taught through hand on activities.
ReplyDeleteTo make the child understand the concept of subtraction the numbers can be divided into boxes so that he can see & understand the tens (T) and ones (O) i.e. place values. It's important to make him understand the importance of place values. Now he must be taught the concept of borrowing to clear his concept instead of jumping directly onto the final answer.
ReplyDeleteThe child has done subtraction but without understanding the core concept. The child should be made to understand that a bigger number cannot be taken away from a smaller number. The child has to be given more examples where he or she can do regrouping of numbers and get ample practice for simple and borrowing subtraction using beads of necklaces and bundles of sticks .

students of different standard is familiar with the concept that smaller number 7 can be subtracted from big number 9 but not the vice versa which can be explained through cards of 7 ones and 9 ones.
ReplyDeleteIt shows that the child is familiar with subtraction of smaller one digit numbers from greater numbers but has not understood tens and ones place value correctly and Concept of borrowing in the form of tens. This will be cleared by giving bundle of ten and then opening it for solving the problem.
ReplyDeleteI think the child has not understood the rules to be followed for two digit subtraction, Moreover he has to know the borrowing part from the next immediate number. It has to be made understood by showing the rules and applying it with lots and lots of practice .
ReplyDeleteChild knows subtraction, to a limit, need to understand the concept of subtraction in a right way, following certain rules, through different activities and math games.
ReplyDeletechild does not understand the basic concept of subtration.
ReplyDeleteThe child has done this mistake as his concept of subtraction is not correct. He has to be given clear idea by doing with objects that 9 balls can not be taken out of 7 balls . For such situation he should also be guided to write the numbers in proper place with correct place value. The concept of borrowing can be developed in this way .
ReplyDeletehands on activity methods
ReplyDeleteConcept of borrowing is to be explained by telling the place value of numbers.
ReplyDeleteIt shows that the child has done subtraction but unable to understand the basic concepts. It is important to make him understand the concept of place value. Also hands on activities must be done in the class to make him understand the concepts.
ReplyDeleteWe can improve this problem by subtracting matchsticks or wooden stick or with some other attractive things for example some real apples etc.
ReplyDeletefor better mathematical communication ; learning can be related with resources used in daily life
ReplyDeleteconcept of place value along with hands on activities to be given to make the child understand the concept.
ReplyDeleteThe student is familiar with the concept that smaller number 7 can be subtracted from big number 9. Here concept of place value can be explained through cards of 7 ones and 9 ones.
ReplyDeleteNormally I suggest children to read the problem verbally.
ReplyDeleteHere when we read ir as subtract 9 from 12.
Or
Take away 9 objects from the available 17 .
With this type of oral drilling or reading the problem avoid mistakes in future also.
'_ ' this symbol minus belongs to 9.
Need to provide understanding of reading digits correctly.
Child can be taught through hand on activities.Actually learning can be related with resources used in daily life
ReplyDeleteThe child has done the subtraction with the understanding that a small number can be subtracted from a bigger number, hence 9-7=2. In the next step she or he has subtracted 1-0=1, therefore the answer 12. This shows that the child has not understood place value or regrouping of numbers. The teachers should first give ample examples and hands-on activities using beads/ flowers/ marbles/ buttons etc., to the students to clarify the concept of regrouping and place value of numbers. Then only these type of problems should be given to the students. Incomplete information and knowledge will lead to such faulty answers and there will be a learning gap in understanding the core concept of subtraction.
ReplyDeleteThe child has not able to grasp concept of smaller number and bigger number. S/he should know about the what come before/after to know about bigger and smaller number, then s/he can do the single digit subtraction by using concrete materials to clear the concept. Later on it can be moved on to two digits. The child should know about tens and ones also.
ReplyDeleteThe concept of subtraction can be made clear to the child by making him understand the box method where the ones and tens no. is written separately and made clear about subtraction method
ReplyDeleteThe student is familiar with the concept that smaller number 7 can be subtracted from big number 9 but not the vice versa which can be explained through cards of 7 ones and 9 ones.
ReplyDeleteCHILDREN HAVE TO BE FAMILIARIZED WITH THE CONCEPT OF SUBTRACTION ALONGE WITH VARIETY OF EXERCISES

Though the child understood What subtraction is but not clear with the place value concept. So, to make him/her clear, that the teacher can take either an example or first clear
the taught with the concept of borrowing of the number if the number is of smaller value.

ReplyDeleteConcept must be made clear to the child with lot of examples. the child should be taught the place value
ReplyDeleteDidn't understand subtraction properly, also number system properly.
ReplyDeletethe concept of place values and the concept of subtracting a smaller no from a bigger no in the top place have to be made clear. Concept of borrowing from tens place to ones place have to be made clear by giving lot of examples and good practice.
ReplyDeleteBasic concept of child is not clear that we should subtract small number from big number, he subtract 9-17 so the answer was 12. If he subtract in correct way he get correct answer.
ReplyDeleteActivity - We should give them some beads to subtract. Then he will know concept
Anju The child is taught subtraction without starting the concept using concrete objects and without correlating with daily life situations. It shows the child forgot the rules of subtraction and made the mistake.
ReplyDeleteIt has to be taught using hands on activities based on classification like what is taken and what is left in the group
Child has subtracted smaller number from larger number and forgot digital place understanding. Teacher has to explain with activity, the concept of larger and smaller number. Subtraction is taking away some part from whole part. classification, grouping of articles, can help him in learning subtraction.
ReplyDeletechild understanding of the concept of subtraction the numbers can be made by dividing to boxes so that he can see & understand the tens (T) and ones (O) i.e. place values. It's important to make him understand the importance of place values. Now he must be taught the concept of borrowing to clear his concept instead of jumping directly onto the final answer.
ReplyDeleteChild doesn't understand the concept of place Value.
ReplyDeletehe does't understand that small number is subtracted from big number. he just subtracted fast.
ReplyDeleteFirst I will help him to arrange the numbers in column . So , the child can see the places of digits. Then, I will help him to start subtraction from the ones place, I will explain him we cabt subtract a big digit from a small one. So we have to borrow.
ReplyDeleteOr I will suggest him to do backward counting .

It tells us that child has not understood the concept. For such children, subtraction concept should be made clear using objects.
ReplyDeleteChild must be told concept of place value. He should think 17 as 10 +7 instead of 1 and 7 separately.
ReplyDeleteChild don't know place value and concept of basic operation subtraction so he think 17as10+7 instead of 1and7 separately , child should made clear subtraction concept by using objects
ReplyDeleteChild must be told concept of place value. He should think 17 as 10 +7 instead of 1 and 7 separately.
