DeleteChildren always get confused when it comes to subtract big number from small number.at this stage borrow should be introduced to them.
DeleteTo make the concept more clear subtraction with concrete objects should be taught at this stage first.
DeleteConcept should be made clear to the student by using real life objects surrounding them.
Deleteby using real shapes and objects conceptual teaching must be done
DeleteThe child's answer, 12, suggests a possible misunderstanding of the concept of subtraction. To help the learner, I would use visual aids like number lines, base-ten blocks, or counting cubes to demonstrate the concept of subtraction as "taking away." I would also provide opportunities for the child to practice subtraction with real-life scenarios and simple math problems, gradually increasing the difficulty level.
DeleteThe child has the conception that only lesser number can be sustracted from the greater number.tge concept of borrowing from tens or hundreds place is to be .made clear to the children by various activities
ReplyDeleteFoundation Numeracy
ReplyDeleteChild should be clarified the concept of borrowing.
ReplyDeleteGood one
Deletethe child is doing reverse subtraction. in stead of minusing 9 from 7, child is minusing 7 from 9. concept of borrowing is not clear
ReplyDeleteMay be the child has not understood the concept of borrowing used in subtraction.
ReplyDeleteChild has applied his previous knowledge wherein he/she was taught to subtract smaller digit from bigger.
ReplyDeletechild lacks in seeing place value and digit together ... for understanding concept of place value needs to be cleared first
The child misplaced the numbers.May be the child doesn't know the concept of borrowing.
ReplyDeleteI will try to make child understand subtraction concept with simple methods..Methods like counting with pebbles and sweets..
ReplyDeleteWill make child understand subtraction and concept with simple method
ReplyDeleteThe child may not understand we must put efforts
ReplyDeleteThe child miss placed the number may be the child doesn't know the concept of borrowing
ReplyDeleteI will make the child to understand the easy method of concepts and subtraction
ReplyDeleteEasy method to teach and learn
ReplyDeleteConcept of tens and ones also making groups of tens and ones
DeleteThere should be easy methods to teach children
ReplyDeleteMore drilling required
ReplyDeleteIf the child understands that concept well, he cannot make an error
ReplyDeleteBy give and take method.
ReplyDeleteSubtraction can be ease by foundation numeracy and explaining the concept in different ways as per child's understanding.
ReplyDeleteExplaining the conception in a proper way we can create the environment for child's understanding
ReplyDeleteThe child has not understood the concept of borrowing. But only knows to subtract small number from big number. That has to explained properly and in simple manner to the child.
ReplyDeleteWill revisit teaching learning experience on borrowing concept aby repetition of previous teaching method or with new activity/method
ReplyDeleteReverse subtraction is the issue here. With proper guidance and support child will understand.
ReplyDeleteThe child should know that one should subtract a smaller number from a bigger one.
ReplyDeleteExperiential learning should be given to children.
Student needs go learn subtraction of bigger number from smaller number
DeleteGive the child 17 one rupee coins and ask to give up 9 coins to you. Now ask the child how many coins left with him?
ReplyDeleteThere can be different possibilities
ReplyDeleteLike the child is adding in 12till he gets the bigger number 17 .
Child is doing reverse counting.
We can give live experiences for subtraction...with the help of concrete objects then introducing place value system in an interesting manner than real life problem solving...
We can teach about substraction by using daily life examples and bu using some activities.
ReplyDeleteThis means the child still didn't learn about substraction. So, we need to give simple example of daily life activities like counting of pencils or toys to substract.
ReplyDeleteIt shows lack of number sense and understanding of the concept.
ReplyDeleteMake the child to understand the word subtraction, and then provide an experience to apply his knowledge on task/ problem
If a child answers 17-9 as12 ,he/she needs to understand the meaning of subtraction as taking away. Teacher should make him/her reach to the conclusion that 9 ones can't be taken away from 7ones therefore the need of borrowing arises.
ReplyDeleteUnderstanding the basic subtraction rule about what is to be subtracted should be repeated by teacher in the class. This shows that the child lacks the concept of subtraction and how to use borrow if the 1 numeral i.e. minuend is less than the subtrahend.
ReplyDeleteWe need to clarify the concept of borrowing to make it clear for the students.
ReplyDeleteThis kind of error shows that the child is not clear about counting concepts. This can be corrected by providing him the hand on material and making them understand the meaning of subtraction and making him count all the objects at once now make him take away the 9 objects and count the remaining left over objects.
ReplyDeleteThis will also help him to come to an understanding of borrowing concept as he learns the 10 s concept.
this show he is not clear about how to subtract. we can use some objects than make him count and subtract
ReplyDeletePlay way method is very easy to understand the problem.
ReplyDeleteBy using tamarind seeds, plastic tokens, coins etc are very useful for the play way method to inculcate mathematics
ReplyDeleteBorrowing is a similar concept, often used in subtraction when working with larger numbers. It involves borrowing a number from a higher place value in order to subtract numbers in a lower place value.
ReplyDeleteThe child has applied their prior knowledge of subtracting a smaller digit from a larger one. However, the child struggles to understand the concept of place value, indicating a need for clarification on this concept first.
ReplyDeleteApply subtraction to real life situations such as taking away toys, beads etc. By using number line also it is easy.
ReplyDeleteStudents should start with building representations of the minuend (the number being taken away from), then taking from the minuend, the value of the subtrahend (the number being subtracted), leaving behind the difference. As students learn this strategy, start with numbers where breaking apart groups is not needed.
ReplyDeleteChild should be clarified the concept of borrowing.
ReplyDeleteThe child must not be aware of counting properly. The child can be taught through context like separating 9 objects from a group of 17 and then count how many are left.
ReplyDeleteA child answers 17-9 as12, means he needs to understand the meaning of subtraction as taking away.The concept of subtraction is to be taught through toy based pedagogy. The false notion of subtracting smaller number from a bigger number is to be cleared. Borrowing concept is to be taught by giving him examples.
ReplyDeleteChild should need to understand the concept of subtraction by giving more learning activities.
ReplyDeleteAs the child is not clear with the concept of subtraction I will use the children as teaching aid and in the story method I will try to make the concept clear
ReplyDeleteIt is confusing to distract bigger number from smaller number
ReplyDeleteMore practice may bring improvement
ReplyDeleteBy this we come to know the concept of subtraction is not clear to the child
ReplyDeleteI will first use concrete objects to teach subtraction. Then I will intoduce borrowing sums. This will be again done with some explanation of Tens and Ones house to make it clear
Make the concept clear to child
ReplyDeleteThe child is doing reverse subtraction and he should be introduced with the concept of carry or borrowing
ReplyDeleteThe child needs to be taught that number with a lower value only needs to be subtracted from the higher value no matter if the digits are smaller except the first digit. And he needs to taught about borrowing concept too in case the digits in the bigger number are smaller
ReplyDeleteIn this one play way based education is important to understand the concept
ReplyDeleteOne of the easy way to teach subtraction is to Involve them in real examples where you give them something and take away a part of it, then ask them to evaluate and derive an answer
ReplyDeleteReal time example using beads and certain other materials will make the child understand the concepts of subtraction.
ReplyDeleteThe idea of easy borrowing should be taught so that he/she doesn't get confused
ReplyDeleteThe child likely confused subtraction with addition. To help, use visual aids like number lines and practice basic subtraction problems.
ReplyDeleteChildren always get confused when it comes to subtract big number from small number.at this stage borrow should be introduced to them.
ReplyDeleteSubtraction should be taught through activities.Children often find it difficult when it comes to do the sums.
ReplyDeleteBorrow should be clarified
ReplyDeleteThe child's answer of 12 suggests they may not fully grasp the concept of subtraction or might be confusing it with addition. To help them understand, use visual aids like number lines or counters. Show how to count backward from 17 by 9 steps. Practice with similar problems and encourage them to verbalize their thought process.
ReplyDeleteWe will use some objects to clarify this problem and resolve the query of the student
ReplyDeleteThe child likely added instead of subtracted, showing confusion between operations. To help, use visual aids like counters or number lines to demonstrate subtraction as "taking away." Reinforce the concept with hands-on activities to build a clearer understanding.
ReplyDeleteI am a teacher from Awadh public school Rajni khand Lucknow.
ReplyDeleteIn our school there are wall painting like shapes with different colours . It actually attracts the students attention on the primary level. They find it very interesting and learn quickly
A child will be asked to count backwards for easy understanding of subtraction

ReplyDeleteThe child misplaced the numbers.May be the child doesn't know the concept of borrowing.
ReplyDeleteEveryday examples are easy ways to teach mathematics.
ReplyDeleteMay be the children did not understand the concept of borrowing.
ReplyDeleteTo clear this concept I'll provide some blocks or candy, firstly I'll ask her count 12 candies and give 9 candies to Friend from 12, then I'll ask to count the rest of the Candies. To make it more clear I'll use some more objects like notebooks, pencil, eraser with different numbers. This will help students to use this concept in real life
ReplyDeleteThere are different methods to Subtract 9 from 17. We should explain each method to the child.
ReplyDelete1. By using finger and keep 9 in our mind and count till 17after 9.
2. By adding 1 to 9 and subtract 10 from 17, later add 1 to the answer.
3. Borrowing method with using BBB rule, i.e. bottom bigger borrow.
The child's answer of 12 for 17 - 9 indicates a misunderstanding of subtraction, possibly due to:
ReplyDeleteMisinterpreting the Operation: The child may have added instead of subtracting.
Place Value Confusion: They might not understand the regrouping or borrowing concept.
Lack of Conceptual Clarity: The child might not grasp subtraction as "taking away" or finding the difference.
How to Help the Child:
Use Concrete Objects: Demonstrate subtraction with counters, sticks, or blocks, physically removing 9 from 17 to visualize the process.
Relate to Real-Life Scenarios: Use story-based problems like "If you have 17 apples and give away 9, how many are left?"
Number Line Practice: Teach subtraction by counting backward on a number line to reinforce the concept.
Simplify Problems: Start with smaller numbers to build confidence before progressing to larger ones.
Peer Learning: Pair the child with a peer who understands subtraction for collaborative practice.
With these strategies, the child can develop a clearer understanding of subtraction and strengthen their math foundation.
I would have started supporting the child with my leads:
ReplyDeleteNarrate a story around the mathematical statement first.
What must we do in this story? - more things to be put or things to be taken away
What does minus say?
How do we take away?
Can we use crayons to tell this story?-Take away 9 crayons from 17, how many are left?
Then I go ahead with Tens and ones concept. Then with the concept of borrowing.
In each level, I would be able to understand the comfort level of my learner. This I can use it as an informal assessment also.
Students first experience subtraction through the use of models. They can use a variety of manipulatives such as cubes, counting bears, buttons, five and ten frames, fingers, or counters. Students can also draw representations or pictures to model the mathematics or even act out the subtraction physically.
ReplyDeleteThe child has the conception that only lesser number can be sustracted from the greater number.tge concept of borrowing from tens or hundreds place is to be .made clear to the children by various activities
ReplyDeleteChildren need to be taught borrowing using concrete objects
ReplyDeleteThe teacher should use real concrete objects from everyday life to teach the concept of subtraction with borrowing.
ReplyDeleteThe child placed 9 as minuend and subtracted 7 from it This he got 12. There a need to make the student that minuend was 17 and sbtrahend was 9. This can be best explained with concrete examples.
ReplyDeleteThe child is not able to distinguish between the two numbers properly. The problems which commonly use addition and subtraction involve an increase or decrease of some quantity, combination of two or more objects and comparison of objects. A common strategy to represent subtraction problems are ‘take away’/ ‘left over’ problems. There are some informal strategies in dealing with addition and subtraction of small numbers as it helps to build a ‘number sense’. These operations are useful to interpret, represent and solve simple problems in daily life context.
ReplyDeleteVery helpful for understanding mathematical concept
ReplyDelete1. Possible calculation error: The child might have added 17 and 9 instead of subtracting, resulting in 26, and then possibly miswritten the answer as 12.
ReplyDelete2. Lack of understanding of subtraction concept: The child might not fully comprehend the concept of subtraction, which involves finding the difference between two numbers. They might be thinking of subtraction as a process of combining numbers instead of finding the difference.
3. Difficulty with number sense: The child might struggle with number sense, which includes understanding the relationships between numbers and their quantities. They might not have a solid grasp of the number line, making it challenging to visualize the subtraction process.
To help the learner better understand the concept of subtraction, I would take the following steps:
1. Use visual aids: I would use visual aids like number lines, counting blocks, or base-ten blocks to help the child visualize the subtraction process. This would enable them to see the difference between 17 and 9 and understand how subtraction works.
2. Real-world examples: I would provide real-world examples of subtraction, such as "If I have 17 pencils and I give 9 to my friend, how many pencils do I have left?" This would help the child connect the concept of subtraction to everyday life.
3. Practice with different numbers: I would practice subtraction with different numbers, starting with simple examples like 5-2 or 10-3, to help the child build their understanding of the concept.
4. Focus on the concept, not just the calculation: I would emphasize the concept of subtraction, explaining that it's about finding the difference between two numbers, rather than just performing a calculation.
5. Encourage self-correction: I would encourage the child to check their work and self-correct their mistakes. This would help them develop a growth mindset and understand that mistakes are an essential part of the learning process.
6. Use technology and games: I would utilize online resources, games, or apps that focus on subtraction to make learning more engaging and fun.
7. One-on-one support: I would provide one-on-one support to the child, working with them to identify areas of difficulty and providing targeted support to address those challenges.
By using a combination of these strategies, I believe the child will develop a deeper understanding of the concept of subtraction and become more confident in their ability to perform subtraction calculations.
Child is struggling with the understanding of subtraction. One possibility is, he/she is taking an extra number into consideration while applying the operation.
ReplyDeleteTeachers explain subtraction to a child in an interactive way: they introduce kids to gains and losses and math operations that reflect them.
ReplyDeleteKids learn to associate numbers with items and realize they can calculate and express losses using math language. Although Common Core math subtraction standards do their best not to overwhelm students with complex subtraction theory all at once, children struggle with this operation anyway.
Yeah, Children struggles while doing subtraction. So, we have to use different strategies to teach them about subtraction like objects, marbles and blocks can be used.
ReplyDeleteFoundational Numeracy refers to the basic mathematical skills that enable young children to understand and work with numbers. It includes number recognition, counting, basic operations (addition, subtraction, multiplication, and division), spatial awareness, measurement, and problem-solving skills.
ReplyDeleteStrong foundational numeracy is essential for higher mathematical learning and everyday life. It develops through engaging activities like counting objects, playing number games, and using real-life examples. Early exposure to numeracy helps children build confidence and logical thinking, forming the basis for future academic success.
As the child got confused to do it in a correct order, we can explain them using the toffees or any other item according to their choice. As these kinds of methods gives us best results. Never explain the methods on board. Basic Math concepts should always be explained through activities.
ReplyDeleteDifferent strategies and examples can be used to clear the concept
ReplyDeleteChildren have a logic in their mind that a small number is subtracted from big number and he consider 7 a separate number and 1 a separate number then we tried to understand them thar 17 is a whole number and here we borrow one from 1 and them proceed further
ReplyDeleteConcept should be made clear to the student by using real life objects surrounding them
ReplyDeleteConcept of subtraction should be made clear using concrete real life objects, can take help of abacus also.
ReplyDeleteThe child's answer (17 - 9 = 12) suggests a misunderstanding of subtraction, possibly confusing it with addition or struggling with place value. To help, I would use hands-on activities like counters, number lines, and real-life examples (e.g., taking away objects from a group). Visual aids, storytelling, and interactive games can reinforce the concept. Encouraging step-by-step reasoning and checking answers through reverse operations (addition) would also support deeper understanding.
