Course 9 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.
Break it up. Don't overwhelm your child with all of the subtraction facts at once
ReplyDeleteConcept of regrouping is not known by the child
DeleteLOGICAL REASONING MISSING
ReplyDeleteBy making them understand the basics of subtraction. Using real objects, by using the number line, by making them understand how to subtract the bigger number, by telling the story, also with simple understanding languages.
ReplyDeleteBasic mathematical operations can be taught to the students by using objects or toys using play way methods.
ReplyDeleteExplaining the concept of smaller and larger number over and over again.
ReplyDeleteBy explaining the difference between bigger number and smaller number in his/her language if possible and then with the help of bundle and pencils practically showing the subtraction.
ReplyDeleteexplaining the basics of subtraction and concept of big number
ReplyDeleteChild can be taught by initially using the process of correspondence and then seriation to achieve the goals of teaching her the process of counting. One must start off by using small number preferably single digit numbers.
ReplyDeleteBy picking 9 beads from 17 and counting how many left gives him correct answer
ReplyDeleteIt shows child basic concept is not clear. We will teach him through demonstration method like with matchsticks.
ReplyDeleteWe need to teach students concept of carry over starting with finger counting or with the help of beads or cubes.
ReplyDeleteThe child needs to have better understanding of the fact that 'by how many? is a smaller number more than the bigger number.
ReplyDeleteAs a first step, this concept must be made clear using seeds/ pebbles in a linear manner with one to one correspondence- one below the other.
The answer can be approached later by take away method - removing the objects from the end having the more number of objects of a given number.
Teacher needs to once again use mathematical communication to redevelop the concepts of mathematical operations.
ReplyDeleteBy making the numbers on top (or at least some of them) bigger, you can make the subtraction easier.
ReplyDeleteNot only will this help students increase their number sense and mental math skills, but it will help them to better understand subtraction, as well as build a foundation for later algebra learning.
Thanks
Step wise process for a child should be followed.... subtraction should be started with 1-digit number. It will clear the concept of bigger and smaller. Through playway methods he can grasp the concept easily. No doubt correspondence and seriation will play the vital roles.

ReplyDeleteउत्तर को बाद में टेक अवे विधि द्वारा प्राप्त किया जा सकता है - किसी दिए गए नंबर की वस्तुओं की अधिक संख्या वाले वस्तुओं को अंत से हटा देना।
As the child is in pre-primaty so l will explain him\her with the help of beads i.e. take out 9 beads out of 17. After that I will make them understand by borrowing method.
ReplyDeleteI will explain the concept of substraction by using marbles and ask the child to take out 9 marbles out of 17 marbles.then the child will count the marbles that remain.the child will also learn the concept of lesser and greater than.
ReplyDeleteexplaining the basics of subtraction and concept of big number
DeleteConcept of subtraction will be explained
ReplyDeleteFirst of all take 17 pebbles then take out 9 pebbles show the child how many has left(concrete knowledge)
ReplyDeleteNow make them understand by taking borrow. In both way we r reaching the same number. So always choose the easy one. When there would we large number we will not use the first one.
First of all we will explain to the child the difference between a small number and a large number. Then we will raise two children in the classroom and ask for 15 children's pencils from the classroom and tell one child that 8 out of them. The pencils will be returned. Then we will recalculate the remaining pencil with the child. By doing this the child will also understand the rule of subtraction that always the smallest number is subtracted from the larger number and also got the correct answer.
ReplyDeleteFirst of all all the basic of subtraction will be made clear and very simply methodology to subtract numbers will be used. like real objects will be provided or shown to children to understand the subtraction facts easily. The things in their hands can be used like pencils, erasers, chalk pieces and then make them understand how to subtract them easily
ReplyDeletethe concept of subtraction has to explained again. more practice needs to be given
ReplyDeleteTeachers needs to go through with more examples.
ReplyDeleteDoing practical activities and giving real life situation examples can make the child understand
ReplyDeletePractical activities will help in this situation.Teacher needs to once again use mathematical communication to redevelop the concepts of mathematical operations.
ReplyDeleteThis shows that child is quick in counting /subtracting specifically. His concepts are clear. He knows the concept of numbers, greater than Or less than very well.
ReplyDeleteThe teacher can also ask this question by taking some concrete examples, some objects.
I shall reinforce the basics
DeleteI will show him the process by the help of taking out 9 stones from 17 Stones and will tell him to count the remaining
ReplyDeleteI will explain the difference between bigger number and smaller number in his or her language and then with the help of objects, practically show the subtraction.
ReplyDeleteActually I will help the child by giving real situation.I will give things like pencils or 17 toffees will be used then will be asked to take away 9 toffees and will be asked to count the remaining toffee orpencils
ReplyDeleteSubtraction can be taught to children through various activities. Kids learn better when taught in playway method. Activities like - Subtraction as take away using different objects, draw and deduct method, etc
ReplyDeleteTeacher needs to teach the subtraction by using toys or marbles.. Toffies etc. The concept of subtraction can be explained through day to day life example..

ReplyDeleteBy explaining the concept of bigger and smaller with the help of real objects present in the classroom. then with the same objects will tell him a story and show how to subtract / remove the smaller no from the group and , counting the remaining ones to know how many are left behind. the child will himself understand where he made the mistake and learn to subtract correctly. some more practice can be given ....with other kids and objects in the class .
ReplyDeleteBy explaining the concept of bigger and smaller numbers with help of real objects initially and then introducing the concept of the difference between the two numbers by counting on finger lines.
ReplyDeleteSuch child needs more concept clarity that can be done by activity or practical method.
ReplyDeleteThe teacher should teach the child about basic concepts of Subtraction by giving live examples and with the help of different activities.
ReplyDeleteBasic concepts of Mathematics will be taught by giving him/ her 17 toffee or objects then will be asked to give 9 objects to his friend and will be asked to count the remaining objects.In overall hands on experience will be given to explain the concept.
ReplyDeleteThe child has to be taught concept of subtraction by play way method.
ReplyDeleteexperiential learning ,reflection and repetition of the same type of questions with different numbers would help
ReplyDeleteChild reading and concentration missing, he is looked it as 19-7 and given answer 12 which is right from his point of view. Now we have to make then learn to read the question properly and corrrectly befor answering the question : like put finger on letter, repeate the question, read the question loudly etc.. we can correct him/her.
ReplyDeleteThe child should be explained subtraction through objects and experience in his daily touch and observation.
ReplyDeleteBut before that it should be assured that the concept of numbers numbername is clear to the child.
Subtraction can be introduced as taking away and left over etc.
defect in the concept of counting
ReplyDeleteThis means the child has not understood the concept of subtraction using two digits that is tens and ones place. We can make him understand it by using real objects . Also grouping tens and ones using objects and showing how to subtract these real objects.
ReplyDeleteI feel here the child has mixed up the numbers, she/he has read it as 19-7 instead of 17-9. The child knows what subtraction is and how to solve. Will ask the child to read the numbers carefully , if the answer is still not right then will teach her/him the concept once again.
ReplyDeleteThis means child has not understood the basic concept of subtraction. First we can teach single digit subtraction using real objects such as blocks, beads etc and make him understand the concept then move on to the double digit subtraction( without carry forward) after that will teach them this types of sums.
ReplyDeleteThe child should feel more comfortable with numbers and that we can start from the beginning stage of learning mathematics with more games.
ReplyDeleteExplaining the smaller and larger objects again and again
ReplyDeleteThe child needs to have better understanding of the fact that 'by how many? is a smaller number more than the bigger number.

Pupil can be given 17 blocks to make him understand the fact that 'by how many? 17 -9
ReplyDeleteThe answer can be approached later by take away method one by one he will take out 9 and will be made to find correct answer.
First to teach him about the mathematical language about tking away , use method of story, loclly available material to build the same concept and start with one digit subtraction .
ReplyDeleteChild is lacking with concept
ReplyDeleteThe child should be taught pre number concepts of biggger than and smaller than before introducing the concept of subtraction and it should be made clear that from big number the take away of smaller number can be done.
ReplyDeleteFirst of all child's thinking develops age wise .there is no one reason for making such mistake.The child does not know to compare the numbers or strategies of subtraction.
ReplyDeleteBasic numeracy knowledge must be taught to children instead of wrote learning
ReplyDeleteA child can be given 17 candies. He would give away 9 to his classmates and then asked how many are left. This looks practical and every time we cannot give him candies to do subtraction. Carry over concept can be revisited and revised. It is more and more practice and it helps.
ReplyDeleteConcept of regrouping in subtraction is not known,so initially concept of subtraction will be given by using objects.
ReplyDeleteBasic mathematical operations can be taught to the students by using objects or toys using play way methods
ReplyDeleteChild is lacking in basic mathematics concepts , can explain simple subtraction using objects.
ReplyDeleteBasic concepts to be clear.
ReplyDeleteBasic mathematical skills like counting, matching ,shapes,patterns etc.need to be explained in a simpler way using coins,buttons,leaves etc.Instead of rote learning,with several practice work,the concepts of addition, subtraction, division and multiplication etc may be mastered by the children.
ReplyDeleteCan clear basic concepts using more simple examples
ReplyDeleteUse beads to help them group and find out.
ReplyDeleteFirst the child should be taught the concept of big and small numbers. The concept can be made clear using concrete objects like pebbles, counters etc
ReplyDeleteFirst off all explain to differentiate between large and small numbers by a simple activity using stone pebbles or any thing that will help them learn by observing.
