ReplyDeleteLearner is having place value misconceptions.
Firstly, the concept of substraction in child's mind is roughly clear but the results are Incorrect.
ReplyDeleteSo to make them easily understand, I will explain it by using locally available teaching aids. By taking stonechips as an example.
Display them:
Out of 17 stonechips
9 stonechips are dropped out.
8 stonechips remains. This way they can better understand the concept of substraction.

We knew that the child's is not familiar with the actual concept of doing subtraction but he had having a little idea or knowledge about solving this problem.For better understanding the concept of subtraction,we should act as a facilitator not an information provider to the learners.We should teach them to place or arrange the numbers in proper place.Thereafter we'll tell them to find out the difference by using sundry of play materials which is available in and around the classroom.For example,order the child to bring 20 sticks and out of it tell him to give 8 sticks to his friend.Let the child be given an opportunity to count the left sticks with him.In this way,the child will learn the correct method of finding subtraction.
ReplyDeleteConcept of substraction and counting is not clear to the child. To begin with the child should be thoroughly familiarised with counting numbers sequentially. He/she should have a clear understanding of 'greater than' and 'less than'. After that the concept of substraction is to be introduced to him/her in a way that he/she understands, preferably by using local aids.
ReplyDeleteThis shows that the child didn't understood the concept of subtraction well.Thechild need more support from the teacher to understand the concept of subtraction.This also indicates that the child need more attention on this topic. To help the child,teacher should make learning concept easier for them to understand, first of all teacher should clear the doubts of the child about the place value table and then help them to make clear concept of subtraction.Teaching of subtraction can be done in a Play full manner where the child is comfortable to perform these activity, for example,we can use educational props to make learning easy for the child.

There are many ways to make him the child understand about subtraction in simple way the child ask to drag seventeen line after that serially cut the nine line the remaining un cut line will be the answer...
ReplyDeleteTo understand the concept of subtraction in foundational stage children are needed to clear understanding and meaning of subtraction, By using locally available TLM aids like small stick,small stone or marbles to display them to understand the concept well, at first let them to count 17 marbles and out of 17 marbles and let them to dropped out 9 marbles, and then let's students to count remaining marbles, In this way pick up the concept of subtraction,
ReplyDeleteThe concept of substraction in child's mind is not clear fully and the results are Incorrect.
ReplyDeleteSo to make them easily understand, explaination should be made using locally available teaching aids. Example by taking stone concept of subtraction which taking away can be explained.
Like:
Out of 17 stones if
9 stones are taken away.
8 stones remains. This way they can better understand the concept of substraction.
The child has carried over 1 as is, and subtracted 7 from 9 to get 2. He/she probably thinks this is how the subtraction is to be done since 9 is greater than 7. This shows that his/her knowlege of subtraction as well as that of the number system is incorrect.
ReplyDeleteTo correct this, I will explain these concepts to the student using real-life examples, followed by assessing their learning using more questions.
Children begin learning mathematics well before they enter elementary school. Starting from infancy and continuing throughout the preschool period, they develop a base of skills, concepts, and misconceptions about numbers and mathematics. The state of children’s mathematical development as they begin school both determines what they must learn to achieve mathematical proficiency and points toward how that proficiency can be acquired.
