Dear Students!!! There is most general as well as a scoring section in all the competitive entrance examinations in the teaching field i.e “Mathematics”.Because in this section only one thing is work i.e your accuracy and that could be nourished with the daily practice. So, for this, we are providing you the daily quiz for all teaching exams i.e CTET Exam 2018, DSSSB ,KVS,STET Exam.

**Q1. A mathematics teacher made a statement in the class – ‘Sum of the three internal angles of a triangle is always equal to 180°. She asked the students to draw one triangle each (any shape or size) in their notebooks and measure their angles to find if their sum is actually equal to 180° or not.

(d) give training to the students in life skills

**Q7. A Class III student multiplied 35 by 5. The answer given was**

**What type of error is it ?**

(a) Wrong algorithm

(b) Regrouping error

(c) Basic fact error

(d) Incorrect operation

**Q8. Formative Assessment in mathematics at primary stage includes**

(a) identification of common errors

(b) testing of procedural knowledge and analytical abilities

(c) grading and ranking of students

(d) identification of learning gaps and deficiencies in teaching

**Q9. A teacher plans the following activities to introduce the concept of ‘half’ to Class III students :**

**A. Shows pictures representing ‘half’**

**B. Writes symbol of ‘half’**

**C. Divides many types of concrete materials into ‘halves’**

**D. Uses story or words to represent ‘half’**

**Which one of the following is the correct sequence of the activities of the activities that the teacher needs to follow ?**

(a) C, A, D, B

(b) C, D, A, B

(c) A, B, C, D

(d) B, A, C, D

**Q10. “Errors play an important role in mathematics,” This statement is**

(a) False, as there is no scope of errors in mathematics

(b) False, as errors indicate carelessness

(c) true, as they give ideas about how children construct mathematics concepts

(d) true, as they give feedback to students about marks

**Answers**

S1. Ans.(b)

Sol. The students have actually verified the statement given by the teacher, i.e. they moved from a generalized statement to specific cases exhibiting that property. Deductive reasoning is when you move from things you know or assume to be true – called ‘premises’ – to conclusions that must follow from them.

S2. Ans.(b)

Sol. At the primary level, to effectively teach the concepts of half past, quarter past/quarter to, a.m./p.m., relation between minutes and seconds, difference between noon and midnight, etc, a teacher can make use of teaching-teacher materials such as digital and analogue clocks. The students can then be made to read time on both types of clocks, which will help them to tell, estimate and convert time with increasing accuracy.

S3. Ans.(b)

Sol. The grid represents the place value as 3 ones and 3 tens. The students may be involved in the activity of showing different numbers on a square paper to reinforce the concept of place value.

S4. Ans.(a)

Sol. The error is related to conceptual understanding. She has ‘the longer the larger, thinking about decimals. For her, 3.05 is greater than 3.4 as it has more number of digits and 3.251 is the largest as it has maximum number of digits.

S5. Ans.(a)

Sol. It is a regrouping error. The students has been able to add the numbers but could not regroup 13 ones as 1 ten + 3 ones. The student lacks the understanding of place value.

S6. Ans.(b)

Sol. She is doing formative assessment by training the students to work in groups and develop life skills

S7. Ans.(c)

Sol. It is a basic fact error the student does not have a good knowledge of tables.

S8. Ans.(d)

Sol. Formative assessment is diagnostic in nature. Its purpose is to find students learning gaps and deficiencies in teaching and provide a timely remediation. Although it also helps identify the errors (which include common errors as well) committed by each student so as to provide remedial teaching well in time, it has nothing to do with testing of procedural knowledge and analytical abilities or grading and ranking of students.

S9. Ans.(b)

Sol. The teacher should first divide many types of concrete materials into halves, then use a story or words to represent half, next show pictures representing half and lastly write the symbol of half.

S10. Ans.(c)

Sol. A maths teacher can understand from the errors of his/her students that whether they have gained a good grasp of a certain concept. The teacher should also inculcate the habit of error analysis in the students so that they know what went wrong in their solution and be able to successfully solve other problems based on the concept.
