** A child of Class III reads 482 as four hundred eighty two but writes it as 40082. What does this indicate for a teacher?**

(1) Child is not attentive in the class and is a careless listener

(2) Child is a careful listener but has not established sense of place value

(3) Child is confusing the expression of number in expanded form and in short form

(4) Teacher should teach the concept of place value when the children are able to write numbers correctly

** To introduce subtraction of two-digit numbers in Class• 111, a teacher proceeded in the following steps:**

Step I: Revision of two-digit numbers with understanding of place value system..

Step II: Use of tally marks to show that smaller number can be subtracted from larger number.

Step III Application of subtraction on numbers under each column of place value.

In this case teacher is developing the lesson

(1) from system concept —* operation algorithm

(2) from operation —+ system concept algorithm

(3) from algorithm — system concept operation

(4) from system concept —* algorithm operation

** “Which two numbers when multiplied give the product 24 ?“ This question**

(1) is an open ended question as it has more than one answer

(2) is a closed-ended question as it has) definite number of answers

(3) suggests general problem-solving strategy to the child so that he/she can answer correctly

(4) helps the child to think metacognitively

** The students of Class V were able to attempt the problem 1/2 ÷ 1/3 correctly, but not able to solve the problem ‘How many 1/3 cake pieces** **are there in half a cake ?“. The reason is**

(1) students’ language development is poor

(2) problem is of higher difficulty level for Class V

(3) operations on fractions are taught without contextualization and language support

(4) students are not able to understand the mathematical equivalence of the two problems

** Hamida always allow her students to observe the number pattern and to form conjectures on their own in order to enhance their mathemical abilities. She wrote the followin problems on board and asked the students to write the answers:**

**21÷7= **

** 2.1÷0.7= **

** 0.21 ÷ 0.07 = **

** 0.021 ÷ 0.007 =**

Through the set of questions she wants the students to observe that

(1) as one factor is divided by 10 and the other is multiplied by 10, the product remains same

(2) as one divisor is decreased by 10 and the other is increased by power of 10, the product remains same

(3) if both the divisor and the dividend are increased or decreased by power of 10, the quotient remains the same

(4) if both the divisor and the dividend are decreased by power of 10, the quotient is also decreased by the power of 10

** Piaget believed that learning results from social instruction and a mathematics teacher believing in Piaget’s theory shall use**

(1) lots of manipulatives and lab activities in the class

** Pradeep was shown a broken ruler**

and asked, where is 5 cm on the ruler. He picked up the ruler and pointed at the mark of 5 cm on the ruler. His answer

(1) is correct as he rightly pointed out the mark of 5 cm on the ruler

(2) is incorrect as he is showing a point only and not the distance between two points marked as 0 and 5

(3) is incorrect as the ruler is broken and he must start with 2 and should point at 7 as the desired mark

(4) is reflecting that he has the misconception that 5 cm refers to a point and not to a length

** Uma was not able to understand the concept of odd and even numbers. In order to improve her understanding, the teacher took some 20 pebbles of different colours and asked her to pair them up and sort out the numbers from 1 to 20 for which pebbles get paired up or do not get paired up. Uma**

(1) is a visual learner

(2) is a kinesthetic learner

(3) is an auditory learner

(4) needs personal attention

** Rubrics of assessment for the geometry lesson on points and lines in Class IV shall be**

(1) can differentiate between line and line segment, can mark a point, can draw a line segment of given length accurately

(2) can measure the line in cms and inches accurate’y, can name the line

(3) can measure the line segment in cms and inches accurately and can mark end points of line segment

(4) can differentiate between line, ray and line segment and can define them

** In a class, a teacher asked the students to define a quadrilateral in different ways — using sides, using angles, using diagonals etc. ****The teacher’s objective is to**

(1) help the students to explore various definitions

(2) help the students to understand quadrilateral from different perspectives

(3) help the students to memorize all definitions by heart

(4) help the students to solve all problems of quadrilateral based on definitions

** Students arc asked to establish a relation between vertically opposite angles. They draw ‘various figures, measure the angles and observe that vertically opposite angles are equal. In this case, students according to Van Hide**

thought are at

(1) Quiz

(2) Role play

(3) Crossword

(4) Survey-based Project

** Classroom discussion was initiated in Class V on ‘Sale’ in festival season, during topic of ‘Percentage’. This type of discussion in classroom**

(1) helps the students to listen to each other’s opinion and encourages them to present their argument
