46. A class VII teacher wants to discuss the following problem in the class:

“A square is divided into four congruent rectangles. The perimeter of each rectangle is 40 units. What is the perimeter of given square ?“

Key Mathematical concepts required to solve this problem is

(1) Area of square and rectangle, perimeter of square and rectangle and definition of square and rectangle

(2) Meaning of the terms square, rectangle, congruent, perimeter, etc.

(3) Area of rectangle, perimeter of square

(4) Formation of algebraic equation to solve the problem.

47. Algebra is introduced in the middle classes. According to Piagets’ theory of cognitive development, it is appropriate to introduce algebra at this stage as

(1) the child is at sensorimotor stage and can understand with the help of lots of manipulatives.

(2) the child is at pre-operational stage and can understand abstract concepts.

(3) the child is at concrete-operational stage and he can understand and conceptualize concrete experiences by creating logical structure.

(4) the child is at formal operational stage and is fully mature to grasp:

the abstract concepts.

48. Mr. Sharma was assessing the students’ work on exponents. One of the response sheet was as follows:

(a) 2 power 3* 2 power 5=2 power 8

(b) 3 power 2 * 4 power 2 = 12 power 4

(c) 3 power 3 ÷ 3 power 5 = 3 power -2

(d) 7 power 20 ÷7 power 14 =7 power 6

(e) 9 power 3÷18 power 6= (1/2) power 3

On the basis of this response sheet Mr. Sharma can make the following observations:

(I) Child has understood the laws of exponents and can apply them well.

(2) Child has understood the laws of exponents but has made clerical errors.

(3) Child has understood the laws of exponents but has not practiced the questions involving division of two numbers.

(4) Child has understood the law of exponents for the cases where the base is same and has missed the concept for the case where the base is different.

49. According to Van Hiele level of Geometric thought the five levels of geometric understanding are- visualization, analysis, informal deduction, formal deduction and rigour. Students of class VII are asked to classify the quadrilaterals according to their properties. These students are at —— level of Van Hiele Geometrical thought.

(1) Visualization

(2) Analysis

(3) Informal Deduction

(4) Formal Deduction.

50. A task assigned to the class VIII student is as follows:

An open box is to be made out of a metallic sheet of 50: cm * 65 cm. Length and breadth of the box is 30 cm and 15 cm respectively. What is the possible height of the box ? Also find the volume of this box.

This task refer to

(1) lower level cognitive demand as it requires the knowledge of formulae of volume of cuboid.

(2) lower level of cognitive demand as there is no connection between concepts involved and procedure required.

(3) higher level of cognitive demand as the problem can be solved by making diagrams and connections between many possible situations.

(4) higher level of cognitive demand as it requires the use of conceptual understanding that underline the procedure to complete the task.

51. Mr. Nadeem gave the following task to his class, after completing the topic on lines and angles:

Speak for 2 minutes on the following figures using your knowledge about lines and angles:

This task is

(1) Reflective in nature, can be used to pass time.

(2) Exploratory in nature, can be used for summative assessments.

(3) Reflective as well can be used for formative assessment.

(4) Communicating and can encourage Mathematical Talk in the classroom during free time.

52. A child of class VII defined the rectangle as follows:

“Rectangle is a quadrilateral whose opposite sides are parallel and equal.”

The definition reflects that the child

(1) cannot recognize the shape.

(2) do not know the correct properties of the shape.

(3) knows the properties of the shape, but repeated some properties in definition.

(4) knows some properties, but missed some important to complete the definition;

53. A very common error observed in addition of linear expression is 5y+3=8y.

This type of error is termed as

(1) Clerical error

(2) Conceptual error

(3) Procedural error

(4) Careless error

54. Read the following question from the class VI text-book:

“Prabal deposited Rs 5,000 in a bank at the rate of 5% interest per - annum. After 2 years he withdrew the money to purchase the study table for Rs 3,500. He deposited the money left with him again at the rate of 5% interest per annum for another two years. How much amount will he receive after two years ?“

What values can be inculcated in students through this question?

(1) Honesty

(2) Habit of saving money spending it wisely

(3) Sincerity

(4) Simplicity and helping others

55. Following is a problem from text-book of class VI:

“Express the following statement through linear expression:

Neha has 7 more toffees than Megha. If Megha has x toffees, how many toffees does Neha have ?“

Which competence of Bloom’s cognitive domain is referred. in the above question?

(1) Knowledge (2) Comprehension (3) Analysis (4) Synthesis

56. If p = 3 power 2000 + 3 power -2000 and q = 3 power 2000 – 3 power -2000, then the value of p2 — q2 is(1) 1 (2) 2 (3) 3 (4) 4

57. The square of 9 is divided by the cube root of 125. The remainder is

(1) 1 (2) 2 (3) 3 (4) 4

58. The value of square root 16 square root of 8 square root of 4 .is
