Write one word problem each for comparison model and complementary addition model for subtraction and explain the difference in the two models.
Solve the following number puzzle:
Step 1: Take a number from 1 to 9
Step 2: Multiply the number by 3
Step 3: Subtract 6 from the result obtained in step 2
Step 4: Divide the result obtained in step 3 by 3.
Step 5: Subtract the result obtained in step 4 from the number taken in the step 1. What is the number chosen?
Is the answer same if we take any other number from 1 to 9? Justify.

Explain the differences in the following processes with the help of suitable
examples (apart from the examples given in the material).
i) ‘Concrete to abstract’ and ‘particular to general’.
ii) Inductive and deductive methods of proof.
A child may not be able to perform a task simply because of language incompetence, and not cognitive incompetence. Illustrate the difference between language incompetence and cognitive incompetence while performing a Mathematical task with suitable examples.
“Children learn better in groups “Justify this statement with the help of two suitable examples in the context of learning the concept of “angle”.
When the activity given in Example 4 of Unit 6 of Block 2 was tried with few children it was found that it helped them to add two digit numbers.
Here we want you to try this activity on a sample of minimum 5 children around you and assess whether the activity is effective in helping these children add two digit numbers. Write a report of about 750 words regarding the conduct of the activity which should include the following:
i) Details of children worked with, their academic and social background.
ii) The pre-requisite knowledge required for acquiring the concept and how did you assess whether the children had this knowledge.
iii) Your observations on how the children perform the different parts of the activity
including the quality of peer interaction.
iv) The devices used for assessing/testing the effectiveness of the activity.
v) Analysis of the work done in (iv) above.
vi) The conclusion based on the points above.
