Illustrate you explanation in the context of learning the concept of “size”.
Suppose you want to teach a unit on “data handling”. What are different lessons you would divide this unit into. For any one of these lessons create a lesson plan.
Estimation is a difficult skill to master. Explain why it is difficulty in the context of measuring height. Suggest an activity to assess that a group of children have mastered the skill for estimation. Explain why this activity is an “assessment activity.
“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.
