2. Class room interaction procedure Pupil response
Today we are goingto introduce a new methodforlearninganew idea.
Are you ready?
Can yousay some objectsfromyourclass room
What are theirspecialty
Is anyother specialty
Yes youare right.
I have a small ideainmy mind.Youhave to findoutmy idea.Forthat I will
showyousome right example andwrongexample.
NowI am goingto showtwofigures.Observe boththe figure clearly:
What isthis?
What istheirspeciality?
Is onlyone specialty.
Try to say more features
Yes I have sowedyoutwoanimalshavingdifferentshape ,size, color.This
was a wrongexample.

3. NowI am goingto showanothersetof figures.
What isthis?
What can you sayabout these temples
Yes verygood
I have showedyouobjects havingsame size,same shape.Thiswasa right
example.
AgainI am goingto showa rightexample.
What can you sayabout these figures
Model of twotemple
Theyare of same size,same shape
Both are rocketshaving same shape
4. What abouttheirsize
Both the objectsare of differentsize andhave same shape.
Can yousay whatwas my idea:
Yes youare partiallycorrect,saysome more correctly.
Mathematicallyobjectshavingsame shape anddifferentsizehave acommon
name.Can yousay?
Geometricshapeshavingsame shape anddifferentsizesare calledsimilar
figures.Thisobjective canbe termedassimilarity.
Nowcan you define whatissimilarity.
NowI am goingto give some more examples.Identify similaranddis-similar
one.
Theyare of differentsize
Objectshavingsame shape.
Objectshavingsame shape and
