Step 1. Look around the class and ask a few questions to elicit answers as prepositions .
Q1 . Where is your book ?
Ans : The book is on the table .
Q2. Where is your pen ?
Ans : The pen is in the pencil box .
Q3. Where is your friend sitting ?
Pans : She is sitting next to me .
Step 2 . Ask the children about the function of the underlined words .
In sentence no 1 on shows the relation between book and table , in sentence no 2 the word in shows the relation between pen and box and in sentence no 3 the word next shows the relation between she and me .
Preposition is a word that shows in what relation a noun or a pronoun stands with another word in a sentence .
This should follow a few oral and a few written exercises on prepositions .
Step 3.Display a list of various prepositions and arrange them in groups of prepositions of time , position and direction .
Prepositions of time :- in , at , on , by , within , for , since etc .
Preposition of position :- on , under , in ,above , below , between , among ,beside , near , Infront of , behind , next to beyond , inside , outside etc .
Preposition of direction :- to ,from , towards , of , off
Step 4 . Give exercises on each type of preposition through oral questioning , filling the blanks and other exercises .
Make children demonstrate a few situations for using some of these prepositions like behind , Infront , under , on , in , into ,between ,among , by , with etc .
Step 5 . Tell those fine differences between two prepositions similar in meaning like between and among , in and into , by and with , over and above , under and below etc .
