Prepositions vs. Conjunctions
Students will be able to determine whether to use a conjunction or preposition in a text and explain their reasoning.

Explicit Instruction/Teacher modeling(5 minutes)
- List the following prepositions and conjunctions on the board: under, through, and, or.
- Read the student objective and define conjunction as a word used to connect two clauses (e.g. and, but, nor, or, for), and write the definition on the board.
- Define a preposition as a word that shows where something is or when something happened, and write the definition on the board.
- Write the following on the board: The teacher walked ____ the classroom.
- Read through the sentence, and fill in the blank with the correct preposition from the options listed on the board.
- Think aloud about your choice by placing some of the words on the line and reading the sentence. Eliminate the conjunctions because there are no clauses in between the blank. Reinforce the decision to use a preposition in this sentence by showing that the sentence mentions a location (i.e. the classroom).
- Read through the correct sentence: The teacher walked through the classroom.
- Explain that you chose this preposition based on the options given.
