A, An & Where Is It? — Grammar Worksheet

About This Resource

A three-part grammar worksheet that teaches the a/an article rule, practices the prepositions on and in, and has students unscramble sentences built from the unit's two target question-and-answer patterns.

Overview

This worksheet gives focused, written grammar practice to complement the oral work in Resource 4. Part A has students choose a or an for six pictured classroom objects, using "eraser" as the one example that takes an. Part B has students choose on or in to complete five location sentences. Part C has students reorder scrambled words into the four target sentences: "What is this?", "It is a book.", "Where is the pencil?", and "It is on the desk." A complete, verified answer key is included.

Grade 1 35-45 Minutes Grammar

Student Task

Teach or review the a/an rule using Part A's instruction line before students begin.
Have students complete Part A and Part B independently.
Model one example of unscrambling a sentence before students attempt Part C on their own.
Check work together or using the included answer key.

Classroom Use

Write each Part C sentence's scrambled words on separate strips of paper or the board, and have small groups physically arrange (or come up and rearrange) the strips into the correct sentence order as a race.

Differentiation

Support: complete Part A together as a class before releasing students to Part B and Part C independently, and allow students to reference their Resource 1 flashcards. Extension: have students write one original sentence of their own using on or in about a real object in the classroom.

Learning Objectives

Students will be able to choose the correct preposition (on or in) to describe an object's location.
Students will be able to reorder scrambled words into a correct question or statement using the unit's target grammar patterns.
