What Your Child Will Learn
- Identify the two main parts of a simple sentence: a naming word (subject) and an action word (verb)
- Combine a subject and predicate to create simple, grammatically correct sentences with 3-5 words
- Recognize that simple sentences tell who or what is doing something and what they are doing
- Apply capitalization and ending punctuation (periods) correctly when writing simple sentences
How to Use This Worksheet
- Step 1: Read the first problem aloud together as a pair. Point out the subject (who or what) and the action word (what they're doing). Say the complete sentence aloud as a model before your child writes or marks their answer.
- Step 2: Have your child identify the subject by asking 'Who or what is this about?' and circle or underline it. This isolates the naming word and helps them focus on one part at a time.
- Step 3: Ask your child to find the action word by asking 'What are they doing?' This reinforces that every sentence needs something happening, not just naming something.
- Step 4: Guide your child to read the complete sentence aloud and check that it sounds right and makes sense. If it doesn't, work together to fix the subject or action word.
- Step 5: After completing all 10 problems, celebrate each correct sentence by having your child read it aloud with confidence. This builds fluency and shows that sentence-building is about communicating clear ideas.
Tips for Parents & Teachers
Start each sentence with a concrete example using familiar classroom objects or characters (e.g., 'The cat sits'). Many G1 students struggle to understand sentence parts abstractly, so visual or physical demonstrations help them see that every sentence needs 'someone or something' and 'what they do.' Point to the subject first, then the action, so they understand the sequence.
Watch for the common mistake of students writing sentence fragments (missing either the subject or verb). When you see 'Run fast' instead of 'The dog runs fast,' gently guide them to ask: 'Who or what is doing this?' and 'What are they doing?' This becomes their checklist for every sentence.
Use consistent, repetitive language when teaching sentence parts. Always say 'naming word' for subject and 'action word' for verb at this level—avoid advanced grammar terms. This consistency helps G1 students build a mental framework they can apply to all 10 problems on the worksheet.
Frequently Asked Questions
Why is it important for first graders to practice simple sentence building?
Simple sentence building teaches G1 students the fundamental structure of all writing. By mastering the subject-verb pattern, children develop a foundation for speaking clearly, writing stories, and eventually reading more complex texts. It also builds confidence because they can create their own meaningful sentences from the start.
What should I do if my child writes a sentence without an action word, like 'The cat' instead of 'The cat sits'?
This is very common at the G1 level. Gently ask, 'What is the cat doing?' If they say 'sitting,' write 'The cat sits' and point out that now we know both WHO it is AND WHAT they're doing. Use this as a teaching moment, not a correction. After a few examples, they'll naturally include the action word.
How can I help my child remember to use capital letters and periods in their sentences?
Make it a two-part check: First, ask 'Does your sentence start with a big letter?' Then ask, 'Does it end with a dot?' Some children respond better to a physical checklist they can mark off. You can also create a simple anchor chart showing a correct sentence with arrows pointing to the capital letter and period.
Should I correct every mistake my child makes on this worksheet?
Not immediately. Allow your child to complete a few problems independently first, so you can see what they understand. Then gently guide them through one or two corrections together, using the 'Who? What are they doing?' questions. This balanced approach builds independence while preventing frustration.
