Word Power Builder: Suffixes (-tion) Forming Nouns for Grade 4 

This Grade 4 worksheet focuses on Suffixes (-tion forming nouns) and helps students understand how verbs change into nouns by adding the suffix “-tion.” It is specially designed to strengthen word formation skills, vocabulary development, and sentence construction in a simple, age-appropriate way.

In this worksheet, learners explore how action words like celebrate, protect, invite, and educate transform into nouns such as celebration, protection, invitation, and education. Through engaging grammar-based exercises, students build clarity about how words function differently in sentences.

Why Suffixes (-tion) Matter in Grammar? 

Understanding suffixes is an important step in mastering English grammar. For Grade 4 learners, this topic is essential because: 
1. It teaches how verbs can be changed into nouns using “-tion.” 
2. It expands vocabulary and improves word recognition skills. 
3. It strengthens reading comprehension by identifying word families. 
4. It improves writing skills by helping students use abstract nouns correctly. 

What’s Inside This Worksheet? 

This worksheet includes five structured activities that help learners confidently form and use -tion nouns:

Exercise 1 – True or False 
Students read sentences about word origins (e.g., “Celebration comes from celebrate”) and identify whether they are correct. If incorrect, they mentally recognize the correct base word form. This builds word awareness and spelling accuracy.

Exercise 2 – Sort the Words 
Students sort given words into Correct -tion Words and Incorrect -tion Words. This sharpens spelling skills and helps learners identify common suffix mistakes like “organizetion” or “realizetion.”

Exercise 3 – Fill in the Blanks 
Students choose the correct noun form (invent/invention, donate/donation, etc.) to complete meaningful sentences. This helps them understand context-based usage of abstract nouns.

Exercise 4 – Multiple Choice Questions 
Students select the correct -tion noun to complete sentences. This reinforces grammar rules and ensures they can distinguish between verbs, nouns, and related word forms.

Exercise 5 – Sentence Writing 
Students write their own sentences using words like action, examination, prediction, protection, and completion. This encourages creative expression while applying grammar knowledge correctly.

This worksheet builds strong foundations in word formation and prepares students for advanced vocabulary and structured writing tasks.
