This Grade 3 English grammar worksheet focuses on understanding root words and word families to help learners see how words are connected. Students explore how a single root word can form many related words by adding suffixes or changing word forms.
The worksheet builds vocabulary skills by showing how root words help learners guess meanings of new words. Through matching activities, children identify nouns, adjectives, and descriptive words that belong to the same word family.
Designed for Class 3 learners, the exercises are simple, visual, and engaging. Matching tasks encourage logical thinking while strengthening spelling, meaning, and word usage in everyday language.
By practicing root words and word families, students develop stronger reading comprehension, improved vocabulary, and confidence in forming and understanding new words.
