Grow Your Ideas: Expanding to Complex Sentences for Class 2

This Class 2 worksheet helps children expand short, simple sentences into richer, more detailed complex sentences using joining words such as “because,” “when,” and “who.” Students learn how adding a reason, time, or describing clause can make their writing clearer, more expressive, and more meaningful.

Through underline-and-identify tasks, multiple-choice questions, sentence expansion, a passage with blanks, and a short writing task, the worksheet guides children step-by-step to build longer sentences without losing clarity. These activities support early creative writing, grammar development, and expressive language skills.
