- Fix it. Make each sentence grow: add the words in parentheses. Write the new sentence on the line. 6 sentences to fix per page.
Every version prints on US Letter or A4, with its answer key on the last page.
How to teach this
Read the kernel aloud, then the growth word, then ask where it sounds best. Almost always the answer is at the end, and hearing it beats explaining it. Celebrate the before and after: two words became five, and the sentence got a picture in it.
Watch for: Kids copy the kernel and forget the new words. Have them touch each parenthesis and check it made it into the sentence before moving on. Kids drop the period when the sentence grows. The end mark moves to the END of the new sentence; nothing gets to trail after it.
Common questions about expanding sentences
- What does my child actually write?
- The whole new sentence on the line under the kernel, capital to period. The answer key shows the model sentence, so checking is a glance.
- Why start from a kernel instead of writing from scratch?
- A kernel removes the blank-page problem. Your child spends the effort on the growing part, which is exactly the skill first grade writing needs next.
