Learning Tips


While driving, during commercial breaks, or at any other free moment, say simple and compound sentences out loud (alternating) and have the child identify the sentence as simple (short, basic) or compound (using conjunctions such as and, or, but, etc.).


Copy a page from a book, article, or magazine. White out or cover up several words all throughout the text. Give the page to your child to have them fill in the blanks. Then compare how close their answers were to the original, particularly whether they simplified sentences, made them compound sentences, or left them the same.


Cut out words from magazines, newspapers, etc. Be sure to include all parts of speech (e.g. nouns, verbs, adverbs, adjectives, etc. – conjunctions especially). Give them to the child to see how many sentences they can make by arranging and rearranging the words. They should make complete simple and compound sentences.


Sentence Stems – In writing and/or in speech (verbally), give the child several sentence stems or prompts and have them complete the sentence. Make some simple and some long enough that the child will have to add to it to make it compound. They can all have the potential, or possibility, of being compound sentences depending on how and what the child adds.

Q: When was the last time you enjoyed a movie?

A: The last time I enjoyed a movie was _____________.

Q: How many times should you brush your teeth every day?

A: It is necessary to brush your teeth twice a day. (could make compound with a “because…”)
