Reading sentences is the first step to your child’s future of composing grammatically correct and meaningful sentences. Most sentences have a cause and an effect. That is, one part of the sentence tells readers the cause of an event, and the other part tells readers the effect of the cause. In this worksheet, there are four incomplete sentences. At the bottom of the page are four options, which are appropriate completions for the sentences at the top. Help your kids check the letter of the effect for each cause.
