This Grade 2 medium-1 sheet introduces multiple signal words: because, so, and since. Nine fill-in items ask students to choose the right signal to connect a cause and effect, or to complete the missing half of the sentence. A matching activity pairs four causes with four effects across mixed topics like weather, plants, school, and pets. Students must read both sides carefully before drawing lines.
