Joining sentences: and, but, because, so — English writing skills for kids

Writing tip

Ask how the ideas are linked — “adding → and, different → but, reason → because, result → so”

1. and → adds a similar idea (I brushed my teeth and I washed my face).
2. but → the ideas are different or surprising (The box was small but it was very heavy).
3. because → the second part is the REASON; so → the second part is the RESULT (It was very hot, so we went for a swim).

Use it for: Writing longer, smoother sentences in stories and answers, and “join the sentences” exercises.

Worked example: Fill the gap with the best joining word: → because
