Let them write sentences with them for a few minutes. Kids could read their sentences out and aloud while someone copies them on the blackboard. Check meaning and spelling. In general, students are not particularly fond of dictations. However, you may wish to give them one now and again to improve their spelling, their vocabulary range or their listening abilities.
Dictations are useful.
Your text should not be too long, as dictations require concentration and can be a bit stressing. It often helps if you care to read the whole text again at normal speed when the dictation has been completed, as this gives students a chance to check their work before you mark it. Emphasize that they should be honest. In this way, your students will no doubt overcome their fears and, with practice, they will improve their talents, which is what we all want. Write it on the blackboard for everybody to see.
