You could ask the students what they think the question might be for the situation in the picture. If someone suggests the answer or something very close to it, reveal the question for the picture. If there are no suggestions you could give some hints. I reminded the students to look at the hint phrases on page 64 of the textbook. Students repeat each question after you. If they need more practice before starting the worksheet, you could run through the slides one more time.
