In the Spanish Year 7 lesson, students should find a quiet space for their lessons and set a regular schedule, such as every Tuesday at 10 AM. Essential materials needed include a notebook, a folder, a pencil, a pen, and an eraser. The lesson focuses on vocabulary related to bathroom furniture, such as the shower, bathtub, sink, mirror, toilet, towel, and mat, while also practicing comprehension by matching a description of a bathroom to the correct image. Students will have one minute to complete the exercise based on a provided text description.
