Students can't access assigned skills
Hi. I assigned a skill for my students this week (from level 3 in Spanish) and I have students who say they can't access it without unlocking level 3. I had always thought (from doing this for years as homework for my classes) that if I assign a skill, even if it was in a locked level, students could still access the skill. Any ideas as to what I can say to my students to help them short of "do all the skills ahead of it"?
