Daniela Seves:She did a very simple and clear exercise but had some spelling mistakes that can confuse the students.
Nataly Echeverria:I didn't seem to understand the purpose nor the structure of the activity,I think it wasn't very clear in the instructions  and a bit confusing.
Sebastian Andrade:The exercise was pretty good but the instructions weren't clear.
Camilo Salazar:I think it needs more instructions,is kind of too open or wide,there's no specific learning.
Estephanie Carrasco:I think her's is the best,is clear in the topic and probably is done for 12th grade students,maybe a better organized exercise plan.
