Now you want to put these adjectives into practice so they will be better understood. Students may practice first with objects, and then with themselves. Take a book and demonstrate by saying "este libro" (this book). Next, point to a book near to a student and say "ese libro" (that book). Now take two or more books and say "estos libros" (these books). Now point to some books near a student and say "esos libros" (those books). Now you are ready for your students to try the feminine forms. Point to a chair and say "esta silla" (this chair), then point to two or more chairs and say "estas sillas" (these chairs). You are now ready to do the same exercise to indicate "that chair" and "those chairs" by using "esa silla" and "esas sillas." Your students can practice using different objects. You can also practice using the students with sentences like:
Este muchacho se llama Antonio y ese muchacho se llama Juan.
This boy’s name is Antonio and that boy’s name is Juan.
Esta muchacha se llama Ana y esa muchacha se llama María.
This girl’s name is Ana and that girl’s name is María.
Estos muchachos son muy inteligentes y estas muchachas también.
These boys are very intelligent and these girls also.
Esos muchachos son muy simpáticos y esas muchachas son muy simpáticas.
Those boys are very kind and so are those girls.
