Today we went over the possessive pronouns "Mi, mis, tu, tus, nuestro(as), su, sus."  After reviewing the possessive pronouns I then handed out an exercise where the students were asked to cut up a sheet of paper with all of the possessive pronouns and a series of nouns and names of family members.  I then had a series of prepared phrases and they were then asked to create the phrases with the words.  We ran through a whole series of phrases using the possessive adjectives such as (Nuestros hijos son jovenes).  After about twenty minutes working with phrases from the exercise, we then moved on to a review of the interrogative words from the previous class and the "El Pregunton" song that we used on Monday.  The students knew that they were going to be given a mastery test on the interrogative words, and so after a quick review, they were given a 12 question mastery test.  I really like the format that Mrs. DaiZovi uses for mastery tests.  There is a test 'A' and a test 'B' format.  After taking the 'A' test they then exchange the test and it is graded by a peer.  After the peer grading those students with a perfect score are given a sticker.  Those that did not get a perfect score are allowed to take a second test 'B'.  Many students improve and get a perfect score and they are also given a sticker for mastery.  This gives great positive reinforcement to the students.  I am seeing the value of mastery testing because the students really are motivated to improve their scores.
