I told students they were going to learn about plural possessive nouns. I wrote an example of a singular and plural possessive noun phrase on the board. I drew arrows to show what belonged to someone or something. I explained that if the noun is singular, you simply add an apostrophe s like we did the day before. However, if the noun is plural and already has an s, the apostrophe is added after the s. I wrote a few more plural possessive phrases on the board and guided students in adding the apostrophe after the s.
I introduced a lesson on the SmartBoard to engage students physically. They had to write the answer on the board and had a chance to manipulate the SmartBoard. I found the SB lesson on the SMART Exchange website. They have a plethora of quality, ready-made lessons. One of the activities required students to touch a random set of moving pictures. When a picture stopped, students had to select the plural possessive noun phrase that matched the picture. To make it whole-class, I had students write the answer on their whiteboard. I was able to assess students real-time as they held up their boards for me to check. Then I would call on a student to select the correct answer. I called them randomly using Popsicle sticks, so each got a turn.
After the SmartBoard lesson, students returned to their seats to begin work on their practice sheets. The sheet contained ten sentences. Students were required to change the noun in the sentence to show ownership, then write the possessive noun and what it possesses. The sentence, The wolf tried to blow the three pigs houses down, became the pigs’ houses.
To close the lesson, I asked students to write what they recalled about possessive nouns on their whiteboards. Most student students wrote that possessive nouns show who or what owns something and an apostrophe is added before or after the s. Students who did not have the correct answer were able to see the correct response multiple times around the classroom as students held up their whiteboards.
