Your students can practise adding the missing apostrophes to possessive nouns with this fun activity.   A selection of sentence cards are provided. Some of the cards have one apostrophe missing, while the others have two or three. There are a mixture of singular and plural possessive nouns.   Your students need to attach paperclips to the edges of the cards to show where the apostrophes should go. On the reverse of the cards, they are able to check their answers as rectangles are provided to show the correct locations.   This activity was designed to be played as a game with points scored for correct apostrophes. Instructions are included, as well as a helpful recording sheet. Alternatively, your students could use the cards without playing the game and still practise their knowledge of possessive nouns while getting immediate feedback.
