The last workbook on contractions helps kids practice rewriting phrases using an apostrophe to show that something belongs to someone. For example, in the sentence "The keys of the driver got lost," you can change "keys of the driver" to "driver's keys."

Using an apostrophe to show possession is easy once you know the trick. Add an apostrophe followed by "s" to the person or thing that owns something. For instance, instead of saying "the backpack of Emma," you can say "Emma's backpack." This makes sentences shorter and easier to understand.
