Before Q3, ask students to circle every plural noun in the passage and decide whether it ends in s. This primes them to apply the apostrophe-after-s rule in questions 3 through 8 without confusing it with singular possessives.
- Leo read a sign near the crater. It said: 'The raptors__ den is close.' Which answer correctly fills the blank to show the den belongs to the raptors?
- Leo found a nest. It belonged to the herbivores. Fill in the blank: Leo found the __________ nest near the ancient fern.
- Leo wrote this sentence in his notebook, but it has a mistake. Fix it: 'The dinosaurs's footprints led straight to the meteor crater.'
