Did you have fun playing with the cave kids? You better remember the nouns you learnt along the way, because you’re about to be tested! ‘Know Your Nouns – I’ is a simple vocabulary review worksheet, meant to test how well third graders remember the vocabulary words in the ‘The Cave Kids’ and ‘The Message’ worksheets. All kids have to do is replace the words in bold in each sentence with the noun that means the same thing. Good luck, and have fun!
