This product comes with 30 pairs of regular and plural nouns (i.e. one cup & five cups; one bag & two bags). So, you can use the pairs receptively (i.e. "Point to cup" or "Point to cups"). You can also use these nouns expressively because it also comes with 2 sentence strips ("I see one BLANK" and "I see (2,3,4,5) BLANK-s/z"). This is a great way to practice regular plural -s nouns for those students with grammar goals or students learning English who drop the plural -s marker! Enjoy!
