This fun, simple activity is great for centers or small groups. The activity includes 12 small cards. Each card has a sentence with the plural noun missing. There are 3 options at the bottom of the card for how the plural noun could be spelled, one is correct. Students pinch the one they feel is correct and turn it over to look for either smiley face, sticker, or whatever you decide to place on the back for self checking. There's a recording sheet included as well. This is great for a quick review!
