Long vowels are difficult for little learners because they must determine which spelling is correct for each sound. Let these Snow Gnomes Long O Clip Cards help your students practice the correct spelling for the long O sound. This product features 24 clip cards which allow students to determine if the spelling includes o-e, oa, or ow to complete the word.
To make these cards self-checking, I would simply add a star or sticker to the back of the card. My students love the "fun clothespins" from the Dollar Spot at Target for these!
