You can have students use the cards to sort words as having OA or OW, sort by word families, spell out the words with the letter cards, or use the sorting mats for a lot of different sorts!
There are also a lot of other things you can do with these cards like I show in the above blog post. :)
* 34 OA Picture Word Cards
* 29 OW Picture Word Cards
* Sorting Mats (oa, ow, -oat, -oast, -oad, -ow)
* Black letter cards to build the words with as well as an option for vowels in red.
