If you are using the Leveled Literacy Intervention BLUE System by Fountas and Pinnell, then you will appreciate having these word cards. The cards are in a larger format than the ones found on the CD and also have a blue background to help you keep your word cards organized. This resource also comes with the cards in black and white. If you are using multiple intervention systems from LLI, then you will appreciate having the background colored blue to keep you organized. The lesson number is also in smaller font on the word cards. You can use these word cards on a word wall, in pocket charts, or as flash cards. Just laminate and you are set!
