If your kids are like mine, half the time they lose their word sort cards by the second day. So, I put this together to keep my kids practicing their words until I could get them another copy. These words are a companion to the yellow level Words Their Way materials. These activities DO NOT replace the word sort activities. They are very important. Use with RF.2.3. Great with short and long vowels, blends, digraphs, r-vowel sounds, word work, word sorts, spelling, spelling program, spelling centers, word work centers, and purposeful practice.
