Here's a little game to practice reading cvc words with short u. It's easy to differentiate, with 30 red-bordered cards having basic cvc words, and 20 green-bordered ones having cvc words with an initial blend or digraph - use the sets separately, or combine them! There's also a page of blank cards that you can program with your own skills, whether it's number facts, sight words, content area vocabulary, or whatever your need. Click on the cover to come to my blog and get your own!
Happy Teaching!
