You just found a lucky 4 leaf clover! This crossword puzzle is on the phonetic skill of cl consonant clusters. There are 6 Across clues and 6 Down clues. To help students find the words a word list with 12 cl words is provided. You should be able to see those words in my preview. Granted, this will be difficult for 1st graders. It is probably best for you higher functioning 1st graders unless you want to do it together on a smart board or overhead. It should work well with 2nd, 3rd, or 4th graders. Let me know in your feedback.
