Mastering Contractions will help your students understand the patterns and rules for writing contractions. It's perfect for those children who can match "didn't" to "did not" but then proceed to write "didi'nt" on their papers. :)
While there are lots of match-the-contractions activities available, I wasn't able to find any that teach children the patterns and rules for spelling and writing contractions. I created this product for use with my class and was very pleased with the results. I hope you enjoy using it with your students!
