As a teacher, I love the ability for students to have a "smart practice." The word list is displayed and reviewed, then students take a practice test. They can see the words they will need extra practice on...and then they can do a smart practice on these words.
The words are practical, useful words to master!
My students use these words along with a spelling notebook so they can incorporate technology with the practice of pencil and paper work.
They can practice in the car, at home or at school.
A great way to learn the patterns and build a strong foundation in spelling.
