If you've never seen it before, www.RocketSpelling.com is an incredibly fun spelling website. My 3rd graders love it! The idea is that they have instructional videos (also found here: https://www.youtube.com/c/RocketSpelling) that go with practice challenges. Kids can work up to harder and harder levels at their own pace. All of the data is tracked and can be viewed in a teacher account. This can be your entire spelling program or, if you're committed to something else, is a great supplemental resource. Highly recommended!
