Spelling Bee
Most of the work for the bee will need to be done by students on their own time. There are suggested lists for studying. I would suggest studying the Level 1 and 2 lists and move up to level 3 from there. These lists don't include all of the possible words, but they are a good start for studying.
Students have a new way to study by downloading Word Club for free in the App Store or Google Play Store. Choose from five spelling play modes and three vocabulary play modes. Track your progress as you conquer the School Spelling Bee Study List and Words of the Champions, the recommended study resource for classroom, school, regional qualifier, and regional spelling bees!
