The word pattern cycles last for 10 days. After every 4th word pattern cycle, my class participates in a class-wide pattern study on the same skill. This skill is based on word structures or meanings (like compound words, posessives, etc…). These units can be swapped in or out based on need.
Just as we celebrate the end of a reading or writing unit, we also celebrate the end of a spelling unit! The first unit is celebrated by making a class book with our word-study goals for the year. Some units will be celebrated with special projects and the last unit is celebrated with a class-wide (or grade level-wide) Spelling Bee!
