This product helps teach students the difference between an uppercase letter, lowercase letter, word and number. This skill is part of the Kindergarten Common Core. The product contains a sort with uppercase letters, lowercase letters, words and numbers, as well as an activity sheet to help students demonstrate their knowledge (and teachers to be able to assess student proficiency). The sort contains header / anchor cards to assist students in the sorting process. This activity can be completed as a whole group, or in a small group literacy center setting.
