This is an open-ended worksheet designed to be used in multiple subject areas. The idea is this -- students list 5 things in a given category. The category is left blank for you as the teacher to fill in or allow it to be student driven.
I can see this worksheet being used in one subject area or many subject areas throughout the day. Examples: Give me five even numbers, give me five compound words, give me five character traits of the main character, etc.
