When searching for a learning objective tool, teachers should look for open source tools that are easy to use and engaging for students. Two such tools I found are:
Class Tools– a free site for teachers to create games, quizzes, activities and diagrams. This site can be used to create review games or provide tools for assessment differentiation.
What 2 Learn-a free site to create study games. Simply choose one of the games you would like to make and modify it with your information.
