I use these quizzes with the first grade Everyday Math curriculum unit on addition. Once a week, students take a different form of the quiz, timed for 5-10 minutes. Students who score a certain number correct each week get their name added to the "I have Fact Power!" poster in our classroom and are exempt from the following weeks' quizzes (many students opt to continue taking them). These weekly quizzes really motivate students to memorize and have quick recall of those pesky addition facts that are so important for all higher level math skills.
These quizzes can be used with any curriculum and also as drill practice, with manipulatives, or as homework. The title for each quiz can be easily changed on Word when downloaded. Each quiz has 50 problems for easy scoring and are written in vertical form.
