Math is a skill that all students need and basic math facts are keys to success! But for some students, math is more difficult and frustrating. Students who have more difficulty learning basic math facts sometimes have more difficulty applying basic skills to higher-level thinking when they get older and they may have more difficulty solving real-world math problems. These math quiz cards and power pens allow for students to practice skills independently that have been taught and allow them to do so in a fun way! Power pens give instant feedback for students so they know when they have gotten the correct answer.
