How this fits in
Exponents and powers is one skill in the Pre-Algebra unit. Students read the unit lesson, then earn a bronze, silver, or gold medal on their last 10 answers. Medals never go down. A mastered unit comes back for review after 1, 3, 7, 16, and 35 days so it stays learned.
Practice exponents and powers until it sticks
Unlimited fresh questions, hands-on problem types, a tutor while you work, and a review schedule that keeps it learned. Free, no credit card.
