How this fits in

Adding, subtracting, multiplying, and dividing decimals is one skill in the Fractions & Decimals 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.
