The Teach Your Children Math Well Percents, Ratios and Proportions module consists of 19 lessons. The first lessons cover practice in decimal point placement, reading and writing percents, writing percents as decimals, solving percents problems and word problems, writing decimals as percents and writing fractions as percents. The second part covers practice in writing ratios both as fractions and percents, solving ratio word problems, setting up proportions, and solving proportions word problems. Each lesson will take a student about 10 to 20 minutes to complete.
