Unit 5

Percent, Ratio, and Rate

"In this unit, students will extend their knowledge of percents to include percents between 0% and 1%, greater than 100%, and fractional percents. They will represent such percents using grid paper and will translate between percents, decimals, and fractions. Students will continue their previous work with part-to-part and part-to-whole ratios to express ratios as fractions and percents. They will also explore three term ratios. They will express ratios as fractions and percents. Students will be introduced to rates. They will express rates using words or symbols and identify rates from real life contexts, recording them

symbolically. Students will solve a variety of problems involving percents, ratios, rates and proportional reasoning. Sales tax and discounts, test scores, sports statistics, weather reports, public opinion surveys, nutritional labels, currency conversions, interest charges, commission, speed, fuel consumption, heart rate, and determining the better buy all involve an understanding of percents, ratios, rates and proportional reasoning. A strong understanding of these concepts is necessary for students to make sense of these situations in their daily lives." - Grade 8 Curriculum Guide
