Learn · Illustrative Mathematics · Grade 6 · Unit 3
Short lessons you can play with. Convert units, find unit rates, compare speeds and paces, and find percents with tapes and double number lines, then check yourself. When you’re ready, practice in Rate Racers.
Six short chapters follow the unit’s lessons in order. Each step shows one idea with something to change, then a quick check. A wrong answer names the likely mistake and gives one more try.
Double number lines for rates and percents, tape diagrams split into tenths, coins for percents of a dollar, and benchmark percents as fractions.
Each chapter ends with a link to the matching station in Rate Racers, the practice game for this unit. Progress is saved on this device.
Lesson 17 (Painting a Room) is an open-ended project, so it works better in class.
