The Number System
In this unit, students will explore different representations of rational numbers, such as fractions, decimals (with finite or repeating digits) and percents. Students will extend addition, subtraction, multiplication and division to all rational numbers. Students will use rational approximations of irrational numbers to estimate their values, compare sizes and approximate their locations on a number line.
This unit was developed from the Common Core State Standards. For more information download the unit guide (on the right) where the specific content standard is identified. There may be other CCSS that align to the activities as well that are not referenced on the guide.
