Bits and Pieces I

(University of Michigan Overview)
Concept with Explanation
Selected Homework from ACE
In Bits and Pieces I students will investigate and make sense of rational numbers and operations with rational numbers. The investigations in this unit will help students to:

• Build an understanding of fractions, decimals, and percents and the relationships between and among these concepts and their representations;
• Develop ways to model situations involving fractions, decimals, and percents;
• Understand and use equivalent fractions to reason about situations;
• Compare and order fractions;
• Move flexibly between fraction, decimal, and percent representations;
• Use benchmarks such as 0, 1/2 , 1, and 1/4 to help estimate the size of a number or sum;
• Develop and use benchmarks that relate different forms of representations of rational numbers (for example, 50% is the same as 1/2 and 0.5);
• Use physical models and drawings to help reason about a situation;
• Look for patterns and describe how to continue the pattern;
• Use context to help reason about a situation; and
• Use estimation to understand a situation..
