Concept with Explanation
Selected Homework from ACE
Bits and Pieces II was created to help students make sense of one aspect of rational number: fraction operations. The investigations in this unit will help students to:

• Use benchmarks and other strategies to estimate the reasonableness of results of operations with fractions;
• Develop ways to model sums, differences, products, and quotients with areas, strips, and number lines;
• Use estimates and exact solutions to make decisions;
• Look for and generalize patterns in numbers;
• Use knowledge of fractions and equivalence of fractions to develop algorithms for adding, subtracting, multiplying and dividing fractions;
• Recognize when addition, subtraction, multiplication, and division is the appropriate operation to solve a problem;
• Write fact families to show the inverse relationship between addition and subtraction, and between multiplication and division;
• Solve problems using arithmetic operations on fractions; and
• Look for and generalize patterns.

 Vocabulary
 Picture Vocabuary Equivalent Fractions:  Fractions that have the same simplest form. Hundredths Grid: a 10 by 10 grid reduce: to put a fraction isn simpler form reciprocal: two numbers whose product is 1. Easily gotten by 'flipping' the numerator & denominator. i.e. 2 * 1/2 = 1 Fraction:  Part of a whole number. Written in the form of a numerator and denominator Numerator:  The part of the whole being used Denominator: The whole of the fraction.  The number of equal pieces in the whole. Common Denominator: When two fractions have the same denominator. Used for addtion and subtraction operations.
