Big Ideas:
• Connections, Equivalence, Patterns, Relationships

Students will be able to...

• Use number lines to conceptualize the value of fractions and to compare and order fractions with landmark numbers, such as 0, ½, and 1.
• Use a number line to compare and order fractions with different numerators and different denominators, and to justify equivalence of fractions. (Limit to denominators of 2,3,4,6,8,10, and 12.)
• Use a number line to base explanations and to justify reasoning about the value of fractions.
• Compare fractions and express their relationships using the symbols <,>, or =.
• Compare two fractions with different numerators and different denominators by creating common denominators and numerators.
• Apply understanding of fraction equivalence and ordering to solve simple word problems requiring fraction comparison.
• Use a multiplication chart to conceptualize why the numerator and denominator can be multiplied by the same number to create an equivalent fraction.
• Use the principle of fraction equivalence (both the numerator and the denominator may be multiplied by the same factor to produce an equivalent fraction) to recognize and generate equivalent fractions.
• Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100. (For example, express 3/10 as 30/100, and 3/10 + 4/100 = 34/100)
• Explain equivalence of fractions using drawings and models. More specifically, explain why a fraction a/b is equivalent to a fraction (nxa)/(nxb) by using visual fraction models, with attention to how the number and size of the parts differ even though the 2 fractions themselves are the same size.
• Identify or describe errors in solutions to multi-step problems and present correct solutions involving fractional comparisons.
