Mathematics Pacing Resource Document 5.AT.2 Standard: 5.AT.2: Solve real-world problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators (e.g., by using visual fraction models and equations to represent the problem). Use benchmark fractions and number sense of fractions to estimate mentally and assess whether the answer is reasonable. Teacher Background Information: Benchmark fractions help students know the value of fractions. Students need to know where fractions fall on a number line using benchmark fractions. Benchmark fractions are 1/4., 1/2, and 3/4 and 1. Students need to know that one whole is represented by fractions like 3/3, 4/4, etc. When comparing fractions, students need to say the fraction is close to zero, one-half, or one whole. Understanding this also helps when estimating sums and differences. Students should be able to explain that 3/4 + 2/3 is more than one whole because both fractions are more than one-half.

Teacher Background Information: The identity property of multiplication tells us that a number x 1 has a product equal to the number (itself). For example, 4 x 1 = 4. So when we multiply by a fraction that is less than 1 our product has to be less than the number we are multiplying the fraction by. For example, 4 x 1/3 = 1 1/3. The product (1 1/3) is less than the original factor 4 because the second factor (1/3) is less than 1. Conversely, when we multiply a number by a number greater than 1 (including fractions/mixed numbers) our product is greater than the original factor. For example, 4 x 5/4 = 5. The product (5) is greater than the first factor (4) because the second product is greater than 1.

Explain why multiplying a positive number by a fraction less than 1 results in a product smaller than the given number. Relate the principle of fraction equivalence, a/b = (n × a)/(n × b), to the effect of multiplying a/b by 1. Teacher Background Information: The identity property of multiplication tells us that a number x 1 has a product equal to the number (itself). For example, 4 x 1 = 4. So when we multiply by a fraction that is less than 1 our product has to be less than the number we are multiplying the fraction by. For example, 4 x 1/3 = 1 1/3. The product (1 1/3) is less than the original factor 4 because the second factor (1/3) is less than 1. Conversely, when we multiply a number by a number greater than 1 (including fractions/mixed numbers) our product is greater than the original factor. For example, 4 x 5/4 = 5.

Teacher Background Information: Fractions as parts of wholes: A fraction such as ¾ represents a whole which has been partitioned into 4 equal parts and 3 of those parts are being considered. Fractions as parts of a set: Uses a set of objects as a whole (unit). Without mentioning fractions students should have many opportunities to partition sets – background for both fractions and division. Fractions as division: This meaning comes from division 3 ÷ 5 and also the partitioning illustration. It is this meaning that needs to be understood to change fractions to decimal notation.

Indianapolis Public Schools Curriculum and Instruction Mathematics Pacing Resource Document 5.NS.6 Standard: 5.NS.6: Understand, interpret, and model percents as part of a hundred (e.g. by using pictures, diagrams, and other visual models). Teacher Background Information: Ratios, unit rates, and percents are critical tools for solving real-world problems. The term percent comes from the Latin expression meaning "per hundred". A percent is also defined as a ratio comparing one number to 100. So 56% is understand as a ration of 56:100 or the fraction 56/100 or the decimal 0.56. Depending on the context, quantities may be represented as a ratio, fraction, decimal, or percent. Baseball statistics are presented in the decimal form, measurements are presented as fractions or decimals, and weather data are referred to as percents (40% chance of rain.)
