Students are able to make sense of and work with rational numbers and real numbers, including numbers written in scientific notation and square roots. Students understand and can make sense of rational numbers that are both positive and negative. Students will understand and apply properties of exponents in order to simplify expressions. Standards Math Content Standards MAFS.7.NS.1: Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers. MAFS.7.NS.1.1: Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram. a. Describe situations in which opposite quantities combine to make 0. For example, a hydrogen atom has 0 charge because its two constituents are oppositely charged. b. Understand 𝑝 + 𝑞 as the number located a distance |𝑞| from 𝑝, in the positive or negative direction depending on whether 𝑞 is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts. c. Understand subtraction of rational numbers as adding the additive inverse, 𝑝 − 𝑞 = 𝑝 + (−𝑞). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts. d. Apply properties of operations as strategies to add and subtract rational numbers. MAFS.7.NS.1.2: Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers. a. Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (−1)(−1) = 1 and the rules for multiplying signed numbers. Page 2 of 28 Suggested Mathematical Practice Standards MAFS.K12.MP.1.1: Make sense of problems and persevere in solving them. What is this problem asking? Could someone else understand how to solve the problem based on your explanation? MAFS.K12.MP.6.1: Attend to Precision. Using precise vocabulary, explain how to simplify the problem. Looking at the two ways we solved this problem, explain why one way is more efficient than the other. Using precise vocabulary, explain how to simplify the problem. MAFS.K12.MP.8.1: Look for and express regularity in repeated reasoning. How could solving a simpler problem help with performing operations with scientific notation? What generalizations can you make about negative exponents? Instead of using the expanded form for exponents to solve problems, are there any shortcuts you’re taking to solve? Updated: August 8, 2014 Interpret products of rational numbers by describing real-world contexts. b. Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If 𝑝 and 𝑞 are integers, then (𝑝/𝑞) = (𝑝)/𝑞 = 𝑝/(𝑞). Interpret quotients of rational numbers by describing real-world contexts. c. Apply properties of operations as strategies to multiply and divide rational numbers. d. Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats. MAFS.8.NS.1: Know that there are numbers that are not rational, and approximate them by rational numbers. MAFS.8.NS.1.1: Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number. MAFS.8.NS.1.2: Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g. π², ). For example, by truncating the decimal expansion of √2 , show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations. MAFS.8.EE.1: Work with radicals and integer exponents. MAFS.8.EE.1.1: Know and apply the properties of integer exponents to generate 1 equivalent numerical expressions. For example, 32 × 3−5 = 3−3 = 33 = 1/27 MAFS.8.EE.1.4: Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities (e.g., use millimeters per year for seafloor spreading). Interpret scientific notation that has been generated by technology. MAFS.912.N-RN.2: Use properties of rational and irrational numbers. MAFS.912.N-RN.2.3: Explain why the sum or product of two rational numbers is rational; that the sum of a rational number and an irrational number is irrational; and that the product of a nonzero rational number and an irrational number is irrational.
