Grade 7 Unit 1 Rational Number Operations Assessment Plan 7th Grade ISBE Unit Map Standards Addressed: Apply and extend previous understandings of addition and subtraction to add, subtract, multiply, and divide rational numbers. 7.NS.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 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. 7. NS.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, 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. 7. NS.3 - Solve real-world and mathematical problems involving the four operations with rational number. Unit Supporting Standards (Supporting standards should be used to create a context for Unit Standards, and should not be explicitly taught) Use properties of operations to generate equivalent expressions. 7.EE.2 - Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, a +0.05a = 1.05a means that “increase by 5% is the same as multiply by 1.05.” 1 Transfer: Students will apply concepts and procedures for representing, interpreting, and solving realworld and mathematical problems involving operations with rational numbers. Ex: 2/3 of the students at our school have cell phones. 1/4 of those students have smartphones. What fraction of the students with phones have smartphones? Ex: Sarah has $135 left in her checking account after writing checks for $25, $32.50 and $18.40. What was her balance before she wrote the checks?
