CC.7.EE.1 Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.
Add and subtract linear expressions with rational coefficients. Apply the distributive property to factor and expand linear expression and rational coefficients. CC.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 + 0.05 a = 1.05a means that “increase by 5%” is the same as “multiply by 1.05.” Convert between verbal and algebraic expressions to help understand problem. Convert between verbal and algebraic expressions to help solve problem. CC.7.EE.3 Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations as strategies to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form. Convert between forms of rational numbers as appropriate. Use mental computation and estimation strategies to assess the reasonableness of answers to problems containing rational numbers. CC.7.EE.4 Use variables to construct simple equations or inequalities to solve real-world or mathematical problems. Solve equations of the form px + q = r and p(x + q) = r fluently, where p, q, and r are specific rational numbers. Solve word problems of the form px + q = r and p(x + q) = r fluently, where p, q, and r are specific rational numbers. Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem it solves. |
