Day 38: Math 6 - Write and Evaluate Algebraic Expressions / Math 6+ - Write and Solve Inequalities

Students in Math 6 reviewed their evening practice from last night before completing the Lesson 3.5 Online Assessment.



Math 6+ students continued their partner work for writing and solving inequalities from the previous day.



Standards addressed/assessed today in class:
  • Math 6: 
    • Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. For example, describe the expression 2 (8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.
    • Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). For example, use the formulas V = s3 and A = 6 s2 to find the volume and surface area of a cube with sides of length s = 1/2.
    • Write expressions that record operations with numbers and with letters standing for numbers. For example, express the calculation "Subtract y from 5" as 5 - y.
  • Math 6+:
    • Fluently divide multi-digit numbers using the standard algorithm.
    • Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.
    • Write an inequality of form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.
