Day 37: Math 6 - Evaluate Algebraic Expressions / Math 6+ - Write and Solve Inequalities

Math 6 students continued their work from last Wednesday with Lesson 3.5: Write and Evaluate Algebraic Expressions. The evening practice from the long weekend was reviewed and discussed. Students were then assigned partners to begin work on their evening practice.

Math 6+ students were paired up and asked to research a multi-step inequality word problem online that they could solve. This problem was then recorded on chart paper and displayed in the classroom. Each partnership then presented their problem to the class. Partners modeled the solution to the students using the ActiveBoard.

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.
