Day 42: Math 6 - Student-Teacher Conference / Math 6+ - Inequality Preparation

Math 6 students conferenced with Mr. Giomini one-on-one to discuss their Topic Three Post-test. While that was taking place, time was given to work towards or exceed the quarterly Khan goal of 33%.

Math 6+ students worked with a partner to complete a review activity in preparation for tomorrow's Topic Three Post-test.

Standard(s) addressed in today's lessons:
Math 6:

• Write and evaluate numerical expressions involving whole-number exponents.
• Write, read, and evaluate expressions in which letters stand for numbers. 
• 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.
• Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3 (2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.
• Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). For example, the expressions y + y + y and 3y are equivalent because they name the same number regardless of which number y stands for.

Math 6+:

• 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.
• Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.
