Day 47: Math 6 - Writing Equations / Math 6+ - Graphing Linear Equations

Math 6 students worked with Lesson 4.3: Writing and Solving Equations with Addition and Subtraction for a second straight day. The focus today was on writing equations from real-world problems.

Math 6+ students worked with slope-intercept form and how to graph linear equations.

Standards addressed in class today:

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.
• Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers.

Math 6+:

• Solve linear equations in one variable. 
• a. Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers). 
• b. Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.
