7. Solve linear equations in one variable.
One of the really nice things about math is that there's always one right answer. None of that wishy-washy, subjective, personalized, "What do you think?" stuff in math. Let English teachers deal with all that. In math, if an answer is right, it's right. That's it. The end. No questions asked.
Well… no, not always. Sometimes in math, there are no right answers and sometimes there are an infinite number of answers to a problem.
Make sure to clean your students' brains off the walls after their heads explode.
- 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).
- Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.
