When your student starts 8th grade math problems, you may suddenly feel like math class has gone beyond your ability to help. While recent core standards have changed the face of eighth grade math class, and you may not recognize some of the work coming home, there are resources you can use to provide the assistance your child needs. Sometimes, knowing what to expect can help. Here are some common questions you can expect to see on your child’s 8th grade math problems.
Linear Equations
8th grade math problems begin to introduce linear equations and systems of linear equations, which will be an important concept in later algebra classes. You can expect to see problems in the form of y = mx + b, and students should be able to know how to graph lines in this format, plotting coordinates using the slope (m) and y-intercept (b).
Here’s how this works. If the student sees y = 2/5x + 5, he is going to begin this graph by creating an x, y coordinate plane. The vertical line on the plane, the y-axis, is where graphing begins.
The student should then place a point at the y-intercept (5). From there, the student measures the slope, which is shown as a ratio of rise/run (familiar?). In this equation, the slope is 2/5. From the 5, the student should go up (rise) 2 and over (run) 5 on the coordinate plane, plotting a second point. Connect the points and extend the line to graph the equation.
Students will also be taught how to solve for one variable in a linear equation. For example, if they are given 3x + 1 = 7, they will know how to solve to get the answer x = 2.
Functions
In 8th grade, students will begin working with functions. Functions define an output that applies to every number placed into the function. For example, you may see:
f(x) = x+1
This function means that for any number (x) placed into the function, you will add one. So, if the student is asked to find the output or value of the function for 2, 4 and 6, the answer will be 3, 5 and 7 after each value is placed into the function.
