A mathematics chart for 8th grade students should provide fundamental math rules and steps needed to solve linear equations and geometrical functions. By this time, an eighth grader should have mastered the following mathematical concepts:
Helpful information to include on math chart for 8th grade students needs to prompt the student rather than supply the student with too much information.
Although each U.S. state has slightly different educational requirements concerning what instructors need to teach public school students, an 8th grade math chart should offer the following information:
Other useful exponential concepts to put on the chart include exponents with fractional and decimal bases; power rule; relationship between square roots and squares and simplifying exponential expressions.
How to solve linear equations involving one variable.
Other algebraic information relevant to 8th grade math includes representing a linear function on a simple graph; solving linear equations involving multiplication or division; determining the y intercept and slope of a linear function on a graph and using linear functions to solve multi-step word problems.
A good simple word problem to practice using linear equations is:
70 less than 4 times a number is equal to the number. Find the number.
The equation for this statement would be written 4 times an unknown number x minus (less than) 70. Numerically, the equation would be written this way: 4x – 70 = x
Math chart information useful to 8th graders should include:
Provide examples showing how to find statistical means, medians and ranges
Provide examples showing how simple probability works, such as what is the chance that a die will land on any number one through six? Because six possible ways exist for the die to land on one of these numbers, the equation would be 6/6 and the answer would be 1. Remind students on the chart that all probabilities are either “0” or “1”, which is then converted to a percentage.
Other useful statistical information to place on a mathematics chart for 8th grade students include types of graphs (box, line, scatter, etc.); what a Venn diagram is and solving problems with permutations and combinations.
