A complete description of the middle school math Texas Essential Knowledge and Skills can be found at the Texas Education Agency web site. Some of the knowledge and skills emphasized in eighth grade are described listed below.
Specifically in eighth grade, students will:
compare and order rational numbers in various forms including integers, percents, and positive and negative fractions and decimals;
use appropriate operations to solve problems involving rational numbers in problem situations;
estimate and find solutions to application problems involving percents and other proportional relationships such as similarity and rates;
generate a different representation of data given another representation of data (such as a table, graph, equation, or verbal description);
predict, find, and justify solutions to application problems using appropriate tables, graphs, and algebraic equations;
generate similar figures using dilations including enlargements and reductions;
estimate measurements and use formulas to solve application problems involving lateral and total surface area and volume;
use the Pythagorean Theorem to solve real-life problems;
use proportional relationships in similar two-dimensional figures or similar three-dimensional figures to find missing measurements;
find the probabilities of dependent and independent events; and
draw conclusions and make predictions by analyzing trends in scatterplots.
