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 seventh grade are described below.
Specifically in seventh grade, students will:
convert between fractions, decimals, whole numbers, and percents mentally, on paper, or with a calculator;
use addition, subtraction, multiplication, and division to solve problems involving fractions and decimals;
select and use appropriate operations to solve problems and justify the selections;
estimate and find solutions to application problems involving percent;
estimate and find solutions to application problems involving proportional relationships such as similarity, scaling, unit costs, and related measurement units;
formulate problem situations when given a simple equation and formulate an equation when given a problem situation;
use critical attributes to define similarity;
graph reflections across the horizontal or vertical axis and graph translations on a coordinate plane;
estimate measurements and solve application problems involving length (including perimeter and circumference) and area of polygons and other shapes;
estimate measurements and solve application problems involving volume of prisms (rectangular and triangular) and cylinders;
make inferences and convincing arguments based on an analysis of given or collected data; and
choose among mean, median, mode, or range to describe a set of data and justify the choice for a particular situation.
