Grade 7
Math curriculum
By the end of grade seven, students are adept at manipulating numbers and
equations and understand the general principles at work. Students understand
and use factoring of numerators and denominators and properties of exponents.
They know the Pythagorean theorem and solve problems in which they compute
the length of an unknown side. Students know how to compute the surface area
and volume of basic three-dimensional objects and understand how area and
volume change with a change in scale. Students make conversions between
different units of measurement. They know and use different representations of
fractional numbers (fractions, decimals, and percents) and are proficient at
changing from one to another. They increase their facility with ratio and proportion,
compute percents of increase and decrease, and compute simple and compound interest.
They graph linear functions and understand the idea of slope and its relation to ratio.
