The online math exercises for 7th graders cover a wide range of skills and concepts essential to the U.S. school curriculum. For example, exercises on operations with whole numbers and decimals allow students to complete missing expressions and perform a series of additions and subtractions of integers. These exercises help students better understand integers and arithmetic equalities.
Algebraic calculation activities are also well represented, with exercises aimed at developing and factoring algebraic expressions. These exercises introduce students to basic techniques of literal calculation, such as expanding an algebraic expression and factoring expressions. Additionally, the use of magic squares helps students start solving equations in a fun and interactive way.
In geometry, the exercises focus on calculating perimeters and areas of geometric figures such as circles and disks. Students learn to apply formulas to determine the perimeter of a circle and the area of a disk, reinforcing their understanding of geometric concepts.
These online exercises, corrected and varied, are a valuable supplement to the math curriculum for 7th grade. They allow students to practice independently and interactively, while consolidating their math skills through diverse activities.
