Suitable for Grades: 8th Grade, Algebra I, IM 1
CCSS: 8.EE.A.4
CCSS Description: Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities (e.g., use millimeters per year for seafloor spreading). Interpret scientific notation that has been generated by technology.
Add and Subtract in Standard Form WORKSHEET DESCRIPTION
This worksheet focuses on adding and subtracting numbers in standard form.
In Section A, students are asked to fill in the blanks, requiring them to adjust numbers so that they remain equivalent as the powers of ten change.
Section B introduces students to adding and subtracting numbers in standard form when the numbers share the same power of ten.
The worksheet then presents two methods for performing these calculations: converting numbers into their ordinary form first or adjusting the numbers to have the same power of ten. Students are required to use both methods to solve problems and then decide on the most efficient or preferred approach.
