Unit 5 Lesson 21/22
In this cluster, the terms students should learn to use with increasing precision are laws of exponents, power, perfect squares, perfect cubes, root, square root, cube root, scientific notation, and standard form of a number.
8.EE.A.3 Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other.
8.EE.A.4 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.
Students use scientific notation to express very large or very small quantities. Students compare and interpret scientific notation quantities in the context of the situation, recognizing that if the exponent increases by one, the value increases 10 times. Likewise, if the exponent decreases by one, the value decreases 10 times.
Students understand scientific notation as generated on various calculators or other technology. They perform the four operations in which both decimals and scientific notation are used.
