MGSE6.EE.1: Write and evaluate expressions involving whole-number exponents.​

​

​

By Husna Farheen

​Base and Exponents:

​

Base: The base number tells what number is being multiplied.

​

Exponents: The exponent, a small number written above and to the right of the base number, tells how many times the base number is being multiplied.​

MGSE6.EE.2b ​Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. For example, describe the expression 2(8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.

​ Parts of an expressions

​

Terms: Parts of the expression

​

Coefficient: ​The numerical factor of a term that contains a variable

​

Variable: ​A letter that represent one or more Quantities

​

​Constant: A term without variable

Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when to specify a particular order (Order of Operations). For example, use formulas to find the volume and surface area of a cube.
