Open Ended

I count ___ squares

Learning & Habit Objectives

Learning: I will express equivalent expressions in scientific notation & standard form

Habit: I will attend to precision

Success Criteria

• I know the correct format of scientific notation

• I can write a standard number in scientific notation

• I can rename from scientific to standard form

Notebook: Scientific Notation Format

Scientific notation is an efficient way to express very large or very small numbers. The format consists of a number in the ones place times a power of 10. There may or may not be decimal digits.
Examples:

 $2.4\times10^5$         $5\times10^6$  

Multiple Select

Select ALL that show the correct format of scientific notation:

• $6.5\times10^2$

• $0.03\times10^7$

• $3.0\times10^7$

• $7.125\times10^3$

• $32.1\times10^2$

Notebook: Rename from Scientific to Standard Form (will do in class)

 $3.25\times10^4$  

Notebook: Rename from Standard to Scientific (will do in class)

52,400

Multiple Choice

Exit Ticket B: Select the correct scientific notation equivalent to 4,370,000

• $43.7\times10^5$

• $\left(4\times10^6\right)+\left(3\times10^5\right)+\left(7\times10^4\right)$

• $4.37\times10^6$

• $4.37\times10^4$
