Scientific Notation
Number and Operations: Understand numbers, ways of representing numbers,
relationships among numbers, and number systems.
7.N.1.4 Read, write, and compare rational numbers in scientific notation (e.g., positive
powers of 10) with approximate numbers using scientific notation.
When teaching order of operations, focus on the students’ prior knowledge of place
value. The exponent tells them how many place values to move the decimal; when you
multiply, move the decimal to the right and when you divide they move the decimal that
amount of places to the left.
Teacher sample:
1,300
In scientific notation, a student would start at the right and count the place values to the
left until the whole number falls between 1 and 10. Scientific notation needs one whole
number and do not drop off any numbers with value.
1.3 x 10³ = 1,300
Examples:
140,500,000
Standard form is going from scientific notation back to a standard number.
Student Practice
Write the following numbers in scientific notation:
2,000
96,000
14,000
108,000
81,300,000
Student Practice Answers
The answer is C. There are 7 place values from the right to left to create a number
between one and 10.
