Scientific Notation for Numbers Up to 12 Digits

Begin with Write Large Numbers in Scientific Notation, then reverse the skill with Read Scientific Notation in Standard Form. The two billions sheets work as extension practice for fast finishers.

Write 16 numbers up to 12 digits, like 90,000,400,000, in scientific notation. In scientific notation, a number is written as a factor from 1 to less than 10 times a power of 10: 52,000 = 5.2 × 10 4. The directions on the page read: Write each number in scientific notation: a number from 1 to less than 10 times a power of 10. Leave off zeros at the end of a decimal. An answer key is included.

Yes, both. We made it for 6th Grade place value & rounding, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with scientific notation. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

The first factor must be at least 1 and less than 10, and the second factor is a power of 10. 9.7 × 10 to the 8th power is scientific notation, but 97 × 10 to the 7th power is not.

Move the decimal point to the right as many places as the exponent and fill empty places with zeros. 2.5 × 10 to the 3rd power = 2,500, and 4.853644 × 10 to the 10th power = 48,536,440,000.

It is usually taught in 8th grade. These pages use only large whole numbers and positive exponents, which suits students who already know place value into the billions.
