Scientific Notation and Comparisons

Mr. Baskins' tutorial covers representing large numbers on a number line, using scientific notation to label tick marks, and comparing large numbers. The lesson also explores the speed of light through various materials, emphasizing the benefits of scientific notation. Students are guided through exercises to reinforce their understanding.

What is the scientific notation for 9 million?

• 9 x 10^5

• 9 x 10^6

• 9 x 10^7

• 9 x 10^8

Where would 5 million be placed on a number line up to 10 million?

• At the midpoint

• At the start

• At the end

• Three-quarters of the way

Which is larger: 4 million or 75 x 10^5?

• Cannot be determined

• They are equal

• 75 x 10^5

• 4 million

How can you convert 124 x 10^6 to a comparable form with 2.3 x 10^8?

• Add two zeros

• Move the decimal two places
