  • Review place value and order of operations.
  • Remind students that our number system is a decimal system and it relies on groupings of 10s. Tell students that we also utilize a place value system, with the value of each digit depending on its position or place in the number.
  • Write "1,000,000" on the board and ask students to identify at least one other way this number can be written. Possible answers include: writing the words “one million” or 10 x 10 x 10 x 10 x 10 x 10.
  • Tell students that mathematicians created a shortcut for writing very large numbers, and that today they are going to explore this technique.
