How Many Hundreds? How Many Total?

  • 1 Here are the numbers of postcards in six collections:

    174, 96, 98, 122, 113, 151

    • a. About how many hundreds of postcards are there in all? Circle the best estimate.

      400 600 800 1000

      How did you decide?

    • b. Add the numbers to find the exact total number of postcards. Use the standard algorithm.

  • 2 Here are the costs of 4 items at the grocery store:

    $1.31, $2.71, $1.97, $3.04

    • a. About how much do the 4 items cost? Circle the best estimate.

      $7.00 $8.00 $9.00 $10.00

      How did you decide?

    • b. Add the numbers to find the exact cost of the 4 items. Use the standard algorithm.
