See if you can solve a WASL question

Published 9:00 pm Saturday, March 11, 2006

Here is one example of the type of WASL math questions students in past years have struggled with most:

Barbara invited five friends over to her home. All her friends liked her new calculator and wanted to borrow it.

After everyone left, Barbara realized she needed the calculator to finish her homework. She could not re-member to whom she had loaned it.

She remembered the following:

&nbsp &nbsp &nbsp She last saw the calculator at 6:40 p.m.

&nbsp &nbsp &nbsp Miguel left 15 minutes after Tom.

&nbsp &nbsp &nbsp Tom left 30 minutes before Kendra.

&nbsp &nbsp &nbsp Kendra left 5 minutes after Srey.

&nbsp &nbsp &nbsp Dan left 25 minutes before Miguel.

&nbsp &nbsp &nbsp The last person left at 7:00 p.m.

  • List the order and times in which people left.

  • Whom should Barbara call, based on your analysis of the information?

    Explain your reasoning using words, numbers, and/or diagrams.
