  2. Yes, Rosa met her goal. Possible response: I added all the minutes Rosa read together:
    40 + 30 + 37 + 22 + 34 + 43 + 47 = 253 minutes.
    Since each hour has 60 minutes, four hours is the same as 240 minutes. Since Rosa read 253 minutes, she met her goal and read an extra 13 minutes.

F. Elapsed Time

  1. Rosa set a goal to read for 4 hours each week. She used a chart to record the time she started reading and the time she finished reading for each day. She forgot to record the total time that she read each day. Complete the chart for Rosa.
  2. Did Rosa meet her goal for the week? Show or tell how you know.
