Resource Instructions

1.  Teach and model the steps in finding elapsed time using the first slide in the attached Smart Board activity.  The students will count the hours first, and then the minutes when finding elapsed time.  The arrows on the digital clock can be clicked to change the analog clock.  This will show students what happens to the clock as hours and minutes go by.  Move the rectangle in step three to show the answer.  Students can follow along with a print out of the steps using the attached student sheet.

2.  Use the elapsed time practice website on slide 2 for individual practice.  With this site, students move the clock hands on the smart board to help them through the steps in finding elapsed time.  They can move the hour hand, then the minute hand.  Students not at the smart board, can be calculating the elapsed time on paper.

3.  Have students practice with a teacher-made worksheet.


1.  The students can create a schedule using starting and ending times to plan a trip to the zoo.  You can find zoo maps on certain zoo websites to help students choose exhibits.  I use the Bronx Zoo map printed from their site. 

2.  Have students create a video with a set time limit that can be used for new students.  They can plan out what should be included in the video to welcome new students and acclimate them to the school, and how long each segment will take.  Then video tape them and use the video throughout the year when new students begin.

3.  Use the attached math websites to continue practicing finding elapsed time.

Hi Laura, I love your lesson, especially the handouts. I don't have the Smart Board software so I couldn't see the first asset. Do you know if it will work on other interactive whiteboards other than Smart Boards? Stav

I have been trying to download this activity but it will not download. Is there something wrong with the link? I would really like to have this. My students are having a hard time with elapsed time.
