Elapsed Time
It’s 11:37, and your friend is picking you up at 3:15 for your annual vacation. Quick, how long do you have to pack and get ready? This is often not easy for young students to master because they have spent all of their time gaining number sense in a base-10 system, and time is measured in unusual ways: 60 minutes per hour, 24 hours per day, two 12-hour cycles per day.
In the Elapsed Time Gizmo, students discover different strategies to find elapsed time in various situations. They explore elapsed time using “on-the-hour” times, and then move on to calculate elapsed times that include minutes. As students use the Gizmo, they will learn to convert AM/PM times to the 24-hour clock and use borrowing to find elapsed times with minutes.
There’s also a fun follow-up activity in the Gizmo’s Teacher Guide—an elapsed time contest! Students form teams of three and mimic the Gizmo. Two teams compete against each other to solve problems that ask them to calculate elapsed time, start time, or end time. The winning team gets one point, and the first team to five points wins!

Everybody's Talking About Gizmos
Hello, Ms. D. I apologize about emailing you during the weekend, but I couldn’t wait to tell you. Gizmos is so much fun, and I absolutely love it. I actually learn something and I like the fact that it is interactive. Thank you so much for making us do Gizmos.
- Gizmos Student, American International School, Abu DhabiI really love Gizmos as they help students grasp difficult concepts that can’t always be seen. They make abstract ideas come to life.
- Gizmos Teacher, Foothills School Division, Alberta, CanadaAnother great feature of Gizmos is that I can manipulate them to accomplish my desired learning outcomes for my students. Sometimes I take a Gizmo that is meant to be an entire lab, and I cut it down into a smaller, briefer activity. But, other times, I combine some of the smaller labs into one and have the students access the various Gizmos from the class home page for a bigger assignment. In that way, Gizmos are always able to accomplish my desired outcomes.
- Teacher, Stuarts Draft High SchoolAny time I’ve used Gizmos, my students have a deeper and more meaningful experience with their learning. It leads to more inquiry and great classroom discussion!
- Grade 3 teacherAs a teacher, this platform is a time saver for me, as there are ready-made tasks and STEM hours, but I also like that I can modify assignments at any time.
- Teacher, Wicomico County School DistrictGizmos associated with higher performance on NGSS-aligned state science assessments
Data from more than 22,000 students at over 115 schools found that higher Gizmos usage led to a higher likelihood of meeting or exceeding proficiency on two different state science achievement tests.
