Elapsed Time Word Problems Using a T-Chart

The video tutorial teaches how to solve elapsed time word problems using a T-chart. It begins with an introduction to the concept and reviews common mistakes in time counting. The tutorial then demonstrates solving a word problem about school dismissal time and calculating the time difference between two bedtimes. The lesson concludes with a summary of the key points covered.

What is a common mistake people make when counting time after 12:00 PM?

• They say 12:00 AM instead of 12:00 PM.
