Elapsed Time on a Number Line

The 3-hop method that stops finger counting — anchor charts, task cards and blank templates for grades 3 and 4.

Why the number line wins

Most elapsed-time mistakes come from counting on fingers and losing the hour along the way. Time behaves like distance: mark the start, hop the whole hours, then count the leftover minutes. Students stop guessing and start seeing the gap.
