Elapsed time is always a tricky topic for my third graders. I use this document with these awesome ETA hand2mind Elapsed Time Rods
to help students in math groups, centers, and independent work.
I print and laminate this document to use as a visual aid for students during centers and independent work. I also print these at in a smaller size, under printer settings, and allow students who need the visual support to keep them in their journals. You could even post it as a reference poster. It's also available in two formats (see in preview).
I always appreciate your support and your feedback. If you have any questions, suggestions, comments, or personal-resource requests please email me at: firstname.lastname@example.org. Enjoy, teacher tribe!
