So I am excited to be trying out a new “feature” on my blog – Blog Swap Sunday. Think wife swap only way less drama! I swap blogs with another teacher blogger out to share new ideas and lessons for the classroom. I thought this would be a fun way to hear from other teacher bloggers out there. There are so many amazing teacher bloggers with so much valuable information to share. I know that I have learned so much from others that I have been able to take back and use in my classroom immediately. I thought this would be a fun way to hear from others and find new ideas. I am hoping to eventually make this a weekly feature. If you are interested in participating in Blog Swap Sunday leave me a comment or e-mail me at email@example.com. Without further ado – here’s Tracey!
For this first ever guest appearance I have teamed up with Tracey from The Teacher’s Chair.

Currently, we are “Comparing” by counting up from the subtrahend to the minuend. The comparing method for subtraction is generally my students’ preferred method, because it is much easier for them to count forward rather than backward on a number line.
Recently, during my adventures with the Open Number Line Strategy, I introduced my students to a game I made called, “Deep Sea Dive to Zero.” Throughout the game, students have the opportunity to use subtraction with an open number line. This game is especially good during the earliest “Open Number Line” lessons. You can get it for free right here:
