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 mrsbiddison@gmail.com. Without further ado – here’s Tracey!

For this first ever guest appearance I have teamed up with Tracey from The Teacher’s Chair.

*Not*loving the memorizing,

*not*loving the formulas or algorithms,

*not*loving the feeling that everyone else seemed to understand this cut and dry subject while my mind was trying to make sense of it in different ways. Sadly, this was pretty much my sentiment throughout high school as well. Don’t get me wrong, I worked and I worked (and even got tutored at times), but I would have chosen to write an essay over solving for Pi any day!

*(there is enough math in this article without having to calculate ages)*…Here I am, a multiage teacher and math is perhaps

*ONE OF MY FAVORITE*subjects to teach. I have a classroom of first and second graders. For the past 5 years, I taught both grades in the same classroom. This year, as per our district (and new standards, curriculum demands and testing) we are splitting the grade levels for math. I teach the 2nd graders and my colleague in multiage is teaching our first graders.

*Open Number Line Strategy*. As a precursor for using this strategy, I have to stress the importance of students being able to count forward and backward by ones and by multiples of ten. Plenty of time should be spent early in the year working specifically with the 100s chart. Students should then begin counting forward and backward with numbers from 100-1,000. I spent a lot of time with my students doing “warm-ups” of 1 more/1 less, 10 more/10 less, 100 more/100 less.

*(seen in the graphic below).*

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:

*“I love the new math strategies. I taught my parents and they like it better then old fashion math. My favorite is open number line. I started with not being very good at subtraction and then the open number line helped me learn it.”*

*I would love to hear how you are using math strategies in your classroom!*

Thanks, Amy…That was so much fun!

Great explanation of the strategy and the handouts are fantastic. I am really looking forward to expanding the use of alternate strategies in my classroom this year.

Great post! We just started implementing more Singapore Math strategies at my school this year too. Thank you for providing the parent information sheets. These strategies are new to us and also new to our parents!
