Freebie: Adding on an Open Number Line

We are teaching several common core strategies to our third graders this year to help them add and subtract.  One of those strategies is using an Open Number Line.  This math has definately been challenging as we attempt to stay one step ahead of our students.  With no text books and little practice material, we are creating our own.  Here is a homework sheet we used to check student understanding after our whole group instruction. (Clipart from 3am Teacher). For a full packet of "How-To's" to distribute your parents, or just use yourself, see the blog post just before this one on September 3rd.

  2. We use a curriculum from Pearson called Investigations which teaches strategies similar to that one. If you ever need anything please let me know. I love teaching math this way! Here is a link to a set I made for my parents and my students on adding by place and adding one number in parts:

  3. Yes, Investigations is great! We have one set per grade level, and use that as a teacher resource.
