One strategy we using to teach addition is the open number line. This is a great strategy that transfers REALLY well to subtraction. The difference between an open number line and a closed number line is that an open number line has no numbers on it- students create and write the number line starting and ending at whatever number they need.
Parents are often VERY confused at all this "new-fangled" math as it is very different from what we learned as children. I created this handout to help teach parents.
It is part of a "How to Add on an Open Number Line" pack I created. The pages gradual teach adding with the open number line using multiples of 10 nad then moving on to adding with regrouping.
The description of this product is:
The open number line is a wonderful way to teach addition AND subtraction. However, we always start with addition first in our classroom.
This packet includes “how to directions” on page 4 for parents, but is also a reference sheet for teachers.
This packet gives students practice adding two digits with and without regrouping using a gradual release. Students begin adding only multiples of tens and gradually work to adding two digits with grouping.
This packet includes:
- How to Add Using an Open Number Line Directions
- Adding Two Addends that are Multiples of Tens with Hints
- Adding Two Addends that are Multiples of Tens Without Hints
- Adding with One Addend being a Multiple of Ten With Hints
- Adding with One Addend being a Multiple of Ten Without Hints
- Adding with Two Digits With Hints

I am working on several packs just like this- strategies for addition and subtraction BESIDES the traditional algorithm. I am currently working on a pack that uses the hundreds chart to teach addition with 1,2,3, and 4 addends!
