Rewrite Two Digit Subtraction
Are you working on the multiple ways to write subtraction problems? Here are some tips, resources and lessons to help you introduce and reinforce rewriting 2-digit subtraction.
1. Introduce on the board or with your digital camera...
82 - 64 =
2. Explain when working with regrouping, we find it easier to write the problems in this format.
| 82 |
| - 64 |
Also explain that students and adults alike are less likely to make mistakes when writing it this way.
3. Solve or have a student solve your example.
4. Continue with more examples as needed.
* Common mistakes to look for in student work, writing the digits in the incorrect column, for example, 46 in this problem instead of 64.
If you have not used graph paper in your classroom yet, I HIGHLY recommend getting some now. Your students will love working with something new, especially if you tell them they'll use it a lot in middle school or junior high school! It will help keep the tens in one column and the ones in another, until they can transition to any blank paper.
I have four resources in my store to help you teach, reinforce and review rewriting 2-digit subtraction problems.
