Here is what we did in math today!
We subtracted on an "open number line." This is just like what we did for addition, only our numbers are being subtracted, instead of added.
Please understand that these mental math strategies are not going to be tested on the Unit Test in a couple of weeks. I am teaching these strategies to students so they can choose methods that work best for them. If they are struggling with one method, then they should choose the method that works best for them!
If you have questions, please let me know!
