Teaching students the WHY before the PROCEDURE when learning a new math concept is essential. I am a firm believer that teachers owe it to their students to teach them multiple ways to solve math problems. We all learn concepts in different ways and math is no different. We are now into our subtraction with regrouping unit this week. This is a skill that can be taught using a variety of strategies. My favorite strategies are provided through the use of video tutorials below. Be sure to grab the freebie and links to subtraction with regrouping resources!
At the beginning of our subtraction with regrouping, we ALWAYS start with manipulatives. Personally, I prefer the unifix cubes over the base ten blocks because the unifix cubes can be pulled apart when there is a need to regroup. Take a look at how I use unifix cubes to teach subtraction with regrouping.
Don’t forget to grab your FREE Place Value Mat that you saw used in the video tutorial above. A quick tip that my students find helpful is to have your students highlight the ones place. This will draw their eyes to the part of the problem that needs to be solved first.
I have included four more strategies that I use to teach my students subtraction with regrouping. You just never know what is going to “stick” with them!
