Class Experience

Hello, Mathematicians! In this one-time math class, we will use the traditional vertical method for learning subtraction regrouping with 2-digit and 3-digit numbers. We will begin by learning the importance place value understanding plays in laying a solid foundation for understanding math. We will discuss terms used in solving traditional vertical subtraction problems, like borrowing and difference. This will be an interactive math class with students using their own whiteboard to solve problems during class. Learners will be encouraged, but not forced, to answer questions and share their work and thought process during class. The intention is for students to learn the skills in a safe, positive, encouraging classroom environment. This class is intended for beginners of subtraction regrouping, but students enrolling should already have a general grasp of place value (ones, tens, hundreds) and recall of basic math facts for subtraction from 20.  I strongly recommend students learn vertical addition with regrouping BEFORE they are introduced to vertical subtraction with regrouping. We will not work on advanced regrouping skills, such as subtracting across zeros. Let's learn to regroup, Mathematicians!

*It will be very helpful if the learner already has a very basic understanding of how Zoom works, like how to make sure their name shows in their camera box in class (so we know who they are) and how to mute themselves when not speaking to avoid a lot of background noise from multiple learners at once in the classroom.

Learning Goals

The goal of the class is for students to use the traditional vertical method to solve subtraction regrouping math problems.

Other Details

Parental Guidance
I strongly recommend students learn vertical addition with regrouping BEFORE they are introduced to vertical subtraction with regrouping. While students may not totally master ALL the skills related to regrouping subtraction in one 45-minute math class, through repeated practice and implementation of the skills taught in class, they will be masters of vertical subtraction in no time!
Supply List
The learners will need to bring a whiteboard, dry erase pen, and eraser to class.
External Resources
Learners will not need to use any apps or websites beyond the standard Outschool tools.

Teacher expertise and credentials
I have been a classroom teacher for 26 years and use this vertical regrouping method successfully, along with other various strategies for solving math problems, to help build the bridge between concrete and mental math mastery.
