How To Teach Right-Brained Addition & Subtraction Vol. 2
This User Guide is designed to give you a birds-eye view of the purpose of this book, outline the primary skills the students will gain, and provide a synopsis of those skills and how they differ from traditional approaches to adding and subtracting multi-digit numbers.
Many students who struggle with adding and subtracting numbers larger than one digit have trouble because they are not familiar with their math facts, they get lost when trying to follow the steps to solve a problem, or they are unable to remember those steps to begin with. Very often, also, students are so focused on remembering the steps to solve the problems that they don’t focus on, or maybe didn’t ever understand, what is actually happening in each problem.
Another barrier to success for these students is that it is fun for almost no one to learn, remember, and use steps. What IS fun and engaging is solving a problem when you understand the problem and feel competent to solve it.
The method this book lays out solves all these problems by simplifying the procedure and by avoiding the need to add numbers whose sum is greater than 10. The book also supplies ample hands-on and tactile/visual practice that shows the students what is happening so they can understand the point of the work.
These differences in approach are transformative for students who have struggled with math.
What follows is a concise outline of the book
Hints for success
- Show the action (what is happening) in the problem we are solving. This will help children remember what to do to solve a similar problem in the future. This book does this for you.
- Allow children to practice the action and then settle into the method of solving the problem that works best for them. There is ample opportunity for hands-on practice in the book.
3 concepts to understand & teach
- What does place value mean?
- What does it mean to make a ten?
- What does it mean to take from ten?
1. WHAT DOES PLACE VALUE MEAN?
What follows are the basic principles of place value:
“In this town there are different offices for different numbers of people. There is a Ones Office, a Tens Office, a Hundreds Office, and so forth.
*HINT: When making a ten, always start with the largest number and take what you need to make a ten from the smaller number. In this way, you will only ever need to add 6+4, 7+3, 8+2, or 9+1. You will also only ever be taking a 1, 2, 3, or 4 from another 1 digit number, which will go a long way toward making multi-digit addition & subtraction super kid friendly.
3. WHAT DOES IT MEAN TO TAKE FROM TEN?
What follows are the basic principles of taking from ten:
To sum up. Using this approach children will only need to subtract 1-digit numbers from 10 and will only need to add 1-digit numbers that equal a number smaller than 10.
Right-Brained Addition & Subtraction, Vol. 2 details step-by-step exactly what to do, how to teach these concepts, and contains all the hands-on activities and student worksheets you will need.
