In this video, the instructor uses a graphics program to review how to subtract numbers and introduces how to re-group or borrow. The instructor also uses a number line. The video is suitable for elementary students. (18:26)

To find the difference between two numbers, sometimes you have to regroup, or borrow, from another number. Learn how to subtract using regrouping with this step-by-step, interactive video from StudyJams. A short, self-checking quiz is also included... with this link.[more]

In this video, the instructor explains how he uses mental math to subtract two four-digit numbers. In an easy conversational tone, the instructor uses the computer screen as his 'blackboard' and different colors to emphasis his points. This video is ...for upper elementary students[more]

Always begin the subtraction fun over there with the ones! When the number on top is smaller than below, it's time to go with the regrouping flow. This cute rap shows students how to borrow from the tens place to regroup. Students will enjoy this cut...e, catchy song. (1:18)[more]

This video shows how to subtract across a zero. The presenter explains how to borrow when subtracting with zeroes. She calls it "squaring off" and explicitly teaches how to do it. An example problem is then solved by a student using the same metho...d. (02:20)[more]

This video clip shows an alternative to regrouping or borrowing when subtracting. In this method, use estimation, counting, and mental math instead, which are skills normally learned before your learn how to regroup or borrow.

This video is an interactive whiteboard presentation demonstrating how to subtract using regrouping (called trading). The video demonstrates subtracting with 10 rods and unit cubes. Very visual learning model. Sound is a bit scratchy. (3:38)

This computer-animated video shows subtraction of multiple-digit numbers using regrouping. The problems appear on a black screen, and the narrator explains each problem step-by-step. ( 8:47)

Instructor uses manipulatives, math numbers, and a green marker to illustrate how to subtract when there is more than one zero in the top number. Suitable for grades 3rd and up.
(Note to teachers: The finder's problem with this video is that, whi...le visually it is an excellent help for students who need help with more than one zero in the top number, the original number is totally obscured while the instructor moves the manipulatives around.)[more]

In this video, a student shows how to subtract with regrouping using place value manipulatives. The student explains the problem step-by-step, writes the problem, and shows the problem with manipulatives. ( 1:34)
