Don't let subtraction bully you! Forget all the crazy borrowing and carrying? There is a secret subtraction trick that the smart kids don't want you to know. This fast math trick will help make subtraction rules easy and fun! This is a great subtraction method for students of all ages!

Second, have the students do the decomposing before they do the subtraction (Method A). Go through the entire number, checking whether you need to decompose (regroup) for each place. Then students can do the next two steps: decompose (regroup) and subtract. Blog post from AIMS Education

Now teachers around the country are using this method!
