Long division help

My students are really struggling with long division. Some of them have it. Some have trouble remembering where to put the numbers. Other are completely clueless. I have tried every method I can for instruction and practice.

what grade level? Are we talking a one-digit divisor, 2-digit divisor?

Maybe even post an example of what they are doing to give a better idea of how to try to help, if possible.

Long division and fractions are hardly ever their favorite thing to do in math

Long division was one the hardest math concept that I taught fourth graders. If there was anything that would make them cry this was it.

Have you tried using graph paper? An acronym for the steps?

I've done it on graph paper, with boxes, with the steps marked.
THey have a graphic organizer with the steps in their math notebooks.
It's 1 digit divisor, 2 and 3 digit dividend.

They remember the first step, and put the first quotient on top. Then they can usually follow the DMSB steps the first time. when they have to repeat it, they want to put the quotient underneath instead of up top.

Have you seen the app, PhotoMath? The student takes a picture of the actual problem and is walked through the steps. It could be a useful homework helper.

My niece-in-law shared it with me this weekend. It's been helpful for the twins who are in 8th grade.

We act out the steps of division before we begin.
Divide- stand up with your arms outstretched to make the bar. Punch above and below to make the dots
Multiply- make an X with your arms
Subtract- arms outstretched again
Compare- make a C with your arms
Bring it Down- wiggle to the floor

Then, I write the problem in black. Trace the first number of the dividend in red and trace the divisor. Work the steps for just the red numbers. Next, switch marker colors and do the next problem.

Have you ever tried the box method? I saw this on Instagram and shared with my math teammate. I know that several of her strugglers were able to grasp this method better than the traditional way to do long division.

I'm always looking for new ways to teach math. Box method is a keeper. Thanks!

Wow! I love the box method. I think they should’ve always taught it this way. It seems so much easier.
