Mnemonic Device for Long Division
How do I do long division?
Long Division is one of those basic concepts that always seems for some students to be a difficult concept to master. This is a basic mnemonic device ( a way to remember) the steps to long division.
Does McDonalds Serve Burgers?
This is just one of the few mnemonic devices that I use to teach long division.
Does = Divide
McDonalds = Multiply
Serve = Subtract
Burgers = Bring Down
Let's look at the problem to the right to see how this works.
The first step is to DIVIDE. What is 2 ÷ 2 = 1. 1 goes on top of the problem.
Second step MULTIPLY. 1 x 2 = 2. 2 goes below the dividend.
Third step SUBTRACT. 2 - 2 = 0.
Final step BRING DOWN. Bring down the next number which is a 4.
Repeat Does McDonalds Serve Burgers Steps
We are going to continue to repeat the steps until the problem is done.
We just brought down the 4 so now we need to Divide. 4÷2 = 2. 2 goes in the quotient on top.
We multiply the digit we just placed in the quotient 2 by the divisor 2. 2 × 2= 4.
We place the product below to create a subtraction problem. 4 - 4 = 0
Bring Down the next digit 6.
Repeat the steps again to finish the problem.
