**Long Division & MathLine**

____ 6)192 First Problem:

2
**For traditional Long Division,**

teach the algorithm: 1) Divide or D 2) Multiply or M 3) Subtract or S 4) Check or 5) Bring Down or BD

3
**____ 6)192 Take the problem Long Division Divide = D Multiply = M**

Subtract = S Check = Bring Down = BD Take the problem ____ 6)192 3

4
**____ 6)192 6 into 1? Long Division Divide = D Multiply = M**

Subtract = S Check = Bring Down = BD 6 into 1? ____ 6)192 4

5
**____ 6)192 Put 1 on MathLine Long Division Divide = D Multiply = M**

Subtract = S Check = Bring Down = BD Put 1 on MathLine ____ 6)192 5

6
**____ 6)192 6 into 1? No Long Division Divide = D Multiply = M**

7
**____ 6)192 6 into 19? Long Division Divide = D Multiply = M**

Subtract = S Check = Bring Down = BD 6 into 19? ____ 6)192 7

8
**____ 6)192 Put 19 on MathLine Long Division Divide = D Multiply = M**

9
**For long division on MathLine start dividing from the left**

Divide = D Multiply = M Subtract = S Check = Bring Down = BD For long division on MathLine ALWAYS start dividing from the left

10
**____ 6)192 6 into 19? One Group of 6 Yes, how many times?**

15
**multiply the remainder**

Long Division Divide = D Multiply = M Subtract = S Check = Bring Down = BD Make sure the students do not multiply the remainder back in! Only multiply 3 X 6, or 3 groups of 6 15 15

16
**____ 3 6)192 Multiply 3 x 6 Long Division 3 Groups of 6 Divide = D**

Multiply = M Subtract = S Check = Bring Down = BD 3 Multiply 3 x 6 ____ 6)192 3 Groups of 6 16 16

17
**____ 3 6)192 Multiply 3 x 6 Long Division 3 Groups of 6 Divide = D**

Multiply = M Subtract = S Check = Bring Down = BD 3 Multiply 3 x 6 ____ 6)192 3 Groups of 6 17 17

18
**3 _ ___ 6)192 18 We multiply 3 x 6 and get 18, so we put**
