Objective: To understand long division.
13
Long Division Long Division is a special method for dividing larger numbers.
14
Long Division Long Division is a special method for dividing larger numbers. Long Division has four steps; Dividing, Multiplying, Subtracting, Bring down. Does McDonalds Sell Burgers?
15
Long Division What is 664 ÷ 2 = ? Dividend Divisor
16
Long Division What is 664 ÷ 2 = ? Before we begin, lets look at what we are asking. We are asking how many 2’s you subtract from 664 to get to zero. 664-2-2-2-2-2-2……….. = 0
17
Long Division What is 664 ÷ 2 = ? Remember – division is just a short hand version of subtraction.
18
Long Division What is 664 ÷ 2 = ? First need to rewrite the problem using the division bracket. 664 ÷ 2 = 2) 664 The divisor goes on the outside.
19
Long Division What is 664 ÷ 2 = ? Step 1 - Dividing 2) 664 How many times does 2 go into 6? Or another way to look at it is 2 x ? = 6.
20
Long Division What is 664 ÷ 2 = ? Step 1 - Dividing 2) 664 How many times does 2 go into 6? Or another way to look at it is 2 x ? = 6. 1 x 2 2 2 x 2 4 2 x 3 6 2 x 4 8
21
Long Division What is 664 ÷ 2 = ?Step 2 - ? 3 2) 664 1 x 2 2 2 x 2 4 2 x 3 6 2 x 4 8
22
Long Division What is 664 ÷ 2 = ? Step 2 - Multiplying 3 2) 664 3 x 2 = ? 1 x 2 2 2 x 2 4 2 x 3 6 2 x 4 8
23
Long Division What is 664 ÷ 2 = ? Step 3 - ? 3 2) 664 6 1 x 2 2 2 x 2 4 2 x 3 6 2 x 4 8
24
Long Division What is 664 ÷ 2 = ? Step 3 - Subtracting 3 2) 664 -6 0 1 x 2 2 2 x 2 4 2 x 3 6 2 x 4 8
25
