"Multiplication with 0 in the middle or at the end of the factors" Multiplying three-digit numbers with two-digit numbers PPT

Part One: Exciting Introduction

Oral arithmetic:

40×12= 140×7= 28×3=

20×700= 13×6= 203×2=

18×3= 250×3= 107×5=

Multiplication PPT with 0 in the middle or at the end of the factors, part 2: knowledge explanation

There is 0 at the end and added at the end

160×30= 16×300=

Summary: First multiply the numbers before 0, then see how many 0s there are at the end of the factors, and add a few 0s at the end of the product.

106×30= 4800

Give it a try.

Don't miss the 0 in the middle

450×20=9000

1. To calculate 450 × 20, you can first calculate ( ) × ( ), then add ( ) zeros at the end of the multiplied number 90, and the final number is ( ).

2. There is a 0 at the end of one factor, a 0 at the end of the other factor, and there are at least ( ) 0s at the end of the product.

Judgment (mark “√” if correct, “×” if incorrect)

(1) When calculating 85×106, the step of multiplying the tens digit by 8 and the tens digit by 0 can be omitted. ( )

(2) When calculating 225×16, there is no 0 at the end of the product. ( )

(3) 650×40＝2600 ( )
