draw a rectangle 34 by 28

Along the length, mark off 10,10,10,4

and along the width mark off 10,10,8

fill in the grid using those marks

I see 6 10by 10 squares ---> 600

I240 see 2 rectangles 4 by 10 ---> 80

I see 3 rectangles 8 by 10 ---> 240

and finally I see a 4 by 8 rectangle --> 32

so 600 + 80 + 240 + 32 = 952

I hope you are learning this for the purpose of understanding multiplication, and are not actually using this method to multiply.
