Division 3 6 Now to carry on with Dividing whole numbers using place value begins with 3.6 x10= 360 multiplication using place value. writing the dividend in place value format. In expanded This could also be done Or in table ormat: notation: in word format: Hundreds Tens Ones A USING PLACE VALUE TO 800+60+3 8 hundreds + 6 tens + 3 ones 8 6 3 ADD, SUBTRACT, ~ULTIPLY, + 200 +40+9 + 2 hundreds +4 tens +9 ones 2 4 9 1000+100+12 10 hundreds + 10 tens + 12 ones 10 10 12 AND DIVIDE WITH U/HOLE NUMBERS The final answer is 1000 + 100 + 12 = 1000 + 100 + 10 +2=1112. Using a table helps visualize this, where the numbers - 80 + 9 greater than the number below. in place value format are written on the perimeter of the table 600 + (20- 80 + (7-9) Working with negative numbers (my students need this set-up).
