Short Division

LI: To understand how to use algorithm to solve complex division equations.

For maths, we have been focusing on using an algorithmic strategy to solve advanced maths problems regarding division. These strategies are called long division and short division. I prefer to use short division because it is more efficient. Some examples of equations we solved with this strategy is 476 ÷ 7 or 823 ÷ 4.

To use short division for an equation such as 217 ÷ 5. First, we see how many times 5 can fit into 2, however this is unable to happen so we expand the number to 21 which includes the 2nd digit of the number. 5 fits into 20 four times, with 1 remaining. You put 4 above the 2nd place value column and you place a small number beside the following digit. That number then becomes 17, so we see how many times 5 can fit into 17. This is able to happen 3 times, with remainder 2. Write how many times 5 can fit into that number and the answer to 217 ÷ 5 becomes 43 remainder 2.

I really enjoyed this maths lesson because I had fun solving hard equations using this strategy and I found it easy because I got used to the thought of using these strategies.
