We have learned some different strategies to help us divide numbers, like partitioning or using an area model. Try this problem to help you remember.
Find the value of 40\div4.
To make a division easier, we can divide both numbers by 2.
We can also think of dividing by 4 as dividing by 2 twice.
This video shows how a short division algorithm can be used to solve division problems, with trading, remainder and a zero in the answer. An estimate also helps to check the reasonableness of the answer.
Find the value of 856 \div 8.
When you are dividing, you always start with the digit that is farthest to the left. If you get to a digit that you can't divide into, make sure you put a placeholder zero in the answer, before moving to the next digit.
