There are some great , that we've used for smaller numbers, up to 3 digits long. How many can you remember?
Find 769\div3 by doing the following:
Find 600\div 3.
Using the fact that 769=600+150+18+1, complete the statement with the missing numbers:
3 goes into seven hundred sixty nine ⬚ times with a remainder of ⬚.
Dividing by one number can often help us when we need to divide by a different number, as we see here.
Find the value of 40\div4.
Dividing by other digits means we can use things like partitioning or the area model to help us.
Let's use an area model to find the answer to 133\div 7.
We set up the area model using a rectangle like this:
Now if we don't know straight away what 133\div 7 is, we start with something we do know, like groups of 10.
Find the area used so far if we take out 10 groups of 7.
How much area is remaining?
What is the width of the second rectangle?
Using the area model above, what is 133\div7?
