Division is related to multiplication, so helps us when we need to solve division problems.
Find 6178 \times 4.
Let's see how we can use area models and arrays to work out division problems, numbers up to hundreds.
Let's use an area model to find the answer to 45 \div 3.
We set up the area model using a rectangle like this:
We don't know what 45\div3 is straight away, we start with something we do know, like 30\div 3.
Find the area used so far if we take out 10 groups of 3.
How much area is remaining?
What is the width of the second rectangle?
Using the area model above, what is 45\div3?
We can use what we know about place value and partitioning numbers to solve division problems as well, as we see in this video.
Find the value of 396 \div 3.
We can use a vertical algorithm to solve division, and it helps when we work with larger numbers, as this video shows.
Find the value of 856 \div 8.
