Division is splitting into equal parts or groups.
For example if there are 12 chocolates, and 3 friends want to share them, how do they divide the chocolates? The answer would be 12 divided by 3 is 4: they get 4 each.
As a class we talked about how division is the opposite to multiplication. Therefore if we know the multiplication fact we can solve the division problem.
Why? Think of the numbers in rows and columns like in this illustration:
3 groups of 5 make 15… so… 15 divided by 3 is 5
For Example: There are 7 flowers to share with 2 girls.
But 7 cannot be divided exactly into 2 groups,
so each girl gets 3 flowers,
but there will be 1 left over:
We can then check by multiplying
If we look at it “the other way around” we can check our answer:
2 x 3 + 1 = 7
2 groups of 3 plus 1 equals 7.
We practiced this skill with some larger numbers and using the short division method.
Here is a video to remind everyone on how we solved these division problems using larger numbers
There is another strategy using long division which we didn’t use during class time but is still a good strategy to use if you prefer it. Check out this video to see more…
