Division Games........ Before the Worksheets


5's:

Your child should know their 5's (multiplication facts). It is vital that they know these multiplication facts because they will be a huge help in division.

First, practice reading multiplication / division problems and rewrite them into a division problem. So, 3 x 9 = 27 can become 27 / 9 = 3.

There are several strategies for solving any division problems with the divisor of 5:

The best way to explain is to show an example.

Look at: 30/5 .......Here are some ways to solve this problem:

(1). By looking at the divisor you know this is a 5 fact.

(2). I might think of the hands on a clock (clock facts) , how they increase by 5. When the clock is on 4 it is 20 after, so the answer is 4. So 20/5=4

(3). I might simply use the strategy of skip counting by fives. 4 groups of 5=20, so 20/5=4


Crazy Math Mom Tip

You can use a calculator (there is one on your cell phone) to play some division games. Repeated subtraction is division, so I have my children type in a large number that ends in 5 or 0 on the calculator. Next, we see how many 5's we have to subtract to get to 0. Once you subtract one 5 you can simply press the = sign to add another 5, and so on.

FUN FACT:
If you want to know whether a number can be evenly divided by five look at the number's last digit. If the last digit is a zero or a five, then the number is divisible by five. 1,573,740 ends in zero so it is divisible by five. Since 23 ends in three, it isn't divisible by five. This is a cool math trick!

6's

Your child should know their 6's (multiplication facts). It is vital that they know these multiplication facts because they will be a huge help in division.

First practice reading a division problems out loud.

There are several strategies for solving any division problems with the divisor of 6:

The best way to explain is to show an example.

Look at: 54 / 6 .......Here are some ways to solve this problem:

(1). By looking at the divisor you know this is a 6 fact.

(2). I might skip count and realize that I have to skip count 9 times to get to 54.

(3). I might look at the difference between the divisor(factor) and quotient (product) to see how far they are apart. I might start at a 5 fact ( 6x5=30) ..I know it has to be more than 5 so I try 6x8 ( I know the rhyme 6 asked 8 for a date, six times eight is forty eight), I realize that if I add 6 to 48 I will get 54. So the answer is 9. 54/6=9


FUN FACT:
If a number is BOTH divisible by three (see the three rule) AND an even number (ending in 0,2,4, 6 or 8) then it's divisible by six too. 312 is an even number, if you add up all the digits they equal six, which is divisible by three. So, 312 is divisible by six.
