The Joy of Long Division

The first step to teaching the boys long division was to teach myself long division.

I'm sure I did it at school at some point but that was at least a decade (*cough* or two) ago and it turns out that's it definitely nothing like riding a bike.

Step 1a : Google the topic and print out step by step instructions
Step 1b : Print out drill sheets and sit at the kitchen table with a garibaldi and a coffee
Step 1c : Check facebook a few times and empty the dishwasher
Step 1d : Do about 4 sums before declaring the invention of the calculator the best thing since sliced bread

Step 2 : Teach the boys long division

Here's a neat little trick to help them remember the steps :

Daddy Division
Mummy Multiplication
Sister Subtract (or in our case Stevie the cat Subtract)
Brother Bring down (if we've had an argument with our brother, we can substitute Bailey the dog)

So for example:



Then repeat, by saying Daddy divides 29 by 3 and writes the answer on the line .. and so on.

As soon as there's nothing for Brother (or Bailey) to bring down, whatever we're left with is the remainder.
