Addition

Tips for Parents

There are many different ways to add one number to another. In St. Cronans BNS, all classes are taught to add in the same way, using the same words and phrases. This helps the boys understand addition and it avoids confusion.

When you are helping your son with his addition homework, it is important to:-

  • Use the words and phrases as used in class
  • Work out the addition sum the same way as it is done in class


This will help your son understand what he has learnt in school.

Remember this might be different from what you learnt in school!

These are the words we use:-




This is how we say our Addition Tables

"2 and 2 is 4"
"3
and 2 is 5"...

"9
and 5 is 14"
"10
and 5 is 15"...

"7
and 3 is 10"
"8
and 3 is 11"...


Check if your son knows his Addition Tables by asking:-

"6 and 4 is?"
"10 and 2 is?"....

Make sure to mix up the order you ask the tables in, to be sure your son really does know them.


This is how we read an Addition Sum



Read from
Left to Right

Say
"3 plus 4 is 7" or
you can say
"3 plus 4 equals 7"



This is how we work on Addition Sums


To make this sum easier to work on, we rewrite it as


When writing down a sum, remember to put
a
U over the Units (1s)
a
T over the Tens (10s) and for big sums
a
H over the Hundreds (100s)

Click on the sum to see how it is done.


This is how you work out this sum

Step 1. Start at the top unit, 3 plus 9 equals 12
Step 2. I have to rename 12 to 1 ten and 2 units. I write down 2 under the units and carry the "ten" to the ten side.
Step 3. Start at the top ten, 4 plus 2 is 6, 6 plus 1 equals 7.

My answer is 72
