By teaching my boy on my own, I can work on his weakness and often I will need to think creatively on how to teach him, especially Math.
One of the crazy methods I have thought him is Number Bonds when he was Primary 1.
Now as he is
learning 2 to 3 digits, question like this: 92 = __ + 15, he will follow
my method and it works on him most of time (there are times when he gets answer wrong due to carelessness)
However, beginning of this year, I realise he has problems doing more complex question like:
1. __ more than 85 is 99
2. 100 is 12 less than __
Most of the time, when he sees "more", he will add. But for question #1, it is supposed to subtract, for question #2, it is supposed to add.
So how to teach him to do such questions?
I thought of the method which I have taught my daughter when she was in P2. Before we can conclude which number to add or subtract, we must write out the number sentence first.
My formula for such question is "Dad Love Mum Equal Family". He must follow the steps in sequence when writing out the number sentence.
Step 1: Dad sounds like "Than", the number beside "than" should be placed first. If it is a blank in the question, just draw a square box or underline.
#1 85
#2 __
Step 2: For the word Love, if you see "more" put the + sign, or - sign for the word "less"
#1 85 +
#2 __ -
Step 3: As for mum, look for the number beside more/less. If it is a blank in the question, just draw a square box or underline.
#1 85 + __
#2 __ - 12
Step 4: "is" represent equal
#1 85 + __ =
#2 __ - 12 =
Step 5: For family, it is quite tricky. Like question #2, it could be 100 or 12. But look, you have written 12 for mum (in Step 4), so left 100 for the family.
In the end, the number sentence for #1 & #2 will look like this
#1 85 + __ = 99
#2 __ - 12 = 100
Afterwhich he will continue the number bond method which I have taught him. It could look like a long method for him, but after having several practices, he can easily do such questions.
Wow, I must really credit myself for thinking such crazy method. HA!
My daughter, who had Math paper yesterday, told me that she had used this method yesterday. Though my formula "Dad Love Mum Equal Family" may sound crazy to some parents, glad that it works on my kids!
