I am sure that you must have learnt addition by now. I am going to train you for a smarter addition skill. The aim is to make addition ‘simple & visual’ for you.
Let’s take a look at an example
8 + 4 & 10 + 2
The answer is same in both cases but somehow calculating 10 + 2 is faster & easier. Isn’t it ?
That’s the trick!
We need to ‘target 10’ (or 100 & 1000 for higher levels) to make our addition smarter.
For mastering this “target 10” skill, I need you to know all the number bonds of 10 at your finger tips. I am noting down a few ‘number bonds of 10’ for you :
1 + 9 = 10
2 + 8 = 10
3 + 7 = 10
…
…
…
Please complete this list in your notebook. You can master these number bonds using these games as well –
Number Bond Game 1 (no login/password needed for the game)
Number Bond Game 2 (no login/password needed for the game)
Once you are super-confident with the number bonds of 10, try to use this skill in addition.
I am solving one question from each worksheet for you. Please refer to it and let me know incase you have any further question.
Here you go :
7 + 4 (break 4 into 3 & 1, because 7 needs 3 to make 10)
= 7 + 3 + 1
= 10 + 1
= 11
76 + 9 (break 9 into 4 & 5, because 6 needs 4 to make 10)
= 76 + 4 + 5
= 80 + 5
= 85
Once you complete these worksheets, you will surely be smarter at your addition work.
Enjoy smarter addition!
Nice concept
