Remember "My Favourite Number" game? So here we ask our children, what number do we need from 7 to make 10? Which they will unanimously answer 3!
So we do 3 + 7 first, and the answer is, my favourite number, 10!
Next we ask, "So if we borrow 3 from 6 just now, how much is there left from 6?"
Just like that we have changed 6 + 7 into something much much simpler; 3 + 10, which is just 13!
Ok the image looks complicated, but it is much easier than it seems. 😎
Next, I will go through a few more examples, this time the students will "guide and teach" me.
Once they know they trick, we move on to....
Suggested activity for Stage 3 - Timed Practice
quick quick quick!
To master addition, we challenge our children to complete a set of questions within a short amount of time!
I will prepare simple rewards like sweets or longer break for those who can beat the time and get all the questions correct.
But before we do so, we need to have some questions ready for them. Don't worry if you can't come up with the questions. I have found a great tool for you! Click on this link
Here's an example of a worksheet created!
There are 25 questions here. So I usually give the students 2 mins to complete all the questions. Then the next week, I reduce the time to 1 min 30 seconds, and finally 1 minute.
That's roughly 2 sec per question in the end, which means they must use mental calculation in order to complete this!
After your child has mastered this exercise, ask him/her how do they feel now that they have become so much stronger in maths! 💪
This feel-good moment will stay with them a long time and further inspire them to conquer other difficulties in life!
At the same time, don't forget to give yourself a pat on the back for providing guidance and showing patience! 😁
Here's the best part: Sometimes during normal class, when a student goes back to finger counting out of habit, I will remind them about my favourite number! The student automatically remembers to add using this method!
