How to play : Write down your name on a piece of paper (space them out if you want). Find out what letter would it be at the 99th counting position (do not count the same letter that you last stopped).
- This activity was a tedious yet interesting one. It was amazing to note and discover several possible methods while I was doing the above activity in class. The first one was of course the most obvious, which was to count manually till 99 (no, of course I didn’t do that! I was too impatient to even consider this method…hehehe).
- The second method was the one that I attempted to shortcut the process, which was the placement of numbers and digits with a ‘1’ in them such as 1, 11, 21, 31, etc. These are all in the same column in their respective rows. Hence, when I reached 91, it was easy for me to move on to 99 and voila! I discovered the second letter ‘e’ from the left of my name as the letter in the 99th counting position.
- There were two other methods that my classmates figured out such as all numbers with digit 9 in the ones place are all in the same column (9, 19, 29, 39, etc), as well as numbers that are multiples of 10 are all under the first letter ‘e’ of my name. Amazing, right??
Mathematically, I can't figure out the reason. However, LOGICALLY I may be able to reason it out. *winks* If we were to look at the arrangement of cards from the right, let us spell 'one'. O-n-e. And the number card positioned after we end the spelling is the number '1'. With that, we can chuck the '1' aside and continue to spell 'two'. T-w-o. And the number card positioned after we end the spelling is the number '2'.
Anyone of you out there game enough to try this out?
- There are procedures BUT there are no rote procedures
- 0 to 9 are digits (single); but numbers are all figures and numerals (two digits) such as 43, 76, etc. As teachers, be clear of the terms ‘digits’ and ‘numbers’ when teaching Numeracy to children
Till we meet again in my next blog entry! Very soon, I'm pretty sure! Toodles!
