This evening was the first session for EDU Elementary Mathematics. It's about how children learn Mathematics. There were 3 lessons on problem solving. Lesson 2 was about using a person's name to solve a Mathematical problem. The activity is in about which letter is counted 99th in a name. I chose this activity for my reflection as I find it very interesting and engaging to use a personal name as an activity to solve mathematical problem.
I use my own name to find which letter is counted 99th. I count and write down the numbers in sets counting from left to right, then right to left for the next set till I reached 99. As I was counting the sets half way through, I observed there was a pattern of numbers. From the first letter of my name, I just need to add 14 to alternate set till I reach 99. Upon realisation this pattern and reaching the number 99, the feeling was like the 'light bulb' in my mind lighted up and “ah.ha.. moment. Wow! “
What have I learnt for this first session?
- Concrete - counting the numbers
- Pictorial - writing the numerals in a row
- Abstract - seeing the pattern of 14 per alternate set in the mind.
