After doing this activity, N can now do simple additions mentally. I have to stop here and say, Montessori methods of teaching Maths is awesome! So clear to understand!
Anyway, i digress. I continue with more additions with N. I prepared some addition cards. This time i taught him that 10 plus 10 equals 20, 20 plus 10 equals 30 etc.
Prerequisite: Child must know how to count in tens.
I wrote the sums on blue cards. Somehow N got ahead of me, took the cards out and tried working on them (without the visual aids). He first took out the '10 +10' card, and read aloud the sum. But looked at me for answer, to which i reluctantly replied '20'. He continued on with the '20 + 10' card and to my surprised, he declared '30 as the answer! I watched on as he continued with '30 +10', '40+10', etc and gave all the correct answers effortlessly. There goes my lesson plan.
Still, i got him to work on the cards again with the ten beads this time. I wanted to make sure he understood the concept and wasn't merely memorizing the answers.
Next i worked on his number recognition in Mandarin. I wrote numbers from 10 to 90 on yellow cards, and the same numbers but in mandarin in pink cards.
N had to match the two cards.
