It was interesting to listen, understand, and solve the duplexes of 1, 2, 3, 4, and 5 digit numbers and finding squares of 1, 2, 3, 4 digit numbers. And it takes practice to really get a hang of straight division of dividing a no. with 2 and 3 digit nos. and +ve and – ve flag figures. It is inspiring to see the use of bar figures in division to make the process easier. The examples to show variations in which there was a 7 digit no ( dividend) and a 6 digit divisor seemed complicated at first but after couple of tries, I was glad to understand it fully. The proportionately section was captivating. There is so much to do and play with numbers.
I am so impressed that Mallika is able to work on the triples.
