I believe seeing number as quantities helps understand maths better.
I try to practice visual perception of maths with my two boys who are of primary school age.
I have used small objects like pasta, popcorn kernels to help them understand and visualise multiplication table.
This app helps visualisation of multiplication table in terms of lots of the number(in-quantities).
$ git clone https://github.com/sunuwars/multiplication-table-fun.git
$ cd multiplication-table-fun
$ npm i
$ npm start
The webapp should now be running on
