I recently discovered anki, it is essentially a flash card program but much better. It has decks of cards already pre-loaded so you can start your child off on times tables right away. Or make your own specialized cards/decks.

It is set up so that you can use it on your phone or mobile device.

It is free.

It syncs both directions so you can practice on your computer, phone, tablet whatever.

You can make your own flashcards with voice/pronunciation and pictures also if you like.

It asks you both directions so that you not only practice knowing what something means, but also recalling it.

SRS stands for spaced Repetition System. It is scientifically set up to ask you and re ask you the questions or meanings at longer and longer intervals just before you might forget– helping you get the info into your long-term memory. You can do this yourself using the game schedule in the book cited below, or the computer does it for you with the help of the anki website.

An EXCELLENT help for language learning and anything you learn worth remembering permanently. There are tutorials on youtube.

The website is Ankisrs.net

It is described in detail in the book Fluent Forever by Gabriel Wyner

My son is already doing much better at his times tables in just a few minutes a day and it is a fun game.
I’m being able to use the Sanskrit yoga terms with more confidence.
This is just the system I was looking for to keep from wasting time and studying with confidence! Good luck to you.
