desertflower Posted December 28, 2015 Share Posted December 28, 2015 I don't know anything about a Japanese abacus. But I'm using the mental math pages in the back of the Singapore Math Home Instructor's Guide. Quote Link to comment Share on other sites More sharing options...
forty-two Posted December 28, 2015 Share Posted December 28, 2015 I've been using the Abacus Adventure app ($1.99, and there's also a free trial version): https://itunes.apple.com/us/app/abacus-adventure-1/id568745401?mt=8 The instruction's not quite sufficient if you have no idea how to use an abacus (I have a basic idea and it helps me expand on the instruction for dd9), but the progression is pretty good and you can repeat levels (with different problems) as many times as you want. Whenever dd9 gets stuck, we go back several levels. Usually when we get back to the difficult level it's not so difficult anymore :). One note: if you try out the free version and like it, when you buy the paid version you have to start over from the beginning. 1 Quote Link to comment Share on other sites More sharing options...
Malory Posted December 29, 2015 Share Posted December 29, 2015 Learning the Japanese abacus is like learning a musical instrument in some ways. You need to practice it everyday for a length of time before you can benefit from it mentally. My children can do mental calculations of big numbers quite easily now, after a few years of learning it. It is best if you can find an instructor to get you started. 1 Quote Link to comment Share on other sites More sharing options...
Rosie_0801 Posted December 29, 2015 Share Posted December 29, 2015 We use board games. Hours and hours of board games. I'm immensely grateful that my brother has the stamina for it. I can't cope. :laugh: Quote Link to comment Share on other sites More sharing options...

Then we will see. Hopefully someone will suggest anything else :) Edited December 29, 2015 by rushhush08 Quote Link to comment Share on other sites More sharing options...
