Counting with the Abax

Well, it took us a while to get back to this, but we did more lessons today – Lessons 1 and 2 in Counting with the Abax. WOW. This is really cool. We mostly worked on adding two three-digit numbers, and it’s a lot easier (I think) than adding them in columns. You don’t have to ever add up things in your head. It’s all based on knowing the complements of ten. We did also do some work on “traditional” addition, since we double-checked all our abax calculations by working them out the regular way. It’s funny, because just looking at the counting board, I really had no idea how this was going to work, but after going through the lesson it’s really simple and obvious. I’m looking forward to doing more, and this time it won’t take us a month before we do the next lesson. :D
