I'm not really sure if I can say that multiplication itself was a challenge, but actually getting through the lessons was the challenge. The kids, especially H, really started to slow down as the problems got larger. Not because they couldn't do them, but because they "didn't want to" do them. Oh the drudgery....
But with some arm twisting, and some cheer leading, and maybe even a little bribery, all lessons have been completed successfully. What a relief!
I will be waiting a few weeks before diving into the next level (division) so that the kids can decompress a bit. I've decided a nice change of pace is what they really need, so the next month or so will be primarily focused on science, maybe some history, more reading and writing.
This is what I love about HSing. The flexibility to make changes as we go. It makes learning so much more fun when you aren't chained to a desk, enduring the same monotony day after day - and it makes teaching so much more satisfying as well. Oh, and best of all - I get to spend time with my kids. ;-)
