We are creating generations of people who are totally lost if the battery does in their cell phone. My job keeps me math practiced. You are totally correct about basic math mechanics. When my son was young and learning adding, subtracting positives and negatives, I asked him if the he ever was shown a number line. Nope, never. So, I drew one, he got the concept of negatives and positives right away. When I grew up, everyone knew what a number line was, and understood it. They need to put that back in the early math courses. |

(anyone younger than 45 or so). In 1971 my Bomar "4 banger" cost about $100. A few years later you could get one free with a "fill up" at a gas station. Number lines were on the walls of all the middle school math teachers when I was teaching. I can't imagine a decent teacher not having one when introducing kids to negative numbers.

My daughter now has 2 of the 3 of her kids home schooled. This is not the Jesus thing, it is a program run by the school board and most of it is online. Kids need good grades to do it tho. It all came up over that long division thing. I am sure this will set Harry's hair on fire but it is not a new thing,. Maryland was doing it in the 80s. Back in my public school days, there were several private schools in the area that catered to kids who couldn't make it for whatever reason in the public schools. I'm not saying those kids were "slow." There also was one Catholic high school that got the cream of the crop of bright Catholic kids. I haven't kept up with what is happening in K-12 these days, although I am very impressed with my grandson's progress in his schools. We have a family member who home schools the kids for "religious" reasons. I wouldn't want to be those kids. |

We have a family member who home schools the kids for "religious" reasons. I wouldn't want to be those kids. This is the public school curriculum taught at home. The kids have to be a B or above to even do it. Some people may want a religious tilt but that is not the case with my daughters. The oldest wants to test into a special "arts" school and she won't get all she needs from the public school. (it started with that "division" thing) The youngest is somewhat ADD and they would just want to drug him into submission. He is smart but easily bored. The middle kid may get bumped up 2 grades next year. She is already taking 5th grade math and science. (in the 3d grade) Our home schooling family member doesn't want his precious progeny to mix with kids who don't believe in the same sort of backass christianity he does or, worse, don't believe in jesus at all. |
