- Interesting. This sort of relates to how I originally taught the concept of
- "multiplication". I came up with all sorts of different types of problems
- and asked the children to write "multiplication sentences" that would tell
- us how to find the answer. For example, "Five cars go to the tire store one
- afternoon. Each car needs four new tires. How many tires does the tire
- store sell that afternoon?". The answer, of course, being "4*5". I also
- drew squares and rectangles, four cans of beans with thirty beans in each
- can, etc. I don't know how much of this the kids "got". But so it goes.
-
- Moving onward, I didn't spend a whole lot of time drilling the
- multiplication tables. That didn't work with me, and I doubt it would work
- with most of my students. Instead, I put the chart on the wall, and plunged
- right into doing multi-digit multiplication problems. I'm hoping that
- they'll eventually get it down to the point where they no longer have to
- look at the chart on the wall.
-
- However, I readily admit that I am just learning how to teach math. I am by
- no means a master teacher. I know what direction I want to move in, but I'm
- definitely still learning how to get there.

- The math book spent a whole 9 lessons on drilling basic multiplication
- facts. *I* was bored just LOOKING at that. I refused to do it. I knew from
- my own background that it was possible to memorize most of those things
- with little tricks and from just plain using them, so I'm primarily
- providing a ton of application problems, mainly set problems and geometric
- problems since one of my kids has serious language difficulties, two have
- problems reading, and one of the kids with reading problems also has some
- language problems.

- I just wish that I had the *TIME* to dive into conceptual math.
- Unfortunately, the materials the school board provides me aren't up to that
- sort of task, and I'm already working 10-hour days just providing a basic
- by-the-book education so I'm not going to develop my own materials. Do you
- know of any good kits or other such materials which would be useful? If so,
- I'll order them for next year out of my supplies budget (I cannot, alas,
- get it for this year -- my predecessor already spent all of my classroom's
- funds for this year).
