[quote=Anonymous][quote=Anonymous] They don't know what they are doing. They tried to teach ALGEBRA to my 4th grader. Figure out what x is: 420-x=400. My kid was confused so I asked the teacher to clarify how she was teaching this so I wouldn't confuse my kid further with a different approach. I asked, "Are you teaching them to isolate x on one side of the equation?" Answer: "No, they are not ready for that yet. We are just teaching them to memorize that they should subtract the smaller number from the larger." They teach it like it's a game with arbitrary rules. Ridiculous.[/quote] Singapore Math has this kind of problem for first-graders. (With smaller numbers, obviously.) And my 5-year-old was able to understand it. If that was the teacher's explanation, then yes, that explanation is ridiculous. But expecting a fourth grader to be able to understand that if 420 minus some number is 400, then that number is 20 -- that's not ridiculous. [/quote]
