... Our school (a middling-rated public California school) starts bar charts in kindergarten, so I would expect 5th graders to be able to do them in their sleep. Basic charting/graphing is part of the California state standard for kindergarten, so it should be taught in *every* California kindergarten regardless of the school's ratings. I'm reasonably certain that my 6yo would be able to comprehend the basic concepts behind a pie chart, although he probably could not articulate them. -- Be well, Barbara (Julian [6], Aurora [4], and Vernon's [19mo] mom) This week's special at the English Language Butcher Shop: "Together we help the future grow." -- School slogan |

Not until my son learned it (and I have a math degree, fwiw) I learned about stem-and-leaf plots about 1985 from Edward Tufte's beautiful book "The Visual Display of Quantitative Information". I did NOT get stem-and-leaf plots in school or college, but I was in theoretical math and computer science, neither of which are very concerned with the display of data. My degree was theoretical ("pure") math and CS as well. But I did have 2 (required) semesters of probability and statistics --Robyn I did math undergrad and like you didn't learn about stem-and-leaf plots. Instead I ran into the stem-and-leaf plots as a grad student in city planning where we had to learn statistics. BTW, I don't think of these plots as useful for young children to learn. Jeanne |

POLL: Math questions regarding upper elementary school (xpost to m.k.)
Tennessee tests the stem and leaf plot in 6th grade. (All of one question
last year-so it's not a major topic by any means). It is first introduced in the grade 4 book (University of Chicago Everyday Math), and revisited after that. Everyday math, like Connected Math, is a spiral curriculum, with the idea being that children don't necessarily master things the first time they do them. I think it's crazy, but that's a topic for another thread. Our gifted math students work by acceleration, so it is possible that a gifted student would be introduced to this earlier. Students with disabilities in math usually end up with the curriculum pared down to the essentials, so I expect the step and leaf plot wouldn't be covered. I don't know if they actually learn it or can explain it or not. I don't recall seeing one until college-and when I saw it, had no trouble understanding it. I expect I could explain and teach it without trouble-but am just as glad I don't have to, since it seems irrelevant for a 4th grader. |

I'd never heard of stem and leaf plots before - chi squared distributions, but not stem and leaf plots. -- Penny Gaines |

But I'm only interested in 4th grade math. For things the kids will be tested/evaluated on in 6th, introducing it in 4th doesn't seem unusual or unreasonable, within the semi-accepted paradigm of teaching to the test. I think you already know my opinions on that! I'm finding the responses VERY interesting and (tee hee) totally backing up my hypothesis. I wish more people would respond though. I really need enough data to cover at least 50% of all states to fight this battle in court. I doubt my responses are necessarily representative of my entire state, and mine's a small state. AFAIK, the curriculum used at our public schools was chosen by the local school board, not mandated by the state. Of course, the testing is state-based. I don't know if stem-and-leaf charts show up here in the 4th grade test or not until 6th, but I could find out if you want. I'd guess some states are more consistent on public school curricula than others. I'll be interested to hear what kind of court battle you could be having over stem-and-leaf charts once you have enough data to reveal your reasons for asking. ;-) --Robyn |
