Ua, hauv txojcai, 2 txawv le caag kev, Thaum pib. Tog twg los kawm kev paub los ntawm cov zauv paub tab (Geogebra ua ib txhais tau tias), Los yog tsuas kawm txog cov programme xwb (Geogebra ua ib phiaj). Tsis tas li, nws yuav kawm tau los ntawm ib txoj kev dawb (Tub ntxhais kawm ntawv sim rau lawv tus kheej) los yog ib txoj kev tswj kom ze (xib fwb qhia – saib/piav/xyaum).

NTA NTA:

Cov me nyuam kawm ntawv siv Geogebra ua ntau yam hauj lwm nrog ib mathematical pib taw tes.
  1. Impetus 2 ntsiab lus nyob rau hauv lub cev ua kom sib haum.
  2. Teev cov khoom (2,3) thiab (5,4.5) ua kom sib haum ntawm lub cev txhais tau tias yog. lub thawv input.
  3. Impetus 2 cov ntsiab lus thiab rename lub 2 ntsiab lus.
  4. Construct ib kab nrog ntev 7.
  5. Tsim ib txoj kab, dua los ntawm cov ntsiab lus A(3,5) thiab B(5,9).
    1. Nyeem cov kev cai rau cov kab.
    2. Nrhiav cov nqes hav siv. cuab tam “nqes hav”. Nyeem cov kev cai rau cov kab.
  6. Muab tej triangle.
  7. Construct ib triangle nrog cov nplooj ntawv lengths 7, 6 thiab 4.
  8. Tsim ib triangle nrog 1 kaum sab xis 30 degrees thiab ib lub kaum sab xis ntawm 34 degrees.
  9. Construct ib triangle nrog qhov siab 4 thiab hauv qab 7.
  10. Tsim ib daim duab peb sab, Qhov siab thiab baseline yuav dynamically hloov;.
  11. Construct ib equilateral triangle.
  12. Construct ib equilateral triangle nrog sab ntev 5.5.
  13. tsim kom muaj 3 triangles nrog baseline rau 4.
  14. Muab tej square.
  15. Teev tej square.
  16. Teev cia ib square nrog nplooj ntawv ntev 5.
  17. Construct ib rectangle nrog tog 6 thiab 4.
  18. Muab tej vajvoog.
  19. Construct ib lub vajvoog uas radius 5.
  20. Construct ib triangle nrog baseline 6 thiab cov txheej txheem ntawm lub baseline rau hauv 4 raws li qhov siab.
  21. tsim kom muaj 2 voj voog. Ib radius rau 3 thiab lwm radius rau 6.
  22. Construct ib triangle nrog inscribed vajvoog (kaum sab xis.).
  23. Construct ib triangle nrog ib lub vajvoog rewritten (Mindtnormal).
  24. Xaiv ib tus chij NO, Thiab sim tsim tus chij nrog cov cuab yeej hauv GeoGebra.

 

KOS TXAWV/TEJ YAM:

Cov me nyuam kawm ntawv siv GeoGebra kos ntau yam, xws li ib lub tsev, ib tug neeg, tsheb los yog lwm yam tsheb. Daim ntawv qhia no qhia txog cov me nyuam kawm ntawv yuav siv cov kev siv.

EXPANDING QHOV KEV UA KOM IB CE MUAJ ZOG NROG LUB TSEV/TEJ YAM

  • Teeb mathematical frames, yuav tsum tau ntsib;. Xws li, tsim ib lub tsev nrog
    • txawv mathematical shapes, xws li Squares, rectangles, vajvoos peb sab, equilateral triangles, ncaj-legged triangles,
    • cov dimensions, thiab lwm yam..

CUSTOMIZING LUB COORDINATE LAWV THIAB XAUV MUS GRID

Troels Iam_fo0o0ode C
Kuv yuav ua hauj lwm ua tus lwm xibfwb ntawm cov xib fwb cov kev kawm nyob rau hauv Jelling, qhov twg kuv qhia nyob rau hauv kev kawm txog zauv. Kuv muaj yav tag los lawm pedagogical cov neeg pab tswv yim hauv kev ua lej thiab German hauv UCL qhov chaw rau cov chaw muab kev pab kev kawm txuj (CFU) Vejle thiab Odense. Kuv kuj muaj ib tug xib fwb nyob rau xyoo 2011 (7.-9. hoob) nyob lyshøjskolen hauv Kolding. Nyias muaj nyias thiab khiav lag luam, inter alia,. cov websites www. lærklokken. com thiab www.iundervisning.dk, ggbkursus.dk. Kuv yog nyob rau hauv favour, tias kev kawm yuav tsum tau nkag puas siv tau thiab kom deb li deb li sai tau dawb xwb.

  3. Nyob zoo, ib tug xib fwb laus.
    Thiab tau zoo siab nrog cov ce muaj zog, Vim geogebra yog hom tshiab rau kuv.
    Nws muaj hmoo uas tseem yog ib yam dab tsi rau algebra?
    Vim hais tias ces kuv yuav tsum lees, kuv paub dab tsi kuv xav tau ib zaug rau..
    Xijpeem, ua tsaug.

    • Nyob zoo Gitte. Tsaug cov lus thiab cov sawv.☺️ dab tsi yog nws, kev siv zauv? Kab zauv kua, txo? Koj yuav tsum siv dab tsi rau koj? Ua Tsaug, Troels.

      • Hej Troels.
        Ob leeg ua tau, Kuv tsuas tsis siv geogebra, Thiab kuv yog belching nrog tej yam yooj yim li muab ib feem.
        Tsaug rau lub teb thiab yeej Merry Christmas!😋
