Ndugu Mzazi / Mlezi wa mwanafunzi wa Baobab,
Uongozi wa shule ya Sekondari Baobab umeandaa orodha ya mazoezi (assignments) kwa wanafunzi wa kidato cha tatu ambayo yatakuwa yakiwekwa hapa kwenye tovuti hii.Tunakuomba uyapakue (download),kisha uyachapishe (print) na umpatie mwanao ili afanye kama sehemu ya kazi yake ya nyumbani (Home Package) kwa mujibu wa ratiba inavyoonyesha.
Tunasisitiza kuwa mazoezi yote kwa kila somo yafanyike kwenye daftari la mazoezi la somo husika. Baada ya mwanao kufanya mazoezi hayo scan kazi hiyo au upige picha kurasa zenye majibu yake na ututumie kwa njia ya e-mail ya kidato cha tatu
Lengo la kutuma kwa email ni ili walimu wake wasahihishe na kutoa mrejesho kwa njia hiyo hiyo. Ratiba ya wanafunzi kufanya mazoezi na kurudisha majibu kwetu kwa e-mail imeambatanishwa hapa chini.
N.B: Madaftari yote ya mazoezi kwa kila somo yatakusanywa siku ya kufungua shule na wanafunzi watafanya Mtihani ambao maswali yatatoka miongoni mwa “assignments” alizopewa wiki ya kwanza ya kufungua shule.
UTARATIBU WA KUKUSANYA KAZI.
Kazi zote zisichanganywe, kila somo likusanywe kwa “attachment” ya peke yake ili kuondoa mwingiliano wa kazi. Shule inakushauri mzazi kupakua app ya scanner kwa wanaotumia simu janja (smart phone) ili kurahisisha ukusanyaji mzuri wa kazi.
ZINGATIA: Tunakuomba mzazi/mlezi umsimamie mwanao afanye kazi kwa wakati na kuzituma kama inavyoelekezwa kwenye ratiba. Mazoezi mapya yatakuwa yakitolewa kila Alhamisi ya kila wiki.
Kwa msaada zaidi wasiliana na walimu wa Taaluma: 0754 611 538 / 0768 611 538 / 0763 367 567 na 0768 628 925
Asanteni kwa Ushirikiano wenu.
