Сызықтық функциялар графиктерінің өзара орналасуы

Сабақтың мақсаты:                                                                                                                                                              1. Функция туралы ұғымдарын дамытып, сондай-ақ олардың графиктері мен қасиеттерін қайталай отырып, алған білімдерін одан әрі тиянақтау.                                                                                                                2. Тақырып бойынша, білімді одан әрі кеңейту, теориялық білімді практикамен ұштастыруды қалыптастыруын дамыту.                                                                                                                                                                          3. Топпен жұмыс жасауға, өзін, өзгені бағалай білуге, орындалған тапсырмаға сыный көзқараспен қарауға, ұқыптылыққа үйренуге тәрбиелеу.                                                                                                              Сабақтың түрі: қайталау сабағы                                                                                                                 Сабақтың әдісі: сұрақ-жауап                                                                                                                           Сабақтың ңөрнекілігі: плакат, реферат                                                                                                                                                               Сабақтың барысы:                                                                                                                                                        І Ұйымдастыру кезеңі                                                                                                                                                    ІІ Мұғалімнің кіріспе сөзі                                                                                                                                                  ІІІ Үй тапсырмасын тексеру                                                                                                                                                         ІV Бекіту                                                                                                                                                                           V Қорытындылау                                                                                                                                                             VI Үй тапсырмасы                                                                                                                                                                                           VII Бағалау                                                                                                                                                                                              І топ: Сызықтық функция, олардың қиылысуы.                                                                                                                                                 Ауызша:                                                                                                                                                                              1-оқушы.
