Mavzu: 5-SINF KURSINI TAKRORLASH
Darsning maqsadi:

1. 
   Ta’limiy maqsad: O’quvchilarga mustaqillik haqida, ularni Vatanparvarlik ruhida tarbiyalashga oid tushunchalar berish. 5-sinfda o’tilgan mavzularni takrorlash, 6-sinf kursiga poydevor yaratish.
   
2. 
   Tarbiyaviy maqsad: O’quvchilarga ta’lim birish bilan bir qatorda tarbiyasiga qarash , vatanini sevishni o’rgatish .
   
3. 
   Rivojlantiruvchi maqsad: o’quvchilarni savol javob taqarqatma matireallar bilan bilimini rivojlantirish.
   

Darsning ko’rgazmali qurollari: Tarqatma matiriallar, doska, bo’r va latta kerak bo’ladi.

Darsning borishi:
1. Tashkiliy qism – salom-alik qilish, davomatni tekshirish, zarur ko’rgazmali qurol va jihozlarni darsga hozirlash;

2. O’tilganlarni takrorlash va yangi mavzuni boshlashga hozirlik – yangi mavzu bilan bog’liq o’tilgan dars mavzularini takrorlash; o’quvchilarning yangi
mavzuni o’tishdan oldin bu mavzuga oid bilim darajalarini aniqiash, baholash
va yangi materialni o’zlashtirishga tayyorlash; yangi dars maqsadini tushuntirish;
3. Yangi mavzuni yoritish va Yangi mavzuni mustahkamlash:

5-sinfda natural va kasr sonlar ustida bajariladigan 4 amal (qo’shish, ayirish, ko’paytirish, bo’li bilan tanishganmiz.

2. O’tilganlarni takrorlash va yangi mavzuni boshlashga hozirlik – yangi mavzu bilan bog’liq o’tilgan dars mavzularini takrorlash; o’quvchilarning yangi
mavzuni o’tishdan oldin bu mavzuga oid bilim darajalarini aniqiash, baholash
va yangi materialni o’zlashtirishga tayyorlash; yangi dars maqsadini tushuntirish;
3. Yangi mavzuni yoritish va Yangi mavzuni mustahkamlash:

5-sinfda natural va kasr sonlar ustida bajariladigan 4 amal (qo’shish, ayirish, ko’paytirish, bo’lish) bilan tanishganmiz.
