Mavzu: Tenglamalar va geometrik mazmundagi masalalar yechish

II. O’tgan mavzuni so’rash va mustahkamlash. Matematik diktant: 1) 500, 600, 700 sonlarini 200 ta orttiring. 2) 9 dan 90 gacha bo'lgan sonlarni 9 talab sanang. 3) 9 soni noma'lum sondan 5 ortiq. U qanday son? 4) 999 sonidan keyingi sonlarni yozing. 190 va 160 sonlarini 7 ga bo'ling. 5) Kamayuvchi 130, ayirma 35, ayiriluvchini toping. 6) 888 dan oldingi bir xil raqamli 3 xonali sondan 8ta yozing. 7) 15, 30, 45, 60, 75, 90 sonlaridan foydalanib bo'lishga doir misollar yozing. 8) Qaysi son 13 dan 5 marta ortiq. 9) 65 sonini I nechaga teng? 10) Sonni I qismi 30 ga teng, shu sonni toping.

   IV. Yangi mavzuni mustahkamlash.

800-misol

Tenglamalarni yeching: x · 36 = 4 968 · 7

X*36=34776

X=34776:36

X= 966

Tekshirish:

966*36=34776

4968*7= 34776

34776=34776
