3. Tenglama.
248 : x = 2
x = 248 : 2
x = 124
248 : 124 = 2
2 = 2
4. Geometrik topshiriq.
Rasmda qanday shakllar bor?

4-sinf oʻquvchilari uchun orаliq nаzоrаt ishlari
1- nazorat ishi
1. Masala

Bo‘yi	Eni	Yuzi
12 m	5 m	?
?	4 dm	48 dm 2
10 sm	?	120 sm 2

Yechish:
1) 12 * 5 = 60 (sm2) yuzi
2) 48 : 4 = 12 (sm) bo‘yi
3) 120 : 10 =12 (sm) eni
Javob: yuzi = 60 sm, bo‘yi 12 sm, eni 12 sm.
