IV. Yangi mavzuni mustahkamlash.

Yangi mavzuni mustahkamlash uchun o‘quvchilar guruhlarga ajratiladi. Har bir guruhga tengsizliklarni qanoatlantiruvchi qiymatni topishga doir topshiriqlar beriladi. Guruhlar bajargan ishlarini taqdimot qiladilar:

1-guruh:

a : 12 < 6 a = 0, a = 12, a = 24, a = 36, a = 48, a = 60.

a = 0 0 : 12 < 6 0 < 6

a = 12 12 : 12 < 6 1 < 6

a = 24 24 : 12 < 6 2 < 6

a = 36 36 : 12 < 6 3 < 6

a = 48 48 : 12 < 6 4 < 6

a = 60 60 : 12 < 6 5 < 6

2-guruh:

180 – a > 174 a = 0, a = 1, a = 2, a = 3, a = 4, a = 5.

a = 0 180–0>174 180 > 174

a = 1 180–1>174 179 > 174

a = 2 180–2>174 178 > 174

a = 3 180–3>174 177> 174

a = 4 180–4>174 176 > 174

a = 5 180–5>174 175 > 174

3-guruh:

38 + 2∙a < 47 a = 0, a = 1, a = 2, a = 3, a = 4.

a = 0 38+2∙0 <47 38+0 < 47 38 < 47

a = 1 38+2∙1 < 47 38+2 < 47 40 < 47

a = 2 38+2∙2 < 47 38+4 < 47 42 < 47

a = 3 38+2∙3 < 47 38+6 < 47 44 < 47

a = 4 38+2∙4 < 47 38+8 < 47 46 < 47

4-guruh:

6 ∙ a – 4 < 22 a = 1, a = 2, a = 3, a = 4.

a = 1 6 ∙ 1 – 4 < 22 6 – 4 < 22 2 < 22

a = 2 6 ∙ 2 – 4 < 22 12 – 4 < 22 8 < 22

a = 3 6 ∙ 3 – 4 < 22 18 – 4 < 22 14 < 22

a = 4 6 ∙ 4 – 4 < 22 24 – 4 < 22 20 < 22

5-guruh:

56 – 3 ∙ a > 42 a = 0, a = 1, a = 2, a = 3, a = 4.

a = 0 56 – 3 ∙ 0 > 42 56 – 0 > 42 56 > 42

a = 1 56 – 3 ∙ 1 > 42 56 – 3 > 42 53 > 42

a = 2 56 – 3 ∙ 2 > 42 56 – 6 > 42 50 > 42

a = 3 56 – 3 ∙ 3 > 42 56 – 9 > 42 47 > 42

a = 4 56 – 3 ∙ 4 > 42 56 – 12 > 42 44 > 42

V.Uyga vazifa berish.

O‘tilgan mavzu yuzasidan savol-javob o‘tkaziladi. 16- 17 topshiriqlar uyga vazifa qilib beriladi.

VI. O‘quvchilarni baholash.
