Tushuntirish

3-D shakl – hajmli shakl (uzunlik, kenglik va balandlikka ega). Sphere – to‘p kabi, tekis yuzasi yo‘q. Cylinder – ikki tekis doira va egilgan yon yuza (masalan, konserva bankasi). Cone – bitta doira asos va uchi bor (muzqaymoq stakani). Cube – oltita teng kvadrat yuza (o‘yin kubigi). Pyramid – asosi ko‘pburchak, yon yuzalari uchburchak (Misr piramidalari). Kub 6 yuzali, 12 qirrali. Binolarda shakllarni qidiring: «The tower is a cylinder.»

Namunalar
The roof of the tent is a cone. The water tank is a cylinder.
A dice is a cube. A football is a sphere.
Sinfda faoliyat

«Shakl ovi»: sinf yoki ko‘chada 3-D shakl topish; har topilgan narsa uchun: «The clock is a cylinder.» Daftarga jadval to‘ldiring: shakl – narsa.
