Tushuntirish

Shakl simmetrik bo‘lsa, uni chiziq bilan ikki bir xil qismga bo‘lish mumkin. Bu chiziq — line of symmetry. Kapalak, baliq (old yoki yuqori tomondan qaralganda) va qisqichbaqaning simmetriya chizig‘i bitta. Starfish (dengiz yulduzi) beshta qo‘lga ega, uning beshta simmetriya chizig‘i bor. Gap: «A crab is symmetrical.» «A starfish has five lines of symmetry.»

Namunalar
A butterfly has one line of symmetry. Both wings match.
A starfish has five lines of symmetry.
Sinfda faoliyat

«Katlab tekshiring»: qog‘ozdan kapalak yoki yurak shaklini qirqib, ikkiga buking. Ikki yarim mos tushsa, «It’s symmetrical!» deymiz. Simmetriya chizig‘ini qalam bilan chizing.

Mashq
1
Kapalakning nechta simmetriya chizig‘i bor?
2
Starfishning nechta simmetriya chizig‘i bor?
3
Simmetriya chizig‘i nima qiladi?
4
Simmetrik narsadan bittasini ayting.
